一個印刷公司，里面會印刷許多東西，例如：畫冊印刷，宣傳冊印刷，雜志印刷等等。今天來講一下畫冊印刷，就是以圖片及少量文字展現(xiàn)為主的書刊印刷。畫冊根本上是銅版紙印刷而成的，還有采用封面特種紙，內(nèi)頁銅版紙的畫冊，也有全部采用特種紙印刷的宣傳冊。
A printing company can print many things, such as picture album printing, brochure printing, magazine printing and so on. Today, let's talk about album printing, which is a book printing with pictures and a small amount of text. The albums are basically printed on copperplate paper. There are also albums with special cover paper and inner copperplate paper. There are also brochures printed entirely on special paper.
這種就是畫冊印刷，在印刷過程中，會呈現(xiàn)各種形形色色的問題，比方：偏色、排版不對等。那我們今天就來處理畫冊印刷偏色該怎樣處置。想要處理畫冊印刷偏色的問題，就要先曉得畫冊印刷偏色的要素，畫冊印刷偏色的要素有：油墨：三原色油墨都存在不同水平的色偏，這對整個畫面都會不同水平地產(chǎn)生色偏影響。但是少量的色偏能夠從油墨配制方面予以糾正。印刷時要把握好所用油墨的灰均衡，等量的黃、品、青并不產(chǎn)生中性灰，它們產(chǎn)生較淡的、較混濁帶有棕色的灰色，而不是真正的灰色。
This is album printing, in the process of printing, there will be a variety of problems, such as color bias, unequal typesetting. So today we'll deal with how to deal with the color bias in album printing. To deal with the problem of color bias in album printing, we must first know the factors of color bias in album printing. The factors of color bias in album printing are: ink: three primary colour inks have different levels of color bias, which will affect the whole picture at different levels. But a small amount of color deviation can be corrected from the aspect of ink preparation. When printing, it is necessary to balance the gray of the ink used. The equal amount of yellow, grade and green does not produce neutral gray. They produce light, turbid and brown gray, rather than real gray.
其緣由是由于上面引見的油墨對色光的不理想的吸收(油墨的光譜曲線不理想)，也就是由所用油墨不純?nèi)瞧鸬模趯嵺`油墨的CMYK空間中，要得到實地灰色，需進步青墨的量。紙張自身:對印刷品階調(diào)再現(xiàn)性和顏色再現(xiàn)性影響比擬大的是紙張的平滑度、吸收性、白度和光澤度。平滑度分為表觀平滑度和印刷平滑度。表觀平滑度指紙張外表的平整水平，它取決于紙張的外表形貌，描繪了紙張外表的構(gòu)造特性。紙張的表觀平滑度與其光澤度有一定的關(guān)系，表觀平滑度高的紙張，其光澤度也相對較高。
The reason is that the ink introduced above is not ideal absorption of color light (the spectral curve of the ink is not ideal), that is, caused by the impurity of the ink used. In the CMYK space of practical ink, in order to get real grey, we need to improve the amount of blue ink. Paper itself: The smoothness, absorbability, whiteness and glossiness of paper have a greater impact on the reproducibility of tone and color of printed matter. The smoothness is divided into apparent smoothness and printing smoothness. Apparent smoothness is the level of paper surface smoothness. It depends on the appearance of the paper, and describes the structure characteristics of the paper surface. The paper's apparent smoothness has a certain relationship with its glossiness. The paper with high apparent smoothness has a relatively high glossiness.
理解了偏色的要素就能夠曉得如何對他停止處置，
Understanding the elements of bias will enable us to know how to stop dealing with him.
1.片子注重的范疇的一局部，無孔(漏光)CMYK的邊角線必需是完整不劃片，無明顯劃痕。證明必需大幅降低，校正義務(wù)。簽署注，造紙，印刷質(zhì)量，交貨時間，工藝請求后，不能懈怠。
1. For a part of the category that the film pays attention to, the corners of CMYK without holes (light leakage) must be complete without scratches and obvious scratches. The proof must be substantially reduced and the obligation to correct it. Signature notes, paper making, printing quality, delivery time, process requirements, can not be slackened.
2.跟單:要留意畫冊印刷色度;版本(CMYK角落線沒有對齊，好是用放大鏡，你能夠看到錯誤)1，2線;留意，沒有明顯的臟點，要指出的是，在任何時間，畫冊印刷工人擦版子印光局部;留意印暗不用要的白色斑點或其他顏色的點，在任何時分擦除;每印刷局部工人將被抽了出來的樣子，你也能夠依照看到的畫冊印刷機運轉(zhuǎn)一段時間，可能是某種顏色的光或任務(wù)繁重的現(xiàn)象。
2. Documents: Pay attention to the chromaticity of album printing; version (CMYK corner line is not aligned, preferably with a magnifying glass, you can see the error) 1, 2 lines; pay attention to, there is no obvious dirty spots, it should be noted that at any time, album printers erase part of the printing plate; pay attention to dark white spots or other color spots, erase at any time; every part of the printing workers will be pumped. When you come out, you can also run the picture album printer for a period of time according to what you see. It may be a phenomenon of light of a certain color or heavy task.
