画册印刷中的偏色问题怎么解决?

来源:http://www.jindingyinshua.com   日期:2019-04-24

一个印刷公司,里面会印刷许多东西,例如:画册印刷,宣传册印刷,杂志印刷等等。今天来讲一下画册印刷,就是以图片及少量文字展现为主的书刊印刷。画册根本上是铜版纸印刷而成的,还有采用封面特种纸,内页铜版纸的画册,也有全部采用特种纸印刷的宣传册。

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.
这种就是画册印刷,在印刷过程中,会呈现各种形形色色的问题,比方:偏色、排版不对等。那我们今天就来处理画册印刷偏色该怎样处置。想要处理画册印刷偏色的问题,就要先晓得画册印刷偏色的要素,画册印刷偏色的要素有:油墨:三原色油墨都存在不同水平的色偏,这对整个画面都会不同水平地产生色偏影响。但是少量的色偏能够从油墨配制方面予以纠正。印刷时要把握好所用油墨的灰均衡,等量的黄、品、青并不产生中性灰,它们产生较淡的、较混浊带有棕色的灰色,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.

其缘由是由于上面引见的油墨对色光的不理想的吸收(油墨的光谱曲线不理想),也就是由所用油墨不纯惹起的,在实践油墨的CMYK空间中,要得到实地灰色,需进步青墨的量。纸张自身:对印刷品阶调再现性和颜色再现性影响比拟大的是纸张的平滑度、吸收性、白度和光泽度。平滑度分为表观平滑度和印刷平滑度。表观平滑度指纸张外表的平整水平,它取决于纸张的外表形貌,描绘了纸张外表的构造特性。纸张的表观平滑度与其光泽度有一定的关系,表观平滑度高的纸张,其光泽度也相对较高。
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够晓得如何对他停止处置,
Understanding the elements of bias will enable us to know how to stop dealing with him.
1.片子注重的范畴的一局部,无孔(漏光)CMYK的边角线必需是完整不划片,无明显划痕。证明必需大幅降低,校正义务。签署注,造纸,印刷质量,交货时间,工艺请求后,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.跟单:要留意画册印刷色度;版本(CMYK角落线没有对齐,好是用放大镜,你能够看到错误)1,2线;留意,没有明显的脏点,要指出的是,在任何时间,画册印刷工人擦版子印光局部;留意印暗不用要的白色斑点或其他颜色的点,在任何时分擦除;每印刷局部工人将被抽了出来的样子,你也能够依照看到的画册印刷机运转一段时间,可能是某种颜色的光或任务繁重的现象。
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.
