纸张对印刷成品的色差有什么影响?
作者:admin 来源:http://www.sdhzyw.com 发布时间:2019-5-17 18:21:55 浏览次数:123
印刷品存在色差是多方面的原因造成的,下面济南书刊杂志印刷厂家就给大家说明一下纸张对印刷成品的色差有何影响?
There are many reasons for the chromatic aberration of printed products. Now Jinan magazine printers will explain to you how paper affects the chromatic aberration of printed products.
1. 纸张白度
1. Paper whiteness
影响纸张白度的因素有:① 浆料的白度:更重要的影响因素。
The factors affecting paper whiteness are: (1) whiteness of pulp: the most important factor.
② 染料:选择染料,应使其在测量白度的主波长附近,不影响其反射率,即不影响纸张白度。
(2) Dyes: Choosing dyes should make them near the main wavelength of whiteness measurement without affecting their reflectivity, that is, paper whiteness.
③ 填料:取决于其种类及等级。
(3) Packing: It depends on its type and grade.
④ 涂料:涂料印刷纸的白度由原纸白度、涂料白度、涂布量来确定。
Coatings: The whiteness of coated printing paper is determined by the whiteness of base paper, coating whiteness and coating amount.
白度不同及带有一定颜色的纸张(如有的纸张偏蓝或者偏黄),对印刷墨层的颜色呈现有不同的影响。因此,在实际生产中应尽量选用白度相同的纸张印刷,以减小纸张白度对印刷颜色产生的影响。
Different whiteness and paper with a certain color (such as blue or yellow paper) have different effects on the color rendering of printing ink layer. Therefore, the paper with the same whiteness should be selected as far as possible in practical production to reduce the influence of paper whiteness on printing color.
2. 纸张的平滑度和光泽度

2. Smoothness and Glossiness of Paper

从对印刷品质量的影响来看,纸张的光泽度与印刷品的光泽度之间有着十分直接的关系,无论是何种类型的油墨,印刷品光泽度均随纸张本身光泽度的提高而提高。纸张的光泽度与纸张的着墨效率有着直接的联系,光泽度高的纸张较光泽度低的纸张在纸面以相同墨膜厚度时,能获得更高的印刷密度。因此,印刷品光泽与纸张本身光泽之间存在着密切的相关性。
From the point of view of the influence on printing quality, there is a very direct relationship between the gloss of paper and the gloss of printed matter. No matter what type of ink, the gloss of printed matter increases with the gloss of paper itself. The glossiness of paper is directly related to the ink efficiency of paper. Paper with high glossiness can obtain higher printing density when the thickness of ink film is the same as paper with low glossiness. Therefore, there is a close correlation between the gloss of printed matter and the gloss of paper itself.
3. 纸张的油墨接受性能与吸收性能
3. Ink Acceptance and Absorption of Paper
油墨接受性能指纸张表面在印刷过程中,在印刷机上压印瞬间接收转移油墨的能力。它与纸张的三个方面性能紧密相关:纸张表面接受印刷油墨润湿的能力;纸张表面吸收一定油墨组分的能力;纸张表面固定和保留均匀墨膜的能力。而纸张对油墨吸收性能发生在从油墨与纸张接触到完全固化在纸面的一个较长时间内,它与纸张毛细孔对油墨中的低粘度组分的吸收和油墨中某些组分向纸内渗透作用有关。
Ink acceptance performance refers to the ability of paper surface to receive transfer ink instantaneously during printing process on the printing press. It is closely related to three aspects of paper performance: the ability of paper surface to accept wetting of printing ink; the ability of paper surface to absorb certain ink components; and the ability of paper surface to fix and retain uniform ink film. The ink absorption performance of paper occurs in a long time from the contact between ink and paper to the full curing on paper surface. It is related to the absorption of low viscosity components in ink by paper capillary and the penetration of some components in ink into paper.
