画册印刷色彩偏差如何处理?印刷公司会印刷很多东西，比如画册印刷、小册子印刷、杂志印刷等等。今天要讲的画册印刷，就是以图文并茂和少量文字为主的书刊印刷。画册基本上是用铜版纸印制的，而封面用的是特种纸，画册用的是铜版纸，画册都是用特种纸印制的。

　　How to deal with color deviation in album printing? Printing companies will print many things, such as album printing, brochure printing, magazine printing, etc. Today, we will talk about the printing of picture books, which is based on the combination of pictures and texts and a small number of words. The picture album is basically printed on copperplate paper, while the cover is made of special paper, the picture album is made of copperplate paper, and the picture albums are all made of special paper.

　　这是画册印刷，在印刷过程中，会出现各种各样的问题，如:色彩、排版等。所以今天我们就来一下相册打印颜色的问题吧。如果你想专辑印刷颜色偏差的问题,你需要知道专辑印刷颜色偏差的因素,专辑印刷颜色偏差的因素有:油墨:三个主要的油墨有不同程度的颜色偏差,这将影响整个画面不同程度的颜色偏差。但少量的色差可以从油墨配制中纠正。印刷时要把握油墨的灰平衡，同样数量的黄色，产品中，绿色不产生中性的灰色，它们产生的灰色较浅，较浑浊带有褐色的灰色，而不是真正的灰色。

　　This is album printing, in the printing process, there will be a variety of problems, such as: color, typesetting and so on. So today, let's solve the problem of album printing color. If you want to solve the problem of color deviation in album printing, you need to know the factors of color deviation in album printing. The factors of color deviation in album printing are: Ink: three main inks have different degrees of color deviation, which will affect the color deviation in different degrees of the whole picture. But a small amount of color difference can be corrected from the ink preparation. When printing, it is necessary to grasp the gray balance of the ink. For the same amount of yellow, green does not produce neutral gray in the product. The gray produced by them is lighter, turbid and brown, rather than the real gray.

　　原因是由于油墨的吸收颜色的引入光线不理想(墨水光谱曲线并不理想),也就是说,造成油墨的使用不洁净的,在实际的墨水CMYK空间,得到真正的灰色,需要提高绿色油墨的数量。纸张本身:对打印梯度再现性和色彩再现性的影响较大，纸张的平滑度、吸收率、白度和光泽度也较大。平滑度分为表观平滑度和印刷平滑度。表观平滑度是指纸张表面的水平，它取决于纸张表面的形态，描述了纸张表面的结构特征。纸张的表观光滑度与光泽度有一定的关系，高纸的表观光滑度，其光泽度相对较高。

　　The reason is that the light introduced by the absorption color of the ink is not ideal (the ink spectral curve is not ideal), that is to say, the use of the ink is not clean. In the actual ink CMYK space, the real gray is obtained, and the number of green ink needs to be increased. Paper itself: it has a great influence on the gradient reproduction and color reproduction of printing, as well as the smoothness, absorptivity, whiteness and glossiness of paper. Smoothness is divided into apparent smoothness and printing smoothness. Apparent smoothness refers to the level of the paper surface, which depends on the shape of the paper surface and describes the structural characteristics of the paper surface. There is a certain relationship between the surface smoothness and glossiness of paper. The glossiness of high paper is relatively high.
