济南塑料袋凹版印刷工艺介绍!

发布日期:2019-12-03 作者:www.paradoxicals.com 点击:

  塑料包装袋,一般是印上各种塑料薄膜,然后阻隔层和热封层结合成复合薄膜,经切割,形成包装袋产品。其中,印刷是道生产线,也是一个非常重要的工序,衡量一个包装产品的水平,印刷质量是位的。因此,了解和控制印刷工艺和质量是生产软包装的关键。下面济南天津塑胶袋定制厂家将为您普及常用的塑胶袋凹印工艺,希望对您有所帮助!
  Plastic packaging bags are usually printed with various plastic films, and then the barrier layer and the thermal seal layer are combined to form a composite film, which is cut to form a packaging bag product. Among them, printing is the first production line and also a very important process. To measure the level of a packaging product, printing quality is the first. Therefore, to understand and control the printing process and quality is the key to produce soft packaging. Next Jinan Tianjin plastic bag customization factory will popularize the common plastic bag gravure printing technology for you, hope to help you!
  塑料薄膜的印刷工艺主要是凹印。凹印塑料薄膜具有印刷质量高、墨层厚、色彩鲜艳、图案清晰活泼、画面层次丰富、对比度适中、形象生动、立体感强等优点。但凹印也有一些不可忽视的缺点,如印前制版工艺复杂、成本高、周期长、污染严重等。
  The printing process of plastic film is mainly gravure printing. Gravure plastic film has the advantages of high printing quality, thick ink layer, bright color, clear and lively pattern, rich picture layers, moderate contrast, vivid image, strong three-dimensional sense, etc. However, gravure printing also has some shortcomings that can not be ignored, such as complex pre press plate making process, high cost, long cycle, serious pollution and so on.
  凹版印刷工艺有平版印刷和套印两种
  Gravure printing process includes lithography and overprint
  1. 表印刷过程
  1. Table printing process
  所谓表印是指在塑料薄膜上进行印刷,经过制袋等工序后,将印出的文字和印出的文字放在成品的表面上。
  The so-called surface printing refers to printing on the plastic film, and putting the printed text and printed text on the surface of the finished product after bag making and other processes.
  塑料薄膜“表面印刷”是以白色油墨为基色,用来衬托其他颜色的印刷效果。它有以下优点:
  Plastic film "surface printing" is based on white ink, which is used to set off the printing effect of other colors. It has the following advantages:
  塑料白墨与PE和PP薄膜具有良好的亲和力,能提高油墨的附着力。
  Plastic white ink has good affinity with PE and PP film, which can improve the adhesion of ink.
  白色油墨的底色是全反射的,可以使印刷更加丰富多彩。
  The background color of white ink is total reflection, which can make printing more colorful.
  印刷底色可以增加油墨层的厚度,使印刷层更加丰富,并富有压花的视觉效果。
  The printing background color can increase the thickness of the ink layer, make the printing layer richer, and have the visual effect of embossing.

  因此,塑料薄膜表面印刷的彩色顺序一般确定为:白色→黄色→品红→绿色→黑色。
  Therefore, the color sequence of plastic film surface printing is generally determined as: white → yellow → magenta → green → black.
  表面印刷塑料薄膜要求油墨附着力好,并具有相当的耐磨性、耐日晒性、耐霜冻性、耐温性。近年来,一些油墨企业已开发出特殊耐高温蒸煮面印刷醇溶性油墨,耐磨损、耐晒、附着力和色泽光泽都非常优异。
  The surface printing plastic film requires good ink adhesion, and has considerable wear resistance, sun resistance, frost resistance and temperature resistance. In recent years, some ink companies have developed special high temperature resistant alcohol soluble printing ink for steaming and boiling surface printing, which has excellent wear resistance, sun resistance, adhesion and luster.
  2. 在印刷过程
  2. In the printing process
  内印是指利用反像图形印版,将油墨转移到内透明的承印物材料上,使承印物的正面像一种特殊的印刷方法。
  Internal printing refers to a special printing method that uses the image reversal graphic plate to transfer the ink to the transparent substrate material to make the front of the substrate look like.
  为了得到相同的视觉效果表印刷,印刷颜色印刷过程的顺序应该是“打印一张表”的反面,也就是白色油墨背景颜色的印刷,从前面的印刷,白色墨水背景颜色可以每个颜色在挫败中发挥作用。因此,印刷过程中的印刷颜色顺序应为:黑色→绿色→品红→黄色→白色。
  In order to get the same visual effect table printing, the sequence of printing color printing process should be the reverse side of "print a table", that is, the printing of white ink background color. From the front printing, white ink background color can play a role in frustration. Therefore, the printing color sequence in the printing process should be: Black → green → magenta → yellow → white.
