标签印刷制版应该注意什么?

来源:http://www.shengfengyinshua.com/ 日期:2021-02-11 发布人:shengfeng 标签印刷制版注意事项:用柔性版印刷的标签其图文部分主要以实地、线条、文字等为主,所采用的承印材料大都为纸张、铝箔、塑料薄膜、不干胶等。用水溶性或溶剂型油墨印刷吸收性承印材料时,经过红外热风烘干作用,材料会出现抽涨现象,从而影响套印精度,因此,在考虑印刷色序时要慎重,避免发生此类问题。
Notes for label printing and plate making: the graphic part of label printed by flexographic printing is mainly field, line, text, etc., and the printing materials used are mostly paper, aluminum foil, plastic film, self-adhesive, etc. When water-soluble or solvent-based ink is used to print absorbent substrate material, the material will swell after drying by infrared hot air, which will affect the overprint accuracy. Therefore, we should be careful when considering the printing color sequence to avoid such problems.
标签印刷制版含有大面积实地的色版应尽可能地放在靠后的单元中印刷,因为承印物在吸收了大量油墨后再经过红外烘干,实地单元的抽涨变化比其他单元自然要大一些,对印刷过程中套印的影响也较大,若将此类单元放在文字、线条后印刷,或多或少会给套印带来一定的积极影响。如果必须将实地部分放在靠前的色组中印刷,可以有意识地将其上下方向上的补偿稍稍做大一些,以弥补承印材料抽涨所带来的损失,使得套印更加准确一些。
Label printing plate contains a large area of field color plate, should be placed as far as possible in the back of the unit printing, because the substrate after absorbing a lot of ink, and then after infrared drying, the field unit puff change is larger than other units, the impact of overprint in the printing process is also larger, if this kind of unit is placed in the text, line printing, more or less will give overprint belt To have a positive impact. If you have to print the field part in the front color group, you can consciously make the compensation in the up and down direction slightly larger, so as to make up for the loss caused by the substrate material inflation and make the overprint more accurate.

一、陷印
1、 Trapping
在制作柔性版时,一定量的陷印有利于印刷套准,前提是陷印大小合适。标签印刷制版陷印设得过小或是不进行陷印处理,会造成印刷中出现套准不良(有漏白);而陷印设得过大则会在印品边沿出现一个大的轮廓,以至于影响视觉效果,从而影响标签的整体效果。
In the production of flexo, a certain amount of trapping is conducive to printing registration, provided that the trapping size is appropriate. If the trapping is set too small or not, it will cause poor registration (white leakage) in printing; if the trapping is set too large, a large outline will appear on the edge of the printed product, which will affect the visual effect and the overall effect of the label.
二、版式设计
2、 Layout design
由于柔印基本采用卷筒纸进行印刷,尤其是无接缝套筒技术的应用,大大节省了纸张,但有的柔印机并不能实现联机模切,还是需要经过后续加工(裁切等)才能出成品,标签印刷制版因此在对版面进行设就应充分考虑为后续加工留下充足的余量,不应片面考虑节纸率而忽略后续加工的合格率。
Because flexographic printing basically uses web paper for printing, especially the application of seamless sleeve technology, greatly saving paper, but some flexographic machines can not achieve online die cutting, or need to go through subsequent processing (cutting, etc.) to produce finished products, label printing plate making, so in the layout design, we should fully consider leaving sufficient margin for subsequent processing, should not be one-sided consideration Save paper rate and ignore the pass rate of subsequent processing.
