影响包装印刷色彩的因素是什么?

纸张的主要成分为纤维素、胶料、填料等。而油墨的流动部分是连接料,油墨的颜料靠连接料在纸张的表面结膜干燥而附着。
The main components of the paper are cellulose, rubber, filler, etc.. The flow of ink is connected to the material, the ink pigment on the surface of the paper by connecting the dry and attached to the conjunctiva.
纸张和油墨的主要成分均为非对称型的分子,当它们相互接近时,依靠二次结合力使分子在纸张上完成附着。
The main components of paper and ink are asymmetric molecules, when they are close to each other, rely on the two binding force to make the molecules on the paper to complete the adhesion.

现在包装印刷企业的包装装潢印刷品大多使用涂布白板纸、木浆挂面白板纸、普通箱板纸、木浆挂面箱板纸、牛皮纸和白卡纸。由于不同造纸厂的生产工艺的差异,造成纸张的表面白度和平滑度的显著差异。


Now the packaging printing enterprises packaging printing most of the use of coated white paper, white paper, wood pulp Hanging noodles common box board paper, wood pulp Hanging noodles carton, kraft paper and white cardboard. Due to the differences in the production process of different paper mills, the paper makes a significant difference in the whiteness and smoothness of the paper.

因此,印刷机在压印的瞬间,油墨连接料中流动性高的低分子部分被压入纸张较大的孔隙内,连接料开始从油墨中分离。

Therefore, the printing press in the imprint of the moment, the ink connection material in the high mobility of low molecular parts are pressed into the larger pores of the paper, the material began to separate from the ink.
当油墨的颜料含量高,在墨膜内便可形成大量的细小毛细管,这些大量的细小毛细管保留连接料的能力,比纸张表面的纤维间隙吸收连接料能力大得多。
When the ink pigment content is high, the ink film can be formed a large number of these small capillary, a large number of small capillary retention connection material, a much larger capacity than the binder fiber gap of paper surface absorption.
当颜料的含量低,就会出现油墨附着在纸张的表面上,致使连接料大部分进入纸张的空隙之中,造成承印物上的墨膜偏薄,颜料颗粒露,致使更后的色彩不鲜艳。
When the pigment content is low, there will be attached to the ink on the surface of the paper, the binder paper into the most space, causing the ink film substrate is thin, the pigment particles exposed, resulting in the final color is not bright.
