彩色印刷該留意些什么？彩色印刷不只是單純性的正常情況下4色的進(jìn)行印刷,有很多海外的消費(fèi)者他們期刊雜志上常常會(huì)出現(xiàn)各種各樣專色撞出來的顏色,非常是有一類品紅顏色,這一個(gè)顏色是不好調(diào)的,另外許多 消費(fèi)者會(huì)使用到專色,或是進(jìn)行印刷完過水油,在彩色的基礎(chǔ)上增多黑印刷油墨的數(shù)量，始終不變混合色的顏色，包裝盒廠家在降低顏色明度的同時(shí)也使彩度降低，一般來說，在四色印刷的技術(shù)中，圖片的顏色是需要留意的一個(gè)問題了，因此，包裝盒廠家務(wù)必對四色印刷中的顏色問題多方面高度重視。
What should we pay attention to in color printing? Color printing is not just a simple four color printing under normal circumstances. Many overseas consumers often have a variety of spot colors on their magazines. There is a kind of magenta color, which is not easy to adjust. In addition, many consumers will use spot colors, or after printing with water and oil, increase the number of black printing inks on the basis of color, and keep the color of mixed colors unchanged, Packaging box manufacturers can reduce the brightness of color as well as the chroma. Generally speaking, in the four-color printing technology, the color of pictures is a problem that needs attention. Therefore, packaging box manufacturers must attach great importance to the color problem in four-color printing in many aspects.
這一個(gè)彩色設(shè)計(jì)要非常的留意下面四個(gè)方面：
This color design should pay attention to the following four aspects:
01掏空
01 Emptying
黃色底板上壓有一行藍(lán)色字，那樣包裝盒廠家在該菲林的黃色版上，藍(lán)色字所處具體位置就務(wù)必為空。反之藍(lán)版亦然。否則藍(lán)色的東西直接印在黃色上，顏色會(huì)造成發(fā)生變化，原本藍(lán)色的字變成了綠色。
A line of blue words is pressed on the yellow base plate, so that the specific position of the blue words on the yellow version of the film by the packaging box manufacturer must be empty. The blue version is the same. Otherwise, the blue things will be directly printed on the yellow, and the color will change, and the original blue words will become green.
02疊印
02 Overprint
某紅色底板上壓有一行黑灰色字，那樣包裝盒廠家在該菲林的紅色版上，黑灰色字所處具體位置也就不需要掏空。因黑灰色可壓著任何色，若將黑灰色具體內(nèi)容掏空，非常是一部分較小的文字內(nèi)容，進(jìn)行印刷時(shí)有點(diǎn)兒有誤差值便會(huì)造成外露白邊，而黑白色反差的對比又比較大，非常容易看得見。
A line of black and gray words is pressed on a red base plate, so that the packaging box manufacturer does not need to empty the specific position of the black and gray words on the red version of the film. Because black gray can be pressed against any color, if the specific content of black gray is hollowed out, it is a very small part of text content. When printing, there is a little error value, which will cause exposed white edges, and the contrast between black and white color is relatively large, which is very easy to see.
03四色黑
03 Four color black
這也是相對比較比較常見的相關(guān)問題。包裝盒廠家內(nèi)容輸出前有必要常規(guī)檢查出版發(fā)行文件格式內(nèi)黑色的文字內(nèi)容，尤其是是小字，會(huì)不會(huì)僅有黑板上面有，而在其余三色版上不應(yīng)該發(fā)生。假如如現(xiàn)，則印刷出來的成品質(zhì)量會(huì)打一折扣，RGB平面圖形轉(zhuǎn)化成CMYK平面圖形時(shí)，黑色的文字內(nèi)容一定會(huì)會(huì)轉(zhuǎn)換成四色黑。除非說特殊的設(shè)定，不然就有必要將其處理一下，才可內(nèi)容輸出菲林。
This is also a relatively common problem. Before the content output of the packaging box manufacturer, it is necessary to regularly check whether the black text content in the format of the published document, especially the small characters, can only be found on the blackboard, and should not occur on the other three color versions. If so, the quality of the printed products will be discounted. When RGB graphic is converted to CMYK graphic, the black text will be converted to four color black. Except for special settings, it is necessary to handle them before content can be output to film.
04圖像為RGB模式
04 Image in RGB mode
RGB模式的圖像內(nèi)容輸出時(shí)，RIP軟件系統(tǒng)一般的都能自動(dòng)的將其轉(zhuǎn)化成為CMYK基本模式內(nèi)容輸出。但其色相質(zhì)量會(huì)大打折扣，包裝盒廠家印出的成品色相淡，不明亮，實(shí)際效果很不大好。圖像合適在photoshop內(nèi)將其轉(zhuǎn)化成為CMYK基本模式，若為掃描儀稿件，那樣還有必要通過校色這一種工藝流程，圖像才可應(yīng)用。很多朋友在PS里面做文件格式的時(shí)候不會(huì)在意RGB和CMYK的格式。
When RGB mode image content is output, RIP software system can generally automatically convert it into CMYK basic mode content output. However, its hue quality will be greatly reduced. The finished products printed by the packaging box manufacturer are light and not bright, and the actual effect is not very good. The image is suitable to be converted into the CMYK basic mode in Photoshop. If it is a scanner manuscript, it is necessary to use the color correction process to apply the image. Many friends don't care about RGB and CMYK formats when they do file formats in PS.
包裝與紙質(zhì)印刷品的文件處理是非常非常重要的，因?yàn)樯视∷⑹怯∷⑵芳庸み^程的一步，這是不能出錯(cuò)的，如今的包裝盒廠家現(xiàn)在的設(shè)備都比以前更加，可以大大避免這類問題的出現(xiàn)。
The document processing of packaging and paper printed materials is very important, because color printing is a step in the processing of printed materials, which cannot be wrong. Today's packaging box manufacturers have more advanced equipment than before, which can greatly avoid such problems.
