印刷廠印刷刊物時(shí)的四色黑,如何處理效果好
How to deal with the four-color black when printing publications
印刷廠印刷顏色的時(shí)候,對(duì)黑色有一個(gè)稱呼,即“4色黑”,這是什么意思呢,在常見的印刷是CMYK模式是如何實(shí)現(xiàn)黑色印刷的呢?我們一起來(lái)看看吧。
When printing color, the printing factory has a name for black, that is, "4-color black". What does this mean? How does the common printing mode CMYK realize black printing? Let's have a look.
很多剛做設(shè)計(jì)的設(shè)計(jì)師(特別是插畫師)在選擇黑色的時(shí)候,都會(huì)選擇C:93,M88,Y89,K80的黑:
Many designers (especially illustrators) who have just done design will choose black color of C: 93, M88, Y89, K80 when choosing black color:
由于很多情況他們都是在RGB顏色哪里直接調(diào)色,在轉(zhuǎn)化成CMYK的時(shí)候,黑色就會(huì)變成這個(gè)黑了,殊不知這個(gè)色,會(huì)讓你的印刷品的背面,臟得一塌糊涂,由于每個(gè)顏色都幾乎覆蓋了80%以上的油墨,在飛快的印刷中,油墨還沒(méi)干透,下一張就已經(jīng)印好,蓋在這張上面,要知道,印刷157g銅版紙,每小時(shí)是可以去到10000多張的,而且你不是印100幾十張,也有1000張,1000張按A4紙的大小,也有10KG,更別說(shuō)你是印畫冊(cè),1000張下來(lái),就是80多KG了,這重量壓下來(lái),背面肯定會(huì)沾到這些不干的油墨。
In many cases, they directly mix colors in RGB colors. When they are converted to CMYK, black will become this black. It is unknown that this color will make the back of your print dirty. Since each color covers almost 80% of the ink, the ink is not completely dry in fast printing. The next one has been printed and covered on this one. You should know, 157g coated paper is printed, More than 10000 pieces can be printed every hour. Besides, you can print not only 100 dozens of pieces, but also 1000 pieces. 1000 pieces can also be 10KG according to the size of A4 paper, let alone you can print a picture album. If you print 1000 pieces, it will be more than 80 KG. The back will definitely be stained with these non dry inks when the weight is pressed down.
如果是文字的話,印刷廠會(huì)都會(huì)幫你把這顏色改成C0,M0,Y0,K100,如果是插畫、圖片類的話,在印刷過(guò)程中,發(fā)現(xiàn)了,要么修改文件,要么噴多點(diǎn)粉(色塊小的可以),然后把速度降下來(lái)。還有個(gè)辦法就是換機(jī)器,換成UV機(jī)來(lái)印刷,不過(guò)成本很高,而且油墨偏暗,沒(méi)有普通油墨那么鮮艷。
If it is a text, the printing factory will help you change the color to C0, M0, Y0, K100. If it is an illustration or a picture, it is found during the printing process that you can either modify the document or spray more powder (small color blocks are OK), and then reduce the speed. Another way is to change the machine to a UV machine for printing, but the cost is high, and the ink is dark, not as bright as ordinary ink.
在這里,還是啰嗦一下,印刷的黑色,就是K100,但是這個(gè)黑色做大面積的話,印刷出來(lái)不夠黑,有點(diǎn)灰色,在面積比較大的時(shí)候請(qǐng)?jiān)O(shè)置為:C30-40,M0,Y0,K100,印刷出來(lái)顏色飽和,單色加了30的藍(lán),印刷出來(lái)在陽(yáng)光下隱隱泛藍(lán)色,顏色看起來(lái)較黑。全版黑色值設(shè)置:C40,M20,Y20,K100,印刷出來(lái)黑色很有厚度,很有光澤。
In this case, the printed black is K100. However, if the black is large enough, the printed black is not black enough. It is a little gray. When the area is large, please set it to C30-40, M0, Y0, K100. The printed black is saturated. The monochrome is added with 30 blue, and the printed black is faintly blue in the sun. The color looks black. Full version black value setting: C40, M20, Y20, K100. The printed black is very thick and shiny.
可能有人問(wèn),這黑色的顏色設(shè)置小是多小,大又是多大呢,這個(gè)好難把握,我個(gè)人的經(jīng)驗(yàn)是,正文的字,你用K100足夠,如果是標(biāo)題字,就用C30,M0,Y0,K100,面積再大一點(diǎn)點(diǎn)的,可以用C40,M0,Y0,K100,要是滿版黑色,就為了襯托出產(chǎn)品的,就用C40,M20,Y20,K100。
Some people may ask how small and how big the black color is, which is hard to grasp. My personal experience is that K100 is enough for text characters, C30, M0, Y0, K100 for title characters, C40, M0, Y0, K100 for larger ones, and C40, Y0, K100 for full version black characters.
如果你調(diào)色,不知道這個(gè)顏色印刷出來(lái)會(huì)不會(huì)出現(xiàn)背面蹭臟的情況,個(gè)人的意見是,你把4個(gè)顏色的總值控制在250左右就可以了,畢竟這涉及到油墨和面積的大小。
If you mix colors, I don't know whether the back will get dirty when the color is printed. My personal opinion is that you can control the total value of the four colors to about 250. After all, it involves the size of ink and area.
