济南印刷厂如何解决纸张掉毛?

来源:http://www.jnurs.com   日期:2020-03-23

  如果纸纤维含量低,就会有毛甚至渣现象,纸毛会附着在毛毯或印版上,造成印版脏,影响转印,直接破坏了印刷品的清晰度,大大降低了印刷质量。一般纸张也有类似的问题,但济南印刷厂要采取合理的方法尽量减少纸张脱落或结渣对印刷的影响。

  If the paper fiber content is low, there will be wool or even slag phenomenon. The paper wool will adhere to the blanket or plate, causing the plate dirty, affecting the transfer, directly damaging the clarity of the printed matter, greatly reducing the printing quality. General paper has similar problems, but Jinan printing factory should take reasonable measures to minimize the impact of paper falling off or slagging on printing.
  济南印刷厂印刷纸粉,造成纸面失毛的原因除了纸张表面强度低所造成的填料和粘合剂的选择不当外,压实也是原因之一。此外,在高速打印的情况下也会产生。
  In addition to the improper selection of fillers and adhesives due to the low surface strength of the paper, compaction is also one of the reasons for the loss of the paper surface. In addition, it can also be generated in the case of high-speed printing.

  纸毛脱粉的故障,一般是由于纸制品质量差造成的。除了建议印刷厂家尽快提高产品质量并要求退货外,济南印刷厂的操作人员还可以根据印刷纸张的具体情况,采取相应的补救措施:
  In general, the paper products are of poor quality. In addition to recommending the printing factory to improve the product quality as soon as possible and require the return of the products, the operators of Jinan printing factory can also take corresponding remedial measures according to the specific situation of the printing paper:
  一、纸,由于原因,如原材料和生产过程在济南印刷印刷过程可能脱粉、羊毛、橡皮布表面的积累,从而影响网站转移,严重时每印刷几千左右必须擦洗毯子,毯子或粘满粉送,印刷产品光泽明显降低。在条件好的情况下,在纸张表面叠印一层白色油墨和水,一般应擦干橡皮布。
  1、 Paper, due to reasons such as raw materials and production process in Jinan printing and printing process may be de powdered, wool, rubber cloth surface accumulation, thus affecting the transfer of the website. In serious cases, every thousands or so of printing must be scrubbed, blankets or pasted with powder to send, and the gloss of printing products is significantly reduced. In good conditions, the paper surface overprint with a layer of white ink and water, generally should be wiped dry blanket.
  二、适当调节油墨的粘度,在油墨中加入适量的粘着剂和稀释剂,降低油墨的粘度,以改善油墨对纸张的粘着性。因为油墨粘度太大也容易使纸张脱落。
  2、 Adjust the viscosity of the ink properly, add a proper amount of adhesive and diluent into the ink, reduce the viscosity of the ink, so as to improve the adhesion of the ink to the paper. Because the ink viscosity is too large also easy to make paper off.
  三、济南印刷机要调整印刷压力,使橡皮滚筒与压印滚筒之间的压力适当降低。或者选择合适的印刷速度,降低速度就好。这样,经过压印后,橡皮布与纸张之间的剥离张力就可以降低。
  3、 Jinan printing machine should adjust the printing pressure to reduce the pressure between the rubber roller and the embossing roller. Or choose the right printing speed, reduce the speed. In this way, after imprinting, the peel tension between the blanket and the paper can be reduced.
  四、容易出现掉纸的情况,如胶版纸、凸版纸、信纸等,在宣传前一定要对纸张进行烘干处理,将纸张表面的纸张、纸粉、纸灰和灰尘、破烂的纸张清理干净。
  4、 It is easy to lose paper, such as offset paper, relief paper, letter paper, etc. before publicity, the paper must be dried, and the paper, paper powder, paper ash, dust and broken paper on the surface of the paper shall be cleaned.
  通过以上四项预防措施,济南印刷厂基本避免了脱落现象对印刷质量的影响。
  Through the above four preventive measures, Jinan printing factory basically avoids the impact of falling off on the printing quality.
