济南塑料袋厂家来解释什么叫凹版印刷?

发布日期:2019-10-17 作者:www.jnsuliao.com 点击:

  人们知道袋子这个词,但是与袋子印刷有关的凹版印刷却鲜为人知。 现在我在这里解释什么叫凹版印刷。
  People know the word bag, but the gravure printing related to bag printing is little known. Now I'm here to explain what gravure printing is.
  在15世纪中叶,照相凹版印刷术首先是手工进行的。 用刀手动切割铜板或钢板。
  In the middle of the 15th century, gravure printing was first carried out by hand. Cut the copper plate or steel plate manually with a knife.
  在17世纪初,化学蚀刻被用于凹版印刷版的生产。 具体方法是:先在铜皮表面上涂一层耐酸防腐蜡,然后用锋利的钢针在蜡层上画图,将画线的蜡层破坏掉,使之 下方的钢表面被暴露出来,而下方的腐蚀工艺步骤则与酸性溶液接触以形成凹痕。
  In the early 17th century, chemical etching was used in the production of intaglio printing plates. The specific method is: first, apply a layer of acid resistant anti-corrosion wax on the surface of the copper skin, and then use a sharp steel needle to draw a picture on the wax layer to destroy the wax layer, so that the steel surface below is exposed, and the lower corrosion process steps contact with the acid solution to form a dent.
  19世纪许多技术的发明和应用为凹版印刷生产工艺的巨大变化奠定了坚实的基础。 其中包括:1282发现重铬酸钾具有光敏性;  1839年摄影技术发明;  1839年发现重铬酸钾暴露于物理性质之前和之后;  1864复写纸转移方法; 凹版印刷技术诞生于1890年,1890年在维也纳正式投入生产。该凹版印刷方法使用照相胶片将复写纸作为中间体,完全取代了手工雕刻,极大地提高了制版的质量和速度。 但是,由于工艺特性的限制,当时的凹版印刷仍然只能进行印刷。 低档印刷品和随后的布梅兰制版方法未能从根本上提高凹版印刷的质量。
  The invention and application of many technologies in the 19th century laid a solid foundation for the great changes of intaglio printing production process. Among them: 1282 found that potassium dichromate has photosensitivity; 1839 photography technology invention; 1839 found that potassium dichromate was exposed to physical properties before and after; 1864 copy paper transfer method; gravure printing technology was born in 1890, 1890 officially put into production in Vienna. The gravure printing method uses the photographic film to take the duplicating paper as the intermediate, completely replaces the manual carving, and greatly improves the quality and speed of plate making. However, due to the limitation of process characteristics, gravure printing at that time could only be carried out. The quality of intaglio printing could not be improved by the low-grade printing and the subsequent bremerland process.

  直到电子雕刻凹版印刷工艺出现之前,凹版印刷板不再仅依靠一维变化来反映深度的阴影(凹版印刷方法依赖于单元深度的变化,而布美兰制版方法 电子雕刻凹版的变化取决于单元的表面积和深度的同时变化以反映阴影和阴影,从而可以复制高级工作 基于凹版印刷工艺。
  Until the emergence of electronic engraving and intaglio printing process, the intaglio printing plate no longer only relies on one-dimensional changes to reflect the shadow of depth (the intaglio printing method depends on the change of unit depth, while the braziland printing method electronic engraving and intaglio printing method depends on the simultaneous change of unit surface area and depth to reflect the shadow and shadow, so advanced work can be copied based on intaglio printing Printing process.
  特别是在凹版印刷领域广泛使用计算机技术之后,凹版印刷和印刷技术变得更加强大。 从凹版印刷的角度来看,率先实现无膜技术的胶版印刷工艺仍在大力推动CTP技术的推广,在凹版印刷领域的CTP已成功运行了近十年。 其次,数字打样技术的成功应用,如今,数字打样技术已在凹版印刷领域得到了广泛的接受,并在生产中起着不可或缺的作用。
  Especially after the extensive use of computer technology in the field of gravure printing, gravure printing and printing technology become more powerful. From the perspective of gravure printing, the first offset printing technology to realize film-free technology is still vigorously promoting the promotion of CTP technology. CTP in the field of gravure printing has been successfully operated for nearly ten years. Secondly, the successful application of digital proofing technology, today, digital proofing technology has been widely accepted in the field of gravure printing, and plays an indispensable role in production.
