造成彩色设计印刷露白的原因有哪些?
作者:admin 来源:http://www.sdhzyw.com 发布时间:2019-9-28 15:12:51 浏览次数:57

引发印刷露白现象发生的原因多种多样,如纸张吸水性,油墨粘度,印刷压力、纸板上有纸屑、灰尘等等。当然,引发印刷露白的原因不同,那么解决问题的方式自然也不尽相同!今天济南彩色设计印刷的小编就给大家详细的讲解一下造成彩色设计印刷露白的原因!

There are many reasons for the phenomenon of printing bleaching, such as the water absorption of paper, ink viscosity, printing pressure, paper scraps, dust on the cardboard and so on. Of course, the causes of printing exposure are different, so the way to solve the problem is naturally different! Today, the small edition of Jinan color design and printing will give you a detailed explanation of the causes of color design and printing white!

做为印刷人员,如何快速找到印刷露白的解决方向呢?往往造成印刷露白的原因不同,出现的露白也有细微的不同,印刷人员需要学会根据表象去判断造成印刷露白的症结所在,从而快速处理!我们大致可以从下面三个方面来看看。

As a printer, how to quickly find the solution direction of printing exposure? Often causes of printing exposure are different, and there are subtle differences in the appearance of exposure. Printers need to learn to judge the crux of printing exposure according to the image, so as to deal with it quickly! We can roughly look at the following three aspects.

1、先检测未印刷的纸板厚度值,再检查纸板从送纸单元出来后的纸板厚度值,看纸板是否有被送纸轮压溃。如果压溃了先解决纸板压溃的问题,送纸间隙是纸板厚度-0.3mm。

  1. First check the thickness of unprinted cardboard, and then check the thickness of cardboard after it comes out of the feeding unit to see if the cardboard is crushed by the feeding wheel. If crushing first solves the crushing problem of cardboard, the paper feeding gap is cardboard thickness - 0.3mm.

2、以上都无误再增加印刷压力值,压力值不应过大,过大容易产生印刷煳,印刷慢磨损加快。

2. Above all, the printing pressure value should not be too high. It is easy to produce printing press when the pressure value is too large, and the slow wear and tear of printing will be accelerated.

3、检查印刷版压是否正常,可以查看印刷版面是否有足够的油墨量。印刷版硬度实地版适合在34-36度。

3. Check whether the printing press is normal, you can check whether the printing plate has enough ink. The hardness of the printing plate is suitable for the field version at 34-36 degrees.

如果印刷油墨粘度正确,印刷版、网纹辊良好还是出现印刷露白现象,主要调整方向以油墨工艺为主导,印刷压力切勿一直加大,可以继续提高油墨粘度,及油墨的渗透性,也可以将印刷机调整为隔张送纸状态进行印刷。

If the viscosity of printing ink is correct, printing plate and screen roller are good or there is a phenomenon of printing bleaching. The main direction of adjustment is ink technology. Printing pressure should not always increase. It can continue to improve the ink viscosity and ink permeability. It can also adjust the printing press to separate sheet feeding for printing.
