为什么印刷时会出现飞墨现象?

  有印刷人员反映在印刷东西期间出现某些问题是难免的,比如说飞墨现象的出现便是常有的问题,那么要想解决问题就需要来找到原因。
  Some printers reflect that it is inevitable to have some problems during printing, such as the phenomenon of flying ink is a common problem, so in order to solve the problem, we need to find the cause.
  印刷时,空气的相对湿度低,促进了飞墨的产生。当湿度增加时,电荷减少,飞墨量变小。如果油墨中润版液过多,粘度会急剧下降,墨丝变短,会造成严重的飞墨现象。排斥油墨,造成金属墨辊脱墨。
  When printing, the relative humidity of the air is low, which promotes the generation of flying ink. When the humidity increases, the charge decreases and the amount of flying ink becomes smaller. If the ink version of the solution is too much, the viscosity will drop sharply, the ink becomes short, will cause serious flying ink phenomenon. Repulsive ink, resulting in metal roller deinking.
  墨辊上的墨层越厚,飞墨越大。当纸张性能对油墨附着力不好时,很容易造成墨辊积墨,造成飞墨现象。高分子量油墨的粘合剂在油墨分裂时容易拉长丝,造成飞墨。此外,当墨辊表面凹凸不平,表面干燥开裂时,部分墨层变厚,墨雾量增加,这也是造成飞墨现象的因素之一。如果速度太快,导致墨水飞溅的概率会更高。
  The thicker the ink layer on the roller, the bigger the flying ink. When the paper performance of ink adhesion is not good, it is easy to cause ink roller accumulation, resulting in flying ink phenomenon. High molecular weight ink adhesive in ink splitting easy to elongate wire, resulting in flying ink. In addition, when the surface of the ink roller is uneven, the surface is dry and cracked, part of the ink layer thickens, the amount of ink mist increases, which is also one of the factors causing the phenomenon of flying ink. If the speed is too fast, the chances of ink splattering are higher.
  济南印刷人员在此提醒大家,如果油墨的粘度太大,油墨会在墨辊出口处被拉伸,容易产生飞墨,同时也会造成油墨转移不均匀,使纸张拉毛和粉化,纸张将难以从毯子上剥离,容易压花和掉落。如果粘度太小,墨层分裂不好,容易产生飞墨。同时容易乳化油墨、糊版、扩大网点,影响印品质量。
  Ji 'nan printers here to remind you that if the viscosity of the ink is too large, the ink will be stretched at the exit of the ink roll, easy to produce flying ink, but also cause uneven ink transfer, so that the paper wool and powder, paper will be difficult to peel from the blanket, easy to embossing and falling. If the viscosity is too small, ink layer splitting is not good, easy to produce flying ink. At the same time easy emulsion ink, paste version, expand dot, affect the quality of printing.
  为什么印刷时会出现飞墨现象?以上便是问题的出现原因了,如果想顺利的完成印刷过程并有好的质量,那就注意预防。更多内容就来网站www.xinfengyinshua.cn咨询吧。
