  • 如何对印刷版进行检验
  • 本站编辑:杭州诗欣纸制品印刷有限公司发布日期:2022-06-08 13:43 浏览次数:

  纸箱厂大部分的印刷版都是由制版公司提供的,当拿到印刷版后对印刷版进行的检验是重要的内容。如能提早发现印刷版有质量问题就能尽早的退回制版公司,以避免上了印刷机后才发现问题,这样又浪费油墨,又减少印刷机的生产效率,还会造成对客户交货延误等现象。

  那么,究竟该如何对印刷版进行检验呢?主要可以有以下几个步骤:

  一、印刷版的厚度检验,印刷版厚度不均匀就会造成印刷露白或印刷糊等现象,所以可以采用厚度仪进行检测数值是否正确。

  二、印刷版的硬度检验,一般的印刷版硬度可以要求在33-35之间,这个硬度有利于油墨的转移性,好的印刷版油墨转移性应达到80%以上。如印刷版硬度高于42那么油墨的转移性就差,尤其是大色块的印刷版,这样就很容易造成印刷露白。

  三、需要对印刷版进行文字核对,核对方式也很简单,只要在印刷版上涂上印油再用纸张盖上,文字就会转移到纸张上,这样就能很快的对印刷版进行检验,从而避免错误发生。

  总结:印刷版的检验是重要的,如果印刷版要做大实地的印刷,印刷版制作的硬度又比较高,那么这个时候就可以将油墨的粘度调高,用油墨的粘度来弥补印刷版的硬度。所以提前知道问题所在就能在生产前有效地控制。

Most of the printing plates in the carton factory are provided by the plate-making company. It is important to check the printing plates when you get them. If we can find the quality problem of the printing plate in advance, we can return to the plate-making company as soon as possible, so as to avoid finding the problem after the printing machine, which wastes ink, reduces the production efficiency of the printing machine, and causes delivery delays to customers.

So how exactly do you check the printed version? There are mainly the following steps:

First, the thickness of the printing plate test, the uneven thickness of the printing plate will cause the phenomenon of printing white or printing paste, so the thickness meter can be used to detect whether the value is correct.

Two, printing plate hardness test, the general printing plate hardness can be required between 33-35, this hardness is conducive to the transfer of ink, good printing ink transfer should reach more than 80%. If the hardness of printing plate is higher than 42, then the transfer of ink is poor, especially the printing plate of large color blocks, so it is easy to cause the printing of white.

Three, the need for the printed version of the text check, check the way is very simple, as long as the printed version is coated with oil and then covered with paper, the text will be transferred to the paper, so that you can quickly check the printed version, so as to avoid mistakes.

Summary: printing plate inspection is important, if the printing plate to do large field printing, printing plate production hardness is relatively high, then this time you can adjust the viscosity of ink, with the viscosity of ink to make up for the hardness of the printing plate. So knowing the problem in advance can effectively control it before production.
