Three-dimensional effect glossing method of offset press

Abstract

The invention discloses a three-dimensional effect glossing method of an offset press. The method includes the following steps that a product needing design of concave and convex space patterns is selected, graphic design software of a computer is utilized for making a manuscript with the needed concave and convex space patterns, the color value of the locations, needing a matte effect, of the patterns in the manuscript is set to be 100 k, and the color value of the rest is set to be 0 k; a CTP for UV printing is used for making formes; a color sequence is designed; each printing unit of the offset press is provided with one forme; oil ink of various colors is added to ink containers according to the sequence of the printing process, and reverse glossing ink is added to the corresponding last ink container in the printing process; a UV lamp in the offset press is turned on; the formes are subjected to sammeld ruck after being registered; and printed products are wholly coated with UV gloss oil through an anilox roller of the offset press. By means of the three-dimensional effect glossing method of the offset press, partial image-text has a high-contrast effect, a high three-dimensional effect is achieved, and printed products are delicate and have high quality.

Description

technical field [0001] The invention relates to a glazing method, in particular to a three-dimensional effect glazing method for an offset printing machine. Background technique [0002] At present, in the field of printing and packaging, in order to reflect the exquisiteness of printed products, the printing process effect is becoming more and more diversified, but for offset printing, due to the principle of lithographic printing, the surface of the printed sheet after printing is determined to be a plane, without concave-convex three-dimensional effect It can be said that if the three-dimensional effect of protrusions or depressions is to be achieved, it must be realized in conjunction with later processes such as embossing and embossing, which not only prolongs the construction period but also increases the process cost, and the process effect of the product is relatively simple. Contents of the invention [0003] The problem to be solved by the present invention is to...

[0002] At present, in the field of printing and packaging, in order to reflect the exquisiteness of printed products, the printing process effect is becoming more and more diversified, but for offset printing, due to the principle of lithographic printing, the surface of the printed sheet after printing is determined to be a plane, without concave-convex three-dimensional effect It can be said that if you want to achieve the three-dimensional effect of protrusions or depressions, you must cooperate with the later processes such as embossing and embossing, which not only prolongs the construction period but also increases the process cost, and the process effect of the product is relatively simple
