Printing technology

Abstract

The invention relates to a printing technology and particularly relates to a six-polychrome printing technology. The printing technology includes the following steps that firstly, a printing ink is printed on a printing stock by a six-color and varnishing printer, secondly, ultraviolet rays emitted by a first group ultraviolet lamp curing lamp are used for illuminating the print ink so that the print ink is subjected to a cross-linking reaction with printed layers, thirdly, ultraviolet rays emitted by a second group ultraviolet lamp curing lamp are used for illuminating the print ink to enable the printed layers to be cured, fourthly, an infrared dryer is arranged to dry the printed layers, and fifthly, and an ultraviolet (UV) polishing device is used for a UV polishing for the dried printed layers. The printing technology has the advantages that by means of the modifications of the printing ink and production process, the problem that the whole printing efficiency is low caused by the slow drying speed of a six-polychrome printing technology in prior art is solved, the production cost is lowered, the production efficiency is improved, and the printing technology has a wide application prospect.

Description

technical field [0001] The invention relates to a printing process, mainly a six-color printing process. Background technique [0002] The printing process of printing six sets of colors on the existing market mainly uses a four-color printing machine. This kind of printing machine can only print four sets of colors at a time, and after printing, it has to wait for drying before printing another two colors, resulting in production efficiency. Seriously low, some six-color printing machines have also appeared on the existing market. These printing machines also have a characteristic of slow drying speed, which affects production efficiency. Contents of the invention [0003] In view of the above shortcomings, the present invention provides a printing process, which solves the problem of drying speed of printing six sets of colors through the transformation of the process and ink. [0004] In order to achieve the above object, the main technical contents of the present inve...
