Satellite intaglio printing method

Abstract

The invention discloses a satellite intaglio printing method, which is performed according to following steps that a printed material passes through a swing roller in a traction unit from a discharging unit and enters a corona treatment unit for corona treatment after tension achieves a preset state, then the printed material is subjected to ground color printing after entering a single coating unit, a coating drying unit dries the printed material, the printed material attached with ground color enters a satellite intaglio printing unit for four-color printing, then a top drying unit bakes the printed material, the temperature of the dried printed material is reduced by a top water cooling unit, the printed material is subjected to deep line embossing treatment by a deep line embossing unit, and a heating unit is used in the deep line embossing process, so the lines of the printed material are clearer, then the printed material passes through a secondary water cooling unit, the printing embossing process is finished, and the well-printed printed material passes through an edge cutting unit, and is coiled by a large coiling unit and shaped. The satellite intaglio printing method solves the problem that the technical requirements of multicolor and precise overprinting of a direct printing process cannot be met.

Description

technical field [0001] The invention belongs to the technical field of textile printing, and in particular relates to a satellite gravure printing method. Background technique [0002] Existing leather printing is mostly done by thermal transfer printing. The basic process is as follows: the printing film printed by dispersing pigments and the leather harvested into rolls after surface treatment enter the heat transfer machine respectively, and the printing pattern on the high-temperature film will Dye sublimation onto the leather to complete the leather transfer printing. The shortcoming of this printing process is that the ink needs to be printed on the OPP film with a unit-type gravure printing machine first, and then transfer printing on the heat transfer machine. It needs to be divided into two processes. The transfer carrier OPP film in the middle cannot be reused, which is not economical and environmentally friendly, and the speed of thermal transfer printing is low, ...
