印刷厂家是怎么调配油墨?

文章出处: 人气:发表时间:2018-11-19 11:46

油墨调配也叫配墨或调墨,即调整印刷过程中油墨的印刷适性,或利用色料减色法,用三原色油墨调配出所需色相的油墨,它是印刷过程中不可缺少的一个重要环节。油墨调配是否得当,直接影响印刷品的质量。本文,广州印刷厂家(miacarmina.com)将与大家分享油墨调配的基本原则和几点做法。

  油墨调配的基本原则

  1.浓调淡印

  浓调淡印是指将所需油墨调配得比色样颜色略浓一些,印刷时有意将墨量减少,使之达到色样要求。这是因为油墨色相受墨层厚度影响较大,用同一种油墨进行印刷,当墨层厚度变化时,所呈现的色相也会随之变化,特别是采用胶印快三彩票工艺印刷时,受胶印工艺限制,墨层宜薄不宜厚。

  2.用尽量少的色料品种

  油墨调配的几点做法

  1.油墨印刷适性的调整

  (1)油墨的流动性

  承印物不同,对油墨流动性的要求也不同。比如一种原色油墨,印刷在双涂纸上时,其流动性符合印刷要求,而印在双胶纸上时,就需要增大油墨的流动性,以适应双胶纸的印刷适性。一般情况下,表面光滑、渗透能力较差的承印物,要求印刷油墨的流动性要小,而表面粗糙、渗透能力较强的承印物,要求印刷油墨的流动性要大。

  (2)油墨的干燥速度

  印刷企业需要根据自身的业务特点,选择符合产品要求的电脑配色系统。本文以爱色丽配色软件为例,介绍电脑配色系统的实际用法。通常,企业会将常用的油墨进行细化,包括的油墨颜色主要有黄、品、青、黑、绿、橘黄、深蓝、洋红等。根据实验数据选定干退变化小、稳定性好的油墨作为配色油墨的组成。接到客户对色样颜色的要求后,首先用爱色丽分光光度计将测量的纸张颜色输入到配色系统中,再将标准数值输入配色系统,系统就会自动分析得出几组配色方案。按照系统给出的配色方案,借助展色仪将色样呈现在承印物上,之后测量Lab值,并在标准色差范围内进行调整。结果合格后,按得到的配方配墨,用于实际生产的批量打样。
