Embodiment 1

[0052] A gravure printing method that replaces the offset printing reverse printing process, which includes the steps:

[0053] 1. Take the cigarette pack printing as an example. Use the multi-color gravure printing machine to print the graphic information of the cigarette pack. For example, print the background color, "cigarette" and "XIANGYAN" and other graphic information on the cigarette pack, such as figure 2 Shown

[0054] 2. Mix 45 parts of styrene-acrylic acid copolymer, 32 parts of polyester acrylic copolymer, 3 parts of ammonia, and 11 parts of auxiliary agents to prepare a water-based varnish by weight; The aqueous varnish and the mixed solvent of water and alcohol are mixed in a volume ratio of 2:1 to prepare an aqueous varnish solution, the viscosity of the aqueous varnish solution is 14s, and the Ph value of the aqueous varnish solution is 9.0; The water-based varnish solution was printed on the part of the cigarette case by electro-engraving, and finally at 100℃, 11...

Abstract

The invention discloses an intaglio printing method replacing a reverse offset printing process. The method comprises the following steps: an intaglio printing machine performs color printing of graphics and text information on printed matters; a gloss oil printing unit performs gloss oil printing on the printed matters; particles with different sizes and irregular shapes are prepared on a printing plate of a laser engraving plate beforehand; and the laser engraving plate performs matte UV oil printing on the printed matters. The particles with different sizes and irregular shapes are preparedon the printing plate of the laser engraving plate; based on a traditional multi-color intaglio printing machine, the laser engraving plate is matched with matte UV oil to realize a production process of color intaglio printing online gloss oil and matte UV oil printing; and the process realizes printing of color ink, gloss oil and matte oil, achieves the same effects of snowflakes, wrinkles androughness with reverse offset printing, has the advantages of high production speed, high efficiency and low cost, and meanwhile, achieves stable printing quality and obvious roughness impression andhand feeling.

Description

Technical field [0001] The invention relates to the field of printing, in particular to a gravure printing method that replaces the offset printing reverse printing process. Background technique [0002] Offset reverse printing means that after printing the printed product according to the normal color sequence, the primer is printed on the local area where the matte is highlighted. After the primer is cured, the surface oil is applied. When the surface oil and the primer contact, a cohesive rejection reaction will occur. After curing, it produces a matte surface effect. [0003] Offset reverse printing process is mainly used to finish the surface of printed matter, it can produce the visual effect and matte touch similar to the "partial bright and partial matte" of screen printing snow oil and embossing oil. However, the production speed of the offset reverse printing process is slow, the cost of reverse primer and top oil is higher, and the touch and three-dimensional feeling of...
