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
Ink supply is too large and the printing ink is not strong
1.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。
1 ink supply is too large, resulting in the layout of the ink layer is too thick, under the pressure of printing, resulting in the spread of graphics and text dot, bold lines without edges and corners, resulting in paste version.
2.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。
2 daily work, we use the ink or too much oil, will increase the oil of the ink, the printing process will make the boundaries between the part of the graphics and text blur caused by paste version.
3.油墨过于稀薄,流动性大,引起网点铺展造成糊版。
3 ink is too thin, liquidity, cause dot spread caused paste version.
4.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。。
4 ink drying oil too much, will make the ink emulsification, so that the ink on the printing plate can not break from the middle, most of them remain in the plate, resulting in a heap..
5.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。
5 in the 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 of adhesion, easy to cause the darkened part of the printing paste version.
