济南印刷厂家http://www.sdyszb.com印刷品墨层干燥不良对裱胶质量危害极大.影响墨层干燥的因素,除了有油墨的种类、印刷过程中催干剂的用量与类型及印刷、存放间的环境温湿度外,纸张本身的结构也相当重要。如铜版纸与胶版纸其结构不同,则墨层的干燥状况亦有区别。无论是铜版纸还是胶版纸,在墨迹未完全彻底干燥时裱胶,对裱胶质量的影响均是不利的。油墨中所含的高沸点溶剂极易使塑料薄膜膨胀和伸长,而塑料薄膜膨胀和伸长是裱胶后产品起泡、脱层的主要原因。

The printing ink layer drying poor laminating quality harm. Factors affecting the ink layer dry, in addition to type, ink printing process and printing type and amount of drying agent, environmental temperature and humidity storage room outside, the structure of the paper itself is also very important. Such as coated paper and offset paper, the structure is different, the ink layer drying situation is also different. Whether it is coated paper or offset paper, when the ink is not completely dry, the mounting of glue is detrimental to the quality of the mount. The high boiling solvent contained in the ink can easily make the plastic film expand and elongate, while the expansion and elongation of the plastic film is the most important reason for the foaming and delamination of the plastic film after mounting.

数码打稿,即在大批量印刷前,采用数码印刷机印刷一本,作为核对装订顺序、内容、设计效果、图片清晰度和颜色的确认。数码打稿采用碳粉为原料,故颜色较为鲜艳,但颜色不稳定,同台机上午下午输出的同文件打稿颜色都可能有差别。印刷效果与数码打稿相比,印刷颜色相对沉稳,细腻度和图片清晰度稍强于数码打稿,但因数码打稿颜色稳定性差,故在采用数码打稿为色样时,印刷颜色无法跟准数码打稿,一般印刷颜色与数码打稿有10%左右的色差。

济南印刷厂讲解画册印刷中的糊版原因:

Ji'nan printing factory to explain the reasons for paste printing in album printing:

在印刷过程中,我们会经常遇到糊版的现象,糊版是指版面暗调网点扩大变形,互相合并,使暗调的层次没有了,在印品上形成了模糊的印迹,严重的形成了脏斑,产生糊版的原因主要有以下几个方面。

In the printing process, we often encounter the phenomenon of paste version, paste version refers to the layout of darkened dot deformation, merging with each other, make the darkened level is not, in the printing on the formation of fuzzy imprinting, forming a serious spot, causes paste version mainly in the following aspects.

一、供墨量过大和油墨的印刷适应性不强造成的

First, excessive ink supply and printing ink adaptability is not strong

1油墨中燥油过多,会使油墨乳化加重,使印版上的墨层不能从中间断裂,多数留在印版上,造成堆墨,在滚筒挤压力的作用下,使网点逐渐扩大,造成糊版,过量的干燥剂使油墨的黏性增强,对空白部分的附着力增强,容易使印品上的暗调部分引起糊版。

1 ink dryness too much oil, will make the ink emulsification increased, the ink layer on the plate can't from middle fracture, most on the plate, resulting in a stack of ink, roller extrusion under pressure, the network gradually expanded, resulting in excessive drying paste version, so that the ink viscosity enhancement, enhancement of the blank part the adhesion, easy to cause darkened part of printing paste version.

2供墨量过大,造成版面堆积的墨层太厚,在印刷压力作用下,生成了图文网点铺展,线条加粗无棱角,从而引起糊版。

2, the amount of ink is too large, resulting in stacked ink layer is too thick, under the action of printing pressure, generated text, dot spread, the lines bold, no edges and corners, resulting in paste version.

3日常工作中,我们使用调墨油或去黏剂过多,会加大油墨的油性,印刷过程中会使图文部分网点之间界线模糊而引起糊版。

3, daily work, we use inking oil or to remove too much glue, will increase the ink oil, printing process will make the line between text and part of the blurred line and lead to paste version.

4油墨过于稀薄,流动性大,引起网点铺展造成糊版。

4, ink is too thin, liquidity, causing dot spread, resulting in paste version.
