Cold-printing process

Abstract

The invention discloses a cold-printing process. The cold-printing process comprises the following steps of: step 1, coating an UV (ultraviolet) curing adhesive at the part needing to be cold-printed on a printing stock by an offset printing plate; step 2, causing the UV curing adhesive coated on the printing stock to be adhesive via an UV curing device; step 3, adjusting the tone and hue of an easily-stripped metal foil film according to the tone needed by a product, and drying the easily-stripped metal foil film via an ultraviolet drying device until the water content is 0; step 4, clamping the printing stock between a rubber cylinder and an impression cylinder, compounding the easily-stripped metal foil film on the printing stock, and tightly adhering the easily-stripped metal foil film by the UV curing adhesive under the pressure of the impression cylinder; and step 5, curing the cold-printed part via an UV curing lamp, and stripping the bottom film, so as to realize the whole cold-printing process. The product can show an extremely abundant colour effects, and is bright in metal effect; the process is simple, and the printing speed is high up to 300 fpm; and the process is suitable for common copper plate paper, coated duplex board with grey back, coated duplex board with white back, white cardboard, aluminium-foil paper and the like, and capable of saving energy, reducing energy consumption, and greatly decreasing printing cost, thus being capable of being widely used.

Description

technical field [0001] The invention relates to the technical field of printed matter surface decoration, in particular to a cold stamping process. Background technique [0002] With the development of social urbanization, technology, and humanization, the printing industry has developed vigorously, and more and more food gift boxes or labels need to be printed, followed by the increase in the use of cold foil printing machines and cold stamping technology Demonstration of complex processes and other issues. [0003] The brand-new cold foil transfer technology uses FOilStar (the star equipment of cold foil transfer technology) installed on the Heidelberg Speedmaster CD102 printing machine in Germany, uses an offset printing plate to coat high-viscosity glue, and transfers the metal foil to the rubber cylinder On the paper between the printing cylinder and the impression cylinder, under the action of pressure, the glued area on the substrate is covered with a metal foil film...
