一个印刷公司,里面会印刷许多东西,例如:彩色画册印刷,宣传册印刷,杂志印刷等等。那么彩色画册印刷偏色应该怎么办?下面跟着小编一起来了解一下吧:
A printing company will print many things, such as color album printing, brochure printing, magazine printing and so on. So what should we do in color printing? Let's take a look with the Xiaobian.
想要解决彩色画册印刷偏色的问题,就要先知道彩色画册印刷偏色的因素,彩色画册印刷偏色的因素有:
If you want to solve the problem of color album printing bias, you must first know the factors of color album printing bias, color album printing bias factors are:
1.油墨
1. ink
三原色油墨都存在不同程度的色偏,这对整个画面都会不同程度地产生色偏影响。但是少量的色偏可以从油墨配制方面予以纠正。印刷时要把握好所用油墨的灰平衡,等量的黄、品、青并不产生中性灰,它们产生较淡的、较浑浊带有棕色的灰色,而不是真正的灰色。其原因是由于上面介绍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引起的,在实际油墨的CMYK空间中,要得到实地灰色,需提高青墨的量。
Three primary colors of ink have varying degrees of color deviation, which will affect the whole picture to varying degrees. However, a small amount of color deviation can be corrected from the preparation of ink. In printing, the gray balance of the ink used should be well grasped. The same amount of yellow, grade and green does not produce neutral gray. They produce a lighter, more turbid brown gray, rather than a real gray. The reason is that the ink described above is not ideal absorption of color light (the spectral curve of the ink is not ideal), that is, caused by the use of impure ink, in the actual CMYK space of the ink, to get solid grey, the need to increase the amount of green ink.
2. 纸张本身
2. paper itself
对印刷品阶调再现性和色彩再现性影响比较大的是纸张的平滑度、吸收性、白度和光泽度。
The smoothness, absorbability, whiteness and glossiness of paper have great influence on the tone reproduction and color reproduction of printed matter.

平滑度分为表观平滑度和印刷平滑度。表观平滑度指纸张表面的平整程度,它取决于纸张的表面形貌,描述了纸张表面的结构特性。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。了解了偏色的因素就可以知道如何对他进行处置,

Smoothness is divided into apparent smoothness and printing smoothness. Apparent smoothness is the degree of smoothness of the paper surface. It depends on the surface morphology of the paper and describes the structural characteristics of the paper surface. The apparent smoothness of paper has a certain relationship with its glossiness. The paper with high apparent smoothness has a relatively high glossiness. Knowing the factors of color can know how to deal with him.
