噴繪寫真入門知識(shí)詳解
噴繪分兩種：一種是戶外廣告畫面輸出，一種是戶內(nèi)廣告畫面輸出。朋友們可根據(jù)實(shí)際情況訂做。一張噴繪成品的價(jià)格是以實(shí)際平方米數(shù)乘以每平方米的價(jià)格計(jì)算下來(lái)的，而設(shè)計(jì)費(fèi)用是以難度大小來(lái)收取，以下是兩大類的通用材料一覽：
A、戶內(nèi)寫真
1． PP膠片 （也就是我們俗稱的海報(bào)，精美膠質(zhì)、高精度、但后面沒(méi)有自帶的膠面，
客戶可用雙面膠貼在墻體上、可多次使用）
2．背膠 （和PP膠片的區(qū)別在于其有自帶的膠面，客戶撕開(kāi)后面薄膜后貼在墻體上）
3．相紙 （也是俗稱為海報(bào)，精美相紙質(zhì)、高精度、沒(méi)有自帶的膠面）
4．燈箱片
（精美的燈箱前的噴繪，它不同于我們平常見(jiàn)的招牌上面的噴繪，而是用于麥當(dāng)勞菜牌燈箱上的噴繪，具有圖像精美，透光性適中的特點(diǎn)）
5．背膠裱普通板
（就是將背膠貼上一種類似泡沫板的特制KT板上，然后四周加上邊條，形成一幅畫框，此材料輕便，可作為公司裝飾、展會(huì)展示用。）
6．背膠裱優(yōu)質(zhì)板 （和普通板的區(qū)別在于，其長(zhǎng)時(shí)間使用板面不會(huì)有氣泡產(chǎn)生。）
7．絹絲布 （
類似如絲綢狀的噴繪材質(zhì)，用于比較浪漫和格調(diào)高雅的展示場(chǎng)合，如服裝專賣店等）
8．油畫布 （用于比較浪漫和格調(diào)高雅的展示場(chǎng)，有一定的油畫質(zhì)感，可用于婚紗攝影體現(xiàn)等。）
9．透明背膠 （背膠的另一種，但是此類具有透明現(xiàn)象，多數(shù)用于門口張貼，
此材質(zhì)高貴大方、是展示公司形象的一種選擇。）
B、戶外噴畫
1． 戶外外光燈布 （我們看見(jiàn)的在戶外大型的噴繪，此類屬于燈光從外面射向噴布。）
2． 戶外內(nèi)光燈布 （我們看見(jiàn)的在戶外招牌上的噴繪，此類屬于燈光在燈箱中照射向外噴布。）
3．車身貼 （用于貼在車身上的噴繪、此類噴繪粘性好、抗陽(yáng)光）
4．戶外絹布（用于比較浪漫和格調(diào)高雅的展示場(chǎng)合，但此類可用于戶外）
5．網(wǎng)格布 （網(wǎng)狀噴繪材質(zhì)，用于客人的特殊表現(xiàn)手法來(lái)體現(xiàn)格調(diào)的一種材質(zhì)）
6．單孔透 （貼在車身玻璃上的材料，和車身貼一起使用）
戶內(nèi)使用的，它輸出的畫面一般就只有幾個(gè)平米大小。有一端限制1.5米的最大幅寬。在輸出圖象完畢還要覆膜（客人可選用光膜還是亞膜）、或裱板才算成品，輸出分辨率高，色彩比較飽和、清晰。戶外精度會(huì)比較小，尺寸不限，不用過(guò)膜。
噴繪寫真基本知識(shí)及注意事項(xiàng)
噴繪與寫真的圖象輸出要求
噴繪一般是指戶外廣告畫面輸出，它輸出的畫面很大，如高速公路旁眾多的廣告牌畫面就是噴繪機(jī)輸出的結(jié)果。輸出機(jī)型有：NRU
SALSA 3200
、彩神3200等，一般是3.2米的最大幅寬。噴繪機(jī)使用的介質(zhì)一般都是廣告布(俗稱燈箱布），墨水使用油性墨水，噴繪公司為保證畫面的持久性，一般畫面色彩比顯示器上的顏色要深一點(diǎn)的。它實(shí)際輸出的圖象分辨率一般只需要30~45DPI（按照印刷要求對(duì)比），畫面實(shí)際尺寸比較大的，有上百平米的面積。
寫真一般是指戶內(nèi)使用的，它輸出的畫面一般就只有幾個(gè)平米大小。如在展覽會(huì)上廠家使用的廣告小畫面。輸出機(jī)型如：HP5000，一般是
1.5米的最大幅寬。寫真機(jī)使用的介質(zhì)一般是PP紙、燈片，墨水使用水性墨水。在輸出圖象完畢還要覆膜、裱板才算成品，輸出分辨率可以達(dá)到300—1200DPI（機(jī)型不同會(huì)有不同的），它的色彩比較飽和、清晰。
下面我們簡(jiǎn)單介紹一下噴繪和寫真中有關(guān)制作和輸出圖象的一些簡(jiǎn)單要求。
1、尺寸大�。�
噴繪圖象尺寸大小和實(shí)際要求的畫面大小是一樣的，它和印刷不同，不需要留出出血部分。在噴繪公司一般在輸出畫面后都有留白邊的，一般情況都是留與凈畫面邊緣10CM。如圖你可以和噴繪輸出公司商定好，留多少邊用來(lái)打扣眼。價(jià)格是按每平米計(jì)算的，所以畫面尺寸以厘米為單位就可以了。
2、圖象分辨率要求：
噴繪的圖象往往是很大的，應(yīng)該明白“深在廬山不知廬山真面目”的道理。那噴繪圖象也是這樣，如果大的畫面還用印刷的分辨率，那就要累死電腦了。但是噴繪圖象分辯濾也沒(méi)有標(biāo)準(zhǔn)要求，下面是我個(gè)人使用不同尺寸時(shí)使用的分辨率，可以參考：
圖象面積（平方米） 180——無(wú)窮 30---180 1——30
分辨率（dpi） 11.25 22.5 45
說(shuō)明：因?yàn)楝F(xiàn)在的噴繪機(jī)多以11.25DPI、 22.5DPI、
45DPI為輸出時(shí)的圖象要求的，故合理使用圖象分辨率可以加快做圖速度。
寫真一般情況要求72DPI/英寸就可以了，如果圖象過(guò)與大（如在PHOTOSHOP新建圖象顯示實(shí)際尺寸時(shí)文件大小超過(guò)400M），可以適當(dāng)?shù)慕捣直媛�，控制�?00M以內(nèi)即可。
3、圖象模式要求：
噴繪統(tǒng)一使用CMKY模式，禁止使用RGB模式�，F(xiàn)在的噴繪機(jī)都是四色噴繪的，它的顏色與印刷色截然不同的，當(dāng)然在做圖的時(shí)候按照印刷標(biāo)準(zhǔn)走，噴繪公司會(huì)調(diào)整畫面顏色和小樣接近的。
寫真可以使用CMKY模式，也可以使用RGB模式。注意在RGB中大紅的值用CMKY定義，即M=100
Y=100。
4、圖象黑色部分要求：
噴繪和寫真圖象中都嚴(yán)禁有單一黑色值，必須填加C、M、Y色，組成混合黑。假如是大黑，可以做成：C=50
M=50 Y=50 K=100。特別是在PHOTOSHOP中用它帶的效果時(shí)，注意把黑色部分改為四色黑，否則畫面上會(huì)出現(xiàn)黑色部分有橫道，影響整體效果。
5、圖象儲(chǔ)存要求：
噴繪和寫真的圖像最好儲(chǔ)存為TIF格式，但是注意不可用壓縮的格式。
噴繪后期制作中的技術(shù)與技巧
后期制作是噴繪行業(yè)中不可缺少的工序，對(duì)整個(gè)工作的成敗、質(zhì)量的保證都起著很重要的作用。一個(gè)快捷、精致的后期制作，不僅可使作品錦上添花，還可以為公司創(chuàng)造更大的經(jīng)濟(jì)效益和企業(yè)信譽(yù)。后期制作概念廣泛，基本上所有設(shè)計(jì)制作工作之后的都屬于后期制作。例如有：輸出、剪裁、覆膜、裱板、拼接等等。結(jié)合我自己的一點(diǎn)經(jīng)驗(yàn)和本公司的實(shí)際情況，對(duì)后期工作作一點(diǎn)說(shuō)明。
輸出：圖像設(shè)計(jì)制作完畢后的首項(xiàng)工作便是輸出，在這個(gè)過(guò)程中，被輸出的圖像一定要合并所有層（layer），一般需存成.tif或.jpg
格式，如果圖像是在蘋果電腦上制作的話，須有后綴。對(duì)于圖像的大小，基本保持在100DPI上下即可達(dá)到輸出精度，如果所要輸出的圖像的圖面很大，點(diǎn)數(shù)不適當(dāng)降低，保證圖像的大小在40M以上。這個(gè)過(guò)程有幾點(diǎn)需注意的問(wèn)題：首先噴繪不同于印刷，噴繪的色彩要比印刷艷麗、好看得多。因此噴繪制圖中一定要設(shè)成RGB模式，而非CMYK模式。噴繪圖像的圖面往往很大，一些在印刷品上不易察覺(jué)的瑕庇大放大輸出后會(huì)變得很明顯夸張，而這點(diǎn)又無(wú)法通過(guò)小樣去發(fā)現(xiàn)，因此噴繪圖像在制作完畢一定要放大到100%仔細(xì)檢查一遍。對(duì)于文字很多的畫面，更要仔細(xì)校對(duì)。因?yàn)閲娎L輸出中沒(méi)有現(xiàn)成的色標(biāo)，因此在色偏的把握上要憑經(jīng)驗(yàn)，這才是打小樣的目的所在。
剪裁：畫面輸出完畢，機(jī)器將自動(dòng)裁紙。對(duì)于畫面大小與紙張相差較大需剪裁的，要量剪整齊。在我們裁膜時(shí)，也應(yīng)用剪刀沿著標(biāo)線走齊，因?yàn)闀?huì)方便在覆膜中的上膜工作，且更能保證質(zhì)量與成功率。
覆膜：“覆膜”工作是個(gè)“三人行”的項(xiàng)目，它對(duì)人員的合作性要求很高，一個(gè)成功的覆膜工作是“進(jìn)紙”“拉膜”和“搖滾”三者高度協(xié)調(diào)的產(chǎn)物。具體操作如下：在保證畫圖寬度合適的情況下，膜的長(zhǎng)度要適當(dāng)加長(zhǎng)一點(diǎn)（一般為20cm）。首先是調(diào)節(jié)滾子的旋扭，到手感到完全沒(méi)有阻力為止、微緊。將膜平展送入，保證在膜走動(dòng)的過(guò)程中不產(chǎn)生側(cè)偏，膜沒(méi)有受擠壓狀。然后，將膜拉起，在膜即將到頭時(shí)，將滾子穩(wěn)住，用力拉一下膜，保證端部平齊。此時(shí)，拉膜者下垂護(hù)膜
同時(shí)“進(jìn)紙”者可將畫面進(jìn)入（畫面的一端應(yīng)平齊），保證畫面平展、兩側(cè)與膜平行，當(dāng)準(zhǔn)備就序，可讓“搖滾”者緩緩搖動(dòng)，看到?jīng)]有問(wèn)題之后即可勻速前進(jìn)到頭。這一過(guò)程中，進(jìn)紙者要仔細(xì)檢查畫面上是否有頭發(fā)之類的東西，盡量清去。膜覆完后，即進(jìn)入“剪裁”工作。
裱板：當(dāng)客戶要求加板時(shí)，我們便進(jìn)入下一道裱板工序，和表裱常用的有兩種技術(shù)，即背膠紙型和噴3M膠型。二者相比，背膠型會(huì)更持久一些。背膠型：將畫面剪裁到所需尺寸，平整地放在展板上，將四邊對(duì)齊，中間用重物或由人壓住。將一端背膠揭開(kāi)約10公分的一條，粘貼到展板上。然后拿到覆膜機(jī)上，調(diào)節(jié)壓力至剛好通過(guò)展板為止。將已貼上畫面端進(jìn)入，拉起畫面，由一人抽出背膠紙，一人推展板到頭為止。噴膠型：對(duì)于四邊已有卡條的標(biāo)準(zhǔn)展板（規(guī)格如：120cmх90cm、90cmх60cm），我們更方便應(yīng)用噴膠的方法將展板平放，畫面平整地放在展板上。為了使畫面的四邊更好地懷展板邊緣吻合，我們先將畫面沿其中的相臨兩邊裁齊，而后從此兩邊為基準(zhǔn)，對(duì)齊展板的邊緣。把畫面與展板的相對(duì)位置固定（畫面上壓一重物或由其他人壓�。�，掀起已對(duì)齊的兩邊中的一邊，在其后的展板上噴膠，半分鐘后，將畫面兩邊拽緊，勻速下落，在這時(shí)由一人用刮板人畫面的中央向兩邊壓住畫面到畫面完全與展板貼合；同樣做法掀起畫面的另一端，噴膠后壓緊。最后用裁紙刀沿展板的卡條，將畫面多余的部分裁掉，即把整幅畫裱完。
拼接：當(dāng)客戶要求的畫面大過(guò)噴繪機(jī)的最大噴繪幅面時(shí)，我們會(huì)將畫面分開(kāi)輸出，然后再拼接在一起，
在做這種拼接的工作時(shí)，畫面的設(shè)計(jì)制作和輸出是其前提，因此每一步都步應(yīng)該有誤。首先畫面的拼接位置要弄清楚，倒底是誰(shuí)在上面，誰(shuí)在底下，哪張會(huì)更大一些，哪張會(huì)更小一些。在輸出過(guò)程中，因?yàn)橐敵龅漠嬅媸峭粡垐D，因此務(wù)必保持其色彩一致和大小相應(yīng)（比如說(shuō)寬一定），要記錄輸出時(shí)的設(shè)置參改，確保無(wú)誤。在進(jìn)行拼接的過(guò)程中，首先將兩幅畫要相接的一端整齊。然后在一個(gè)足夠的平面上將畫面展板，按正確的相對(duì)位置，把畫面放好，用膠條固定。掀起上展畫南相接部位的前端，噴膠（要遮住畫面不被噴膠）之后用刮板由中間向兩邊將畫面壓實(shí)貼緊。翻起上層畫面的另一端，在下層畫面的相接部分噴膠，壓實(shí)，即可將畫面接了。拼接好的畫面一定不可垂直接縫卷起，這樣很易在相接處產(chǎn)生皺褶，這點(diǎn)應(yīng)注意！
設(shè)計(jì)師有了好的創(chuàng)意‚構(gòu)思‚要把它轉(zhuǎn)為真實(shí)‚展示給觀者或戶‚才能被理解和認(rèn)同。‚因此‚掌握各種表現(xiàn)技法‚豐富設(shè)計(jì)的表現(xiàn)語(yǔ)言‚對(duì)設(shè)計(jì)師是至關(guān)重要的.
噴繪就是一種基本的、較傳統(tǒng)的表現(xiàn)技法，它具有著其它表現(xiàn)手法不可替代的特點(diǎn)和優(yōu)越性：A相對(duì)其它手繪技法，它的表現(xiàn)更細(xì)膩真實(shí)，可以超寫實(shí)的表現(xiàn)物象，達(dá)到以假亂真的畫面效果。B相對(duì)電腦、攝影等現(xiàn)代技法，它所表現(xiàn)的物象更自然，生動(dòng)。因此，掌握噴繪技法是設(shè)計(jì)師所必備的基本功，也是設(shè)計(jì)學(xué)科學(xué)生的一門必要的表現(xiàn)技法課。
一：工作原理和使用工具
1：以伯努利原理工作的虹吸壓力吹噴技術(shù)形成。
A：伯努力原理：流體速度越大，壓力則越小。
B：虹吸壓力吹噴技術(shù)：
氣體處A點(diǎn)受壓力通過(guò)水平吸管，B處形成低壓，把瓶中液體經(jīng)C管抽上形成霧化。
兩支相互垂直固定一起的開(kāi)口吸管‚其中一支插入裝有固定瓶中。
液體在兩管相交處被氣流沖擊而形成霧狀，變?yōu)殪F狀噴射出來(lái)。
C：噴筆也是基于這原理而設(shè)計(jì)，只是噴筆配有更精密、完善的設(shè)計(jì)元件，可以自由調(diào)節(jié)液體的濃度而獲得細(xì)密，均勻的顏色噴樣。
2：噴筆：
A：構(gòu)造原理：利用一個(gè)協(xié)同的閥桿組合，控制氣流和顏料流量，板掣可以上下啟動(dòng)，又可水平滑動(dòng)。水平滑動(dòng)時(shí)，掣桿的后連桿推動(dòng)節(jié)流針，以控制進(jìn)入氣流中的色量。通過(guò)拉退節(jié)流針，以使噴嘴的空隙截面積逐漸加大，混合氣的噴角也隨之增大。
1：噴針蓋：保護(hù)噴針。畫編輯部時(shí)可將針蓋卸掉。
2：噴嘴蓋：使空氣噴出時(shí)壓力均勻，形成氣體繞噴嘴旋轉(zhuǎn)噴出。
3：噴嘴：噴針的通道和顏色的出口、進(jìn)插噴針小心莫頂裂。
4：噴針：控制著噴嘴的啟閉。（嬌貴、清洗折洗一定注意勿壞）
B：噴筆操作：
以自然、輕松、活動(dòng)自如為原則。
1：手持噴筆開(kāi)始移動(dòng)。
2：按下板掣噴出空氣。
3：輕緩向后拖板掣，噴出顏色。
4：收筆相反。
5：噴繪下稿前，可先試噴檢測(cè)其色彩，噴量調(diào)整及有無(wú)故障出現(xiàn)，使之調(diào)正至最佳狀態(tài)。
C：噴筆保養(yǎng)：
1：清洗程序： 清洗色槽 －色槽注水－將噴量調(diào)制到最大，沖刷回饋。
2：拆洗：小心謹(jǐn)慎，擦凈涼干。
二：應(yīng)用范圍和功能：
噴樣是由無(wú)數(shù)細(xì)小顏色的顆粒組成的覆蓋面。每點(diǎn)顆粒都是以飽和的狀態(tài)霧化噴灑在畫面上，在霧化的瞬間，顏色的水份迅速蒸發(fā)，噴在畫面上的顏色幾乎是即干狀態(tài)。顏色的干濕變化很小，色彩變化易把握。
特點(diǎn)：A：色彩均衡鮮亮、平整、無(wú)筆觸。
B：可以任意推移變換色彩明度。宜
C：產(chǎn)生亞光效果，易制板。
D：便于修改。（必要時(shí)可先噴層白粉，再修。如：蘭＋白＋紅＝紅。）
E：疊色效果。（經(jīng)較少顏色去獲得豐富的色彩。）
1：背景大面積處理，色彩明度的推移。
2：主圖和背景過(guò)渡協(xié)調(diào)。
3：處理設(shè)備有缺點(diǎn)，背景不理想的照片。
4：效果圖、插圖。
5：制造繪畫或攝影達(dá)不到的效果。
三：方法和步驟：
1：對(duì)原稿素描和色彩關(guān)系的分折。
A：從亮部到暗部。 B：從深色到淺色。
2：對(duì)原稿進(jìn)行噴繪順序的分折。
A：刻模板的分析：先刻外形，整體把握。 B：模板制作：（準(zhǔn)確、合理。）
3：噴繪：（運(yùn)用疊色。）
A:噴灑亮部，中間調(diào)層次，鋪托暗部（基本單色素描，依靠基本色（固有色和
畫底相混合完成。）
B：加強(qiáng)中間調(diào)色彩層次，塑造暗部。
C：細(xì)部刻劃，整體協(xié)調(diào)。（從局部到整體，從整體到局部，反復(fù)市調(diào)正，增加
色彩層次。細(xì)部右噴繪結(jié)合反復(fù)進(jìn)行。）
虛噴：模板離開(kāi)紙面一定距離。
小噴量：（氣門小，噴針進(jìn)去少，筆距紙距離近。）
細(xì)膩：a：打底 b：噴過(guò)接色 c:：反復(fù) d：顏料厚薄適當(dāng)。 e：紙要光潔。
f：噴筆調(diào)好。 g：顏料新鮮。
四：精繪：
1；耐心。（做好準(zhǔn)備工作。）
2：任何部分都要用三大面處理。
3：顏色薄。
模板－磨刀誤砍柴功－事半功倍。
能用工具一定用工具： 能噴有地方，一定要用噴繪。
五：作業(yè)：
A：用幾何形體造型構(gòu)圖。（4－5件，須有一球體。）組織一圖。
造型自定向可直接取素描畫集上的幾何形體構(gòu)圖）。
色彩自設(shè)想（主題鮮明、和諧，背景簡(jiǎn)化處理。）
注重大關(guān)系協(xié)調(diào)，刻畫到位。（8開(kāi)，裱4開(kāi)紙。）
B：精繪：（16開(kāi)）
C：噴繪：（4開(kāi)）
六：工具準(zhǔn)備 ：
白卡紙（厚實(shí)、光挺。）
大板刷。
小狼圭。
小粉色。（新鮮，種類全）
乳膠。
噴繪與寫真的圖象輸出要求
噴繪一般是指戶外廣告畫面輸出，它輸出的畫面很大，如高速公路旁眾多的廣告牌畫面就是噴繪機(jī)輸出的結(jié)果。輸出機(jī)型有：NRU
SALSA
3200、彩神3200等，一般是3.2米的最大幅寬。噴繪機(jī)使用的介質(zhì)一般都是廣告布(俗稱燈箱布），墨水使用油性墨水，噴繪公司為保證畫面的持久性，一般畫面色彩比顯示器上的顏色要深一點(diǎn)的。它實(shí)際輸出的圖象分辨率一般只需要30~45DPI（按照印刷要求對(duì)比），畫面實(shí)際尺寸比較大的，有上百平米的面積。
寫真一般是指戶內(nèi)使用的，它輸出的畫面一般就只有幾個(gè)平米大小。如在展覽會(huì)上廠家使用的廣告小畫面。輸出機(jī)型如：HP5000，一般1.5米的最大幅寬。寫真機(jī)使用的介質(zhì)一般是PP紙、燈片，墨水使用水性墨水。在輸出圖象完畢還要覆膜、裱板才算成品，輸出分辨率可以達(dá)到300—1200DPI（機(jī)型不同會(huì)有不同的），它的色彩比較飽和、清晰。
噴繪和寫真中有關(guān)制作和輸出圖象的一些簡(jiǎn)單要求。
1、尺寸大小：
噴繪圖象尺寸大小和實(shí)際要求的畫面大小是一樣的，它和印刷不同，不需要留出出血部分。在噴繪公司一般在輸出畫面后都有留白邊的，一般情況都是留與凈畫面邊緣10CM。如圖你可以和噴繪輸出公司商定好，留多少邊用來(lái)打扣眼。價(jià)格是按每平米計(jì)算的，所以畫面尺寸以厘米為單位就可以了。
2、圖象分辨率要求：
噴繪的圖象往往是很大的，應(yīng)該明白“深在廬山不知廬山真面目”的道理。那噴繪圖象也是這樣，如果大的畫面還用印刷的分辨率，那就要累死電腦了。但是噴繪圖象分辯濾也沒(méi)有標(biāo)準(zhǔn)要求，下面是我個(gè)人使用不同尺寸時(shí)使用的分辨率，可以參考：圖象面積（平方米）
180—無(wú)窮 30---180 1——30分辨率（dpi） 11.25 22.5 45
說(shuō)明：因?yàn)楝F(xiàn)在的噴繪機(jī)多以11.25DPI、 22.5DPI、
45DPI為輸出時(shí)的圖象要求的，故合理使用圖象分辨率可以加快做圖速度。
寫真一般情況要求72DPI/英寸就可以了，如果圖象過(guò)與大（如在PHOTOSHOP新建圖象顯示實(shí)際尺寸時(shí)文件大小超過(guò)400M），可以適當(dāng)?shù)慕捣直媛�，控制�?00M以內(nèi)即可。
3、圖象模式要求：
噴繪統(tǒng)一使用CMKY模式，禁止使用RGB模式�，F(xiàn)在的噴繪機(jī)都是四色噴繪的，它的顏色與印刷色截然不同的，當(dāng)然在做圖的時(shí)候按照印刷標(biāo)準(zhǔn)走，噴繪公司會(huì)調(diào)整畫面顏色和小樣接近的。
寫真可以使用CMKY模式，也可以使用RGB模式。注意在RGB中大紅的值用CMKY定義，即M=100
Y=100。
4、圖象黑色部分要求：
噴繪和寫真圖象中都嚴(yán)禁有單一黑色值，必須填加C、M、Y色，組成混合黑。假如是大黑，可以做成：C=50
M=50 Y=50
K=100。特別是在PHOTOSHOP中用它帶的效果時(shí)，注意把黑色部分改為四色黑，否則畫面上會(huì)出現(xiàn)黑色部分有橫道，影響整體效果。
5、圖象儲(chǔ)存要求：
噴繪和寫真的圖像最好儲(chǔ)存為TIF格式，但是注意不可用壓縮的格式。
噴繪的尺寸。畫面有時(shí)候該放點(diǎn)出血的，如果機(jī)器縮布的話，不放出血，那打印出來(lái)的尺寸比電腦上的尺寸要小。尤其是大畫面的，則更明顯。一般出血我們是一米放0.1米的出血。當(dāng)時(shí)視各公司情況而定。
圖象顏色。如果客戶拿照片來(lái)掃描，要求做寫作，建議不要把色彩模式轉(zhuǎn)換為了CMYK模式。在原色彩模式上稍做調(diào)整就可。當(dāng)然，可得看掃描儀掃出來(lái)的結(jié)果而定。
寫真用RGB直接打印沒(méi)什么大礙，噴繪就不行。顏色偏太多了。圖象儲(chǔ)存要求。一直是tif格式的，但也可以存壓縮格式。關(guān)于點(diǎn)數(shù)，視情況而定。噴繪一般30dpi，寫真一般72dpi，如果畫面大，可以相應(yīng)縮小。我做過(guò)的最小點(diǎn)數(shù)是10dpi，300平方。再大的話，可以分幾段文件作。寫真一般不低于50dpi。關(guān)于點(diǎn)數(shù)小，畫面并不會(huì)變模糊，而是會(huì)產(chǎn)生較強(qiáng)的鋸齒，相反的，加大點(diǎn)數(shù)，拉大圖片的話，就會(huì)變模糊，而鋸齒少明顯點(diǎn)。一般做的話，可以雙管齊下，自行斟酌。
關(guān)于壓縮格式，一般的噴繪公司要求是用tiff，cmyk格式。其實(shí)用jpg也未嘗不可，但壓縮比必須高于8，不然畫面質(zhì)量無(wú)保證。對(duì)于原始圖片小，拉大后模糊的情況，可適量增加雜點(diǎn)。
注意：噴繪的圖像最好儲(chǔ)存為TIF格式，但是便于傳輸，可儲(chǔ)存JPEG格式。
Coreldraw、Freehand、Illustrator格式的文件必須將文字全部轉(zhuǎn)為曲線。
問(wèn)：我現(xiàn)在要做一個(gè)6米X3米的廣告，我想問(wèn)問(wèn)做這樣的廣告在PS里，文件的設(shè)置（多少dpi、要不要縮小多少倍等）如何？其中廣告里的內(nèi)容包括一個(gè)背景圖、一個(gè)圖標(biāo)、兩行文字介紹。最后輸出成什么格式呢？另外用CD做這樣的廣告，文件又如何設(shè)置？背景圖是否要在PS里按多大的比例做好后導(dǎo)入CD？
答：按實(shí)際尺寸設(shè)置，600*300CM，35DPI就可以了，噴繪在PHOTOSHOP做就可以了，不必在CORELDRAW里做。模式為CMYK的
，最后做成TIF圖或者PSD的圖交給噴繪公司。導(dǎo)入CORELDRAW做的話會(huì)很慢，所以不建議導(dǎo)入CORELDRAW
做。
問(wèn)：如果真的要在CD里面做，又如何設(shè)置其大小和分辯率呢？同時(shí)導(dǎo)入的背景圖用PS做其大小和分辯率又是多少？
答：如果文字比較多一點(diǎn)的話，而圖片比較簡(jiǎn)單，那是可以在CD里做的，多大嘛，我個(gè)人認(rèn)為在cd里做的話，PS里面的DPI可以高一點(diǎn)導(dǎo)出成tif的時(shí)候再把dpi設(shè)置成相應(yīng)的大小!
你要在CorelDRAW里做，導(dǎo)入位圖的分辨率(解析度)要看使用噴繪設(shè)備的精度如果是600DPI的噴繪，導(dǎo)入的位圖的分辨率(解析度)設(shè)置成150DPI原大即可。在CorelDRAW中制作比較好，因?yàn)槲淖质鞘噶康牟怀鲣忼X。
其實(shí)噴繪機(jī)并不是你設(shè)置到300DPI后噴繪精度就高很多的，噴繪公司從經(jīng)濟(jì)角度考慮，室內(nèi)相紙類，最高也就噴到300DPI就可以了，噴600DPI就浪費(fèi)了墨水（噴繪機(jī)可以噴到600DPI，現(xiàn)在有些甚至可以噴到1440DPI），所以我一般都不建議將分辨率設(shè)置到100DPI以上，當(dāng)然，如果文件很小，設(shè)置高些也無(wú)所謂，一般是75DPI左右噴出來(lái)就不會(huì)模糊了用于噴繪不要將RGB模式轉(zhuǎn)換成CMYK。因RGB色域要比CMYK大得多，色彩更鮮艷。印刷是由于無(wú)奈只好轉(zhuǎn)成CMYK模式。至于圖象精度你可以到輸出公司了解一下。作得太大，輸出時(shí)為了減少處理時(shí)間他也會(huì)給你改小。
這種說(shuō)法不敢茍同，RGB色域再寬，用墨水做顏色載體的噴繪也不能用它來(lái)再現(xiàn)電子文件的色彩，一般的噴繪機(jī)或噴墨打印機(jī)都是用CMYK及淺青、淺品六色墨水來(lái)再現(xiàn)色彩的，六色的色域雖不如RGB色域廣，但總比四色要廣的多，印刷用的彩色圖片在軟件中轉(zhuǎn)為CMYK是通過(guò)一組分色參數(shù)來(lái)實(shí)現(xiàn)的（根據(jù)印刷油墨特性），噴繪時(shí)如果用RGB圖像，是在噴繪（打�。�(qū)動(dòng)和噴繪（打�。C(jī)內(nèi)嵌的程序中轉(zhuǎn)換成青、品、黃、黑、淺青、淺品六色的（即分色過(guò)程），如果你用軟件將RGB圖為CMYK，一個(gè)問(wèn)題是分色參數(shù)不匹配（墨水不同于印刷油墨），再一個(gè)問(wèn)題是打噴繪時(shí)還要再將四色轉(zhuǎn)為六色，中間也有很大的損失，所以不如直接用RGB噴效果好�；就饽愕目捶ā娎L機(jī)的內(nèi)部工作模式仍然是四色方式。但其色域比較寬的原因一是噴繪的墨水的色純度和透明度比印刷油墨好；二是噴繪的色彩合成是墨水的混合而印刷則是油墨的疊加，因而其色彩飽和度好于印刷。至于淺品和淺青的使用主要是為彌補(bǔ)高光層次不全的缺陷。我們?cè)趥鹘y(tǒng)印刷中也使用這種六色法。日本Roland八色噴繪機(jī)采用Panton六色高保真技術(shù)，其主要是多了亮綠和亮橙兩色，因此其色域要比一般六色噴繪機(jī)大得多，基本涵蓋了90%的Panton色域。
問(wèn)：那么是用RGB好呢還是用CMYK好？
答：如果你用RGB給一個(gè)變態(tài)客戶噴一幅黑底白字的東東，黑色將由RGB疊加起來(lái)才可以得到，濕度有多大，用的墨水要多少，這樣又浪費(fèi)，又難干，又傷噴頭，過(guò)了一個(gè)星期后，還會(huì)出現(xiàn)滲色的現(xiàn)象，到時(shí)叫你賠錢，你哭都沒(méi)時(shí)間，如果我用CMYK文件，只用到一個(gè)黑色就可以了，而且絕不滲色，不信你可以試試。
問(wèn)：一家噴繪公司，客戶將設(shè)計(jì)稿拿來(lái)，作為噴繪公司這方在Photoshop中一般要做那些方面的調(diào)整。有哪些該注意的地方。
答：調(diào)整顏色，使噴繪機(jī)噴出來(lái)的圖達(dá)到客戶的要求。
問(wèn)：作為噴繪公司的操作人員，一般要做哪些工作。設(shè)計(jì)已由客戶完成，難道只是將客戶的文件放入電腦然后在PS中打開(kāi)和調(diào)整，然后就開(kāi)機(jī)噴繪了嗎？還需要哪方面的知識(shí)！
答：有時(shí)候客戶設(shè)計(jì)稿是很小的，你需要將它放大，調(diào)整顏色，處理一下畫面的缺陷，或者有時(shí)候客戶會(huì)FAX新的圖的SIZE給你，你按他要的SIZE改變畫面。
Detailed knowledge of inkjet entry
Printing in two ways: one is outdoor advertising screen output, one is indoor advertising screen output. Friends can be customized according to the actual situation. An inkjet product prices based on actual number of square meters calculated by multiplying the price per square meter down, designed to charge fees based on the size of the difficulty, the following are two categories of common materials at a glance:
A, indoor photo
1. PP film (what we called the poster, fine glial precision, but comes with the plastic surface is not followed, the customer can be double-sided adhesive tape on the wall, can be used repeatedly)
2. Adhesive (and PP film distinction lies in its own plastic surface, the customer behind the film after tearing posted on the wall)
3. Paper (also known as posters, fine paper with high precision and no built-in plastic surface)
4. Box film (beautifully light box before printing, which is different from the common signs above our level inkjet, but McDonald's menus for printing on boxes with images beautifully translucent moderate features)
5. Adhesive mounted ordinary plate (gum paste is to a similar special KT board foam board, then four weeks plus side, the formation of a frame, this material is lightweight, can be used as decoration company, exhibition display purposes.)
6. High adhesive mounting plate (and the common difference is that the board, the board does not have long-term use bubbles.)
7. Silk cloth (similar to printing such as silk-like material, for more romantic and elegant display of occasions, such as clothing stores, etc.)
8. Canvas (for more romantic and elegant exhibition hall, there is a certain painting texture, can be used for wedding photography reflects and so on.)
9. Transparent adhesive (adhesive another, but such a transparent phenomenon, mostly for the door post, this material is noble and generous, is to demonstrate the company's image as an option.)
B, Outdoor Inkjet
1. Outdoor outside light cloth (we have seen in the large outdoor inkjet, these belong to the light from the outside toward the spraying.)
2. Outdoor inner light cloth (we see signs on the outdoor inkjet, these are light irradiation in the lightbox spraying outward.)
3. Body stickers (stickers on the vehicle body for inkjet, inkjet such viscous, anti-sun)
4. Outdoor raw silk (for more romantic and elegant showcase occasion, but such can be used outdoors)
5. Mesh (mesh printing material, a special performance for the guests as a way to reflect the style material)
6. Hole through (attached to the body of the glass material, and body paste together)
Indoor use, and it outputs the picture size generally only a few meters. Has an end limit maximum width of 1.5 meters. Also covered in the output image is completed (guests can choose film or Asian film), or paper board considered finished, the output high resolution, colors more saturated and clear. Outdoor accuracy will be relatively small, the size limitation, do not cross the membrane.
Basic knowledge of inkjet printing with photo and notes image output requirements
Printing generally refers to outdoor advertising screen output, it outputs a large screen, such as a large number of highway billboard screen printing machine output is the result. Output models are: NRU SALSA 3200, 3200 color of God, etc., is generally the maximum width of 3.2 meters. Inkjet printers are generally used media advertising cloth (commonly known as the banner), use of oil-based ink ink, screen printing company in order to ensure the durability of the general picture color than the color on the monitor a little deeper. It is actually the output image resolution is generally only need 30 ~ 45DPI (printing requirements in accordance with contrast), the picture is the actual size is relatively large, there are hundreds of square meters of area.
PHOTO generally refers to indoor use, it outputs the picture size generally only a few meters. If the exhibition manufacturers use small advertising screen. Output models such as: HP5000, is generally the maximum width of 1.5 meters. Pictures of the media is generally PP paper, light film, ink, water-based ink used. Also in the output image is completed film, paper board considered finished, the output resolution can be achieved 300-1200DPI (different models have different), it is more saturated colors, clear.
Below we briefly inkjet and photo images relating to production and output some simple requirements.
1, size:
Printing an image size and the actual requirements of the screen size is the same, different printing it, without leaving a bleeding part. In the printing companies generally have a blank screen is displayed on the output side, in general, are left edge of the screen with a net 10CM. As you can, and the company agreed on a good printing output, leaving many sides to fight buttonhole. Prices are per square meter basis, so the screen size in centimeters on it.
2, the image resolution requirements:
Printing images tend to be very large, should understand that "deep in Lushan do not know the true colors" of the truth. That inkjet image the same way, if the big screen but also with printing resolution, it should be worn computer. However, there is no filter inkjet image differentiate standard requirements, the following is my personal use of different sizes at the same resolution, you can refer to:
Image area (sqm) 180 - infinity 30 --- 180 1 - 30
Resolution (dpi) 11.25 22.5 45
Note: Because inkjet printers are now mostly 11.25DPI, 22.5DPI, 45DPI image is output requirements, it is reasonable to use the image resolution can be done to speed up drawing speed.
PHOTO general requirements 72DPI / inch on it, and if the image too large (as in PHOTOSHOP New images show the actual size when the file size exceeds 400M), you can drop the appropriate resolution can be controlled at less than 400M.
3, the image mode requires:
Inkjet unified use CMKY mode, prohibit the use RGB mode. Now all four-color inkjet printing machine, its distinct color and process color, of course, make plans to go when printing standards in accordance with, the company will adjust the picture color inkjet and sample close.
Photo may be used CMKY mode, you can also use the RGB mode. Note that the RGB values ??in the red with CMKY definition, namely M = 100 Y = 100.
4, the black part of the image requirements:
Inkjet and photo images are prohibited with a single black values, you must fill plus C, M, Y color, composition of mixed black. If it is a large black, can be made: C = 50 M = 50 Y = 50 K = 100. Especially in PHOTOSHOP used it with effect, pay attention to the black part of the four-color black, or black part will appear on the screen with Gantt, affect the overall results.
5, the image storage requirements:
Inkjet and photo images saved as TIF format is best, but careful not to use a compressed format.
Post-production inkjet technology and techniques
Post-production is indispensable for the printing industry processes, the success or failure of the whole, quality assurance plays a very important role. A fast, sophisticated post-production, not only can work icing on the cake, but also that the company to create greater economic and corporate reputation. Extensive post-production concept, essentially all of the design work after all belong to post-production. For example: output, cut, film, paper board, stitching and so on. Combined with a little of my own experience and the company's actual situation, a few notes on the late work.
Output: Graphic Design After making the first task is to output, in the process, the image must be output merge all layers (layer), which normally takes saved as. Tif or. Jpg format, if the image is in the Apple Computer produced on the case, to have the suffix. The size of the image, remained in the bottom 100DPI output accuracy can be achieved, if the image to be output surface is large, reduce improper points, to ensure the size of the image more than 40M. This process has several points need to be noted: First, unlike inkjet printing, inkjet printing color than the gorgeous, pretty much. Therefore inkjet Drawing must be set to RGB mode instead of CMYK mode. Printing images are often large drawings, printed on some imperceptible flaws Bailey big amplifier output becomes very obvious after exaggerated, and this point is unable to discover through the sample, so in the production of finished printing the image must be enlarged to 100 % double check again. For a lot of screen text, but also to carefully proofread. Because there is no ready-made inkjet output color, so the color cast to grasp empirically, this is the play sample that purpose.
Cut: the screen output is completed, the machine will automatically cut. For the larger screen size and the paper to be cut away, to the amount of cut and tidy. When we cut the film, also used scissors to go along marking homogeneous, because it will facilitate the work of film in the film, and to better ensure the quality and success rate.
Film: "Film" Work is a "three-line" items, it co-workers demanding a successful film work is "Feed" and "pull film" and "rock" of the three highly coordinated product. Specific operation is as follows: to ensure appropriate circumstances drawing width, extended to the appropriate length of the film dot (usually 20cm). First, adjust the roller knob, hand feel absolutely no resistance so far, slightly tight. Flattened into the membrane, the membrane move to ensure the process does not produce cornering, film is not squeezed shape. Then, pull the film, the film coming to its end, the rollers hold, pull hard film to ensure the end of the flush. At this time, pull the film by drooping cuticle while "feeding" may enter the picture (picture should end flush), to ensure the screen flat, parallel to the film on both sides, when ready to order, you can let the "rock" by slow slow shaking, you can see there is no problem after uniform forward head. This process, those who feed on the screen to carefully check whether there is hair and stuff, try to clear out. After film coating, ie into the "tailoring" work.
Framed board: When a customer asks for board, we will proceed to the next step of a mounting plate, and table mounted, there are two commonly used techniques, namely papier-mache and spray adhesive 3M adhesive type. Compared the two, some of gum type will be more durable. Adhesive Type: cut to the desired size of the screen, flat panels placed on the four sides of the alignment, in the middle with a heavy object or person to suppress. The end of the backing of about 10 cm a kick and paste it into panels on. Then get laminating machine, adjust the pressure to just through panels so far. The end of the screen affixed to enter, pull up the screen, draw back tape by one person, a person boards the head forward so far. Glue type: For four sides of the existing card standard panels (specifications, such as: 120cmх90cm, 90cmх60cm), we will facilitate the application of spray methods flat panels, flat screen placed on the panels. In order to make the four sides of the screen edge panels fit better pregnant, we first screen along one of the adjacent sides cut Qi, then from both sides as the base, align the edges of panels. The picture and the relative position of the fixed panels (a heavy pressure on the screen or by others to suppress), set off on both sides has been aligned in the side panels on the glue in the subsequent, after half a minute, pulled tight on both sides of the screen, uniform whereabouts at this time by a person with a scraper who hold the center of the screen to both sides of the screen to display complete with panels fit; likewise set off the other side of the screen, spray after compression. Finally, card cutter bar along the boards, cut the excess part of the picture, that is the whole painting framed finish.
Stitching: when a customer requests a screen larger than the maximum printing format inkjet printers, we will separate the output screen, and then spliced ??together, doing the work of this mosaic, the picture of the design and the output is the premise, so every step of the step should be incorrect. First picture stitching position to figure out who the hell is on top, who is at the bottom, which Zhang will be even greater, which Zhang will be smaller. In the output process, because the picture is to be output with a map, so be sure to maintain its consistent color and size accordingly (for example, a certain width), when you want to record the output parameters to change the settings to ensure correct. During the splicing process, the first picture to be connected to one end of the two neat. Then on a flat surface in an adequate screen panels in the correct relative position of the screen away, and fixed with tape. Set off on a painting exhibition connecting parts of the southern front, glue (not glue to cover the screen) followed by the scraper from the middle to both sides of the screen compaction snapping. The other end of the upper screen flips, in the lower part of the screen in contact spray, compaction, to pick up the screen. Stitching good vertical joints must not roll up the screen, so it is easy to generate creases in phase at this point should be noted!
Designers have good ideas, ideas, turning it into a true show to viewers or households, in order to be understood and recognized. Therefore, to master a variety of performance techniques, the performance of rich design language, the designer is essential.
Printing is a basic, more traditional performance techniques, it has the performance practices irreplaceable other features and advantages: A hand-drawn relative to other techniques, its performance is more delicate true, can the performance of ultra-realistic images, to achieve real ones picture effect. B relative to computers, photography and other modern techniques, the performance of the images it is more natural and vivid. Therefore, the master designer inkjet technique is necessary for basic skills, but also the design of a student's academic performance techniques necessary lessons.
A: working principle and the use of tools
1: Bernoulli's principle works siphon pressure blowing spray technique.
A: Bernoulli's principle: the greater the fluid velocity, the pressure is smaller.
B: Siphon pressure blowing spray techniques: gas under pressure at point A by horizontal straw, B formed at low pressure, the bottle pumping liquid through the tube to form C atomization. Two mutually perpendicular fixed opening with straw, where an insert with fixed bottle.
The liquid in the two intersect to form a mist by air shocks, into mist spray out.
C: Airbrush is also based on this principle and design, but with a more sophisticated airbrush, perfect design elements, you can freely adjust the concentration of the liquid obtained fine, uniform color spray pattern.
2: Airbrush:
A: Aufbau principle: the use of a synergistic combination of the stem to control airflow and paint flow, plate up and down start button, but also slide horizontally. Horizontal slide, the catch lever push rod after the throttle pin to control the amount of color into the air. Back by pulling the throttle pin to the gap of the nozzle cross-sectional area gradually increased, the ejection angle of the mixture increases.
1: The needle cover: Protection of the needle. Painting editorial needle cap can be removed.
2: The nozzle cap: so that the air pressure is uniformly ejected, forming gas around the rotating spray nozzle.
3: Nozzle: needle outlet channel and colors, insert the needle into the top Mo accidentally cracked.
4: Needle: controls the opening and closing of the nozzle. (Delicate, cleaning must pay attention not to wash off bad)
B: Airbrush Action:
Natural, relaxed, freedom of movement principle.
1: Handheld Airbrush start moving.
2: Press the panel button blowing air.
3: gently backwards carriage valves, spray color.
4: collection pen opposite.
5: The following is issued before printing, you can first try to detect the color spray, spray volume adjustment and whether the fault occurs, so that alignment to the best condition.
C: Airbrush maintenance:
1: Cleaning Procedure: Cleaning color tank - color tank water - will spray volume modulation to the maximum scour feedback.
2: washable: careful, wipe dry.
II: Applications and features:
Spray pattern is composed of numerous tiny particles of color coverage. Each point in the saturation state particles are atomized spray on the screen, the atomizing the moment, the color of the rapid evaporation of water, sprayed on the screen color is almost dry state. Little change in the color of wet and dry, color changes and easy to grasp.
Features: A: bright color balance, flat, no strokes.
B: You can transform any lapse color brightness. Should
C: generating matte effect, easy system board.
D: easy to modify. (If necessary, the first layer of white spray, then repair, such as: blue + white + red = red.)
E: overlapping color effects. (The fewer colors to get rich color.)
1: Background large area processing, color brightness over time.
2: The main picture and background transition coordination.
3: The processing device has the disadvantage background is ideal photo.
4: renderings, illustrations.
5: Manufacturer painting or photography unattainable results.
III: Methods and steps:
1: The relationship between the original sketch and color points off.
A: From highlight to dark. B: From dark to light.
2: The order of the manuscript for printing sub-fold.
A: engraved template analysis: first carved appearance, the overall grasp. B: Template Production: (accurate and reasonable.)
3: Printing: (use of overlapping color.)
A: Spray highlights, midtones level, paved prop dark (basic monochrome sketch, relying on the basic color (natural color and mixed finish painting the bottom.)
B: Strengthening midtone color levels, shaping dark.
C: detail characterize the overall coordination. (From the local to the whole, from global to local, repeated market research is to increase the color levels.
Detailing the right combination of repeated printing.)
Virtual Spray: template off the paper a certain distance.
Spray a small amount: (valve small needle into the small pen from the paper from the past.)
Delicate: a: primer b: sprayed repeatedly pick the color c :: d: paint thickness appropriate. e: Paper to be bright and clean. f: spray style is good. g: fresh paint.
Four: painted:
1; patience. (Ready to work.)
2: to be used for any part of the three surface treatment.
3: Color thin.
Template - Brothers tests the sincerity - do more with less.
Tool must be able to use tools: can spray a place, be sure to use inkjet.
Five: Assignment:
A: Composition with geometric shapes. (4-5 pieces, there must be a sphere.) Organized a chart.
Modeling can be taken directly from the orientation on the sketch geometry Illustration composition).
Since color vision (clear theme, harmony, background simplified.)
Focus on large relations coordination, portrayed in place. (8 open, mounted four open paper.)
B: painting of: (16 open)
C: Printing: (4 open)

Inkjet and photo image output requirements
Printing generally refers to outdoor advertising screen output, it outputs a large screen, such as a large number of highway billboard screen printing machine output is the result. Output models are: NRU SALSA 3200, 3200 color of God, etc., is generally the maximum width of 3.2 meters. Inkjet printers are generally used media advertising cloth (commonly known as the banner), use of oil-based ink ink, screen printing company in order to ensure the durability of the general picture color than the color on the monitor a little deeper. It is actually the output image resolution is generally only need 30 ~ 45DPI (printing requirements in accordance with contrast), the picture is the actual size is relatively large, there are hundreds of square meters of area.
PHOTO generally refers to indoor use, it outputs the picture size generally only a few meters. If the exhibition manufacturers use small advertising screen. Output models such as: HP5000, general maximum width of 1.5 meters. Pictures of the media is generally PP paper, light film, ink, water-based ink used. Also in the output image is completed film, paper board considered finished, the output resolution can be achieved 300-1200DPI (different models have different), it is more saturated colors, clear.
Inkjet and photo images relating to production and output some simple requirements.
1, size:
Printing an image size and the actual requirements of the screen size is the same, different printing it, without leaving a bleeding part. In the printing companies generally have a blank screen is displayed on the output side, in general, are left edge of the screen with a net 10CM. As you can, and the company agreed on a good printing output, leaving many sides to fight buttonhole. Prices are per square meter basis, so the screen size in centimeters on it.
2, the image resolution requirements:
Printing images tend to be very large, should understand that "deep in Lushan do not know the true colors" of the truth. That inkjet image the same way, if the big screen but also with printing resolution, it should be worn computer. However, there is no filter inkjet image differentiate standard requirements, the following is my personal use of different sizes at the same resolution, you can refer to: the image area (sqm) 180 - infinity 30 --- 180 1 - 30 Resolution (dpi ) 11.25 22.5 45
Note: Because inkjet printers are now mostly 11.25DPI, 22.5DPI, 45DPI image is output requirements, it is reasonable to use the image resolution can be done to speed up drawing speed.
PHOTO general requirements 72DPI / inch on it, and if the image too large (as in PHOTOSHOP New images show the actual size when the file size exceeds 400M), you can drop the appropriate resolution can be controlled at less than 400M.
3, the image mode requires:
Inkjet unified use CMKY mode, prohibit the use RGB mode. Now all four-color inkjet printing machine, its distinct color and process color, of course, make plans to go when printing standards in accordance with, the company will adjust the picture color inkjet and sample close.
Photo may be used CMKY mode, you can also use the RGB mode. Note that the RGB values ??in the red with CMKY definition, namely M = 100 Y = 100.
4, the black part of the image requirements:
Inkjet and photo images are prohibited with a single black values, you must fill plus C, M, Y color, composition of mixed black. If it is a large black, can be made: C = 50 M = 50 Y = 50 K = 100. Especially in PHOTOSHOP used it with effect, pay attention to the black part of the four-color black, or black part will appear on the screen with Gantt, affect the overall results.
5, the image storage requirements:
Inkjet and photo images saved as TIF format is best, but careful not to use a compressed format.
Printing size. Screen sometimes bleeding of the discharge point, if the machine Shrinking, then hold bleeding, then print out the size than the smaller size on the computer. Especially large screen, even more apparent. We are one meter bleeding usually placed 0.1 m bleeding. At that time, as the case may be, each company.
Image colors. If the customer to take photo to scan, do the writing requirement, it is recommended not to convert the color mode to CMYK mode. In the original color mode can be slightly adjusted. Of course, we get to see the scanner sweep out the results may be.
Direct photo printing with RGB nothing serious, printing can not. Color slants too much. Image storage requirements. Tif format always, but can also be stored compressed format. About points, as the case may be. Inkjet general 30dpi, portrait generally 72dpi, if the picture is big, can be reduced accordingly. I have done the minimum number of points is 10dpi, 300 square feet. And then a big, you can file for sub-paragraphs. PHOTO generally not less than 50dpi. On small points, the picture is not blurred, but will produce a strong serrated, on the contrary, increase the number of points, pull the big picture, it would become blurred, and the less obvious point serrated. Generally do so, you can two-pronged approach, at their discretion.
About compression format, the general requirements of printing companies is tiff, cmyk format. Actually not a bad idea to use jpg, but the compression ratio must be greater than 8, otherwise the picture quality is not guaranteed. The original picture is small, after widening ambiguous situations can increase the amount of noise.
Note: The printing images saved as TIF format is best, but easy to transport, store JPEG format. Coreldraw, Freehand, Illustrator file format all text must be converted to curves.
Q: I need to do now a 6-X3 meters of advertising, I would like to ask to do this advertisement in PS, file settings (how many dpi, not to reduce the number of times, etc.) How? Where the content of the ad, including a background image, an icon, and two lines of text presentation. Final output into what format it? Also with the CD to do this advertisement, file and how to set up? Background image you want in PS ready, according to what percentage of imported CD?
A: The actual size is set, 600 * 300CM, 35DPI can, printing can be done in PHOTOSHOP, CORELDRAW years do not have to do that. Mode to CMYK, and finally made TIF or PSD diagram to figure printing company. Importing CORELDRAW do so will be very slow, so I do not recommend importing CORELDRAW
Do it.
Q: If you really want to do inside the CD, but also how to set the size and resolution of it? While import background images with PS do its size and resolution and how much?
A: If the text a bit more, then, and the picture is relatively simple, it is in the CD to do, how much Well, I personally think that the cd doing so, PS inside the DPI can be a little higher export to tif, when then dpi set to the appropriate size! CorelDRAW where you are going to do, import a bitmap resolution (resolution) depends on the accuracy of using inkjet equipment inkjet 600DPI If the imported bitmap resolution (resolution) is set to 150DPI original large can. Produced in CorelDRAW better, because the text is not a vector jagged. In fact Inkjet Printer not printing after you set up to 300DPI accuracy is much higher, printing company from the economic point of view, indoor paper category, the highest it can be sprayed onto 300DPI, 600DPI wasted ink jet (inkjet printers can be sprayed to 600DPI, now some can even be sprayed onto 1440DPI), so I generally do not recommend setting the resolution to 100DPI more, of course, if the file is small, it does not matter to set higher, usually around 75DPI erupted not blurred Do not use for printing RGB mode into CMYK. RGB gamut due to larger than CMYK, the color more vivid. Printing is due no choice but to turn into CMYK mode. As for the accuracy of the image to the output you can look at the company. As too large, the output in order to reduce processing time when he will give you piecemeal. This argument can not agree, RGB color gamut and then wide, made with ink inkjet color carrier nor can it to the color reproduction of electronic documents, the general inkjet printers or inkjet printers are in CMYK and light cyan, light magenta six inks to reproduce color, six-color gamut RGB color space, though not as wide, but better than four colors to be more extensive, printing color pictures to CMYK in software is a component of the color parameters to achieve ( according to the printing ink characteristics), when printing RGB images if, in the printing (printing) driver and printing (printing) machine programs embedded into cyan, magenta, yellow, black, light cyan, light magenta six-color ( ie separation process), if you use software to RGB Pictured CMYK, one problem is separation parameters do not match (unlike ink printing ink), and then a question and then when they hit four-color printing into six colors, the middle is also a great loss, so as the direct use RGB spray effect. Basically agree with you. Printer's internal working model is still four-color mode. However, it causes a relatively wide gamut one inkjet ink color purity and transparency, better than printing ink; Second, the color inkjet ink mixing synthesis printing ink is superimposed, and thus its color saturation in print. As light magenta and light cyan used primarily to compensate for high light levels insufficiency defects. We also used in traditional printing method that six colors. Japan's eight-color Roland six-color inkjet printers using Panton-fidelity technology, which is mainly more bright green and bright orange and white, so the color gamut than the average six-color inkjet printers is much larger, covering 90% of the Panton color domains.
Q: What is good with RGB or CMYK good use?
A: If you use RGB to an abnormal client stuff sprayed a white on black, black RGB will stack up before they can get, how much moisture, how much ink is used, so that they waste, and hard to do, but also hurt the nozzle , over a week later, there will be bleeding phenomenon called when you lose money, you cry no time, if I use CMYK documents, only use a black can, and never bleed, do not believe you you can try.
Q: a printing company, the client will design artwork used as a printing company that parties generally do in Photoshop to adjust those aspects. What are the caveats.
A: Adjust color inkjet printers spray to make the chart to meet customer requirements.
Q: As a printing company operator, generally do what work. Design by customers to complete, it just the customer's file into your computer and then open and adjust in PS, and then start printing yet? Which aspects of the knowledge needed!
A: Sometimes the customer design artwork is very small, you need to zoom in, adjust color, look picture processing defects, or sometimes FAX new customers will give you a map of SIZE, SIZE you want to change according to his screen.
