Printing method replacing PP anti-scratch matt film coated on surface with connecting line printing aqueous lacquer

Abstract

The invention belongs to the technical field of paper printing, and particularly relates to a printing method replacing a PP anti-scratch matt film coated on the surface with connecting line printingaqueous lacquer. The method comprises the following steps: S100, preparing folding-resistant base lacquer meeting the printing requirement; S200, preparing wear-resistant surface lacquer meeting the printing requirement; and S300, carrying out connecting line printing lacquer coating on a printing machine provided with two lacquer coating bases, so that the folding-resistant base lacquer and the wear-resistant surface lacquer cover the surface of color paper ink in an overlapped mode. The surface of the printed color paper is coated with the folding-resistant base lacquer, so that the folding-resistant strength of the color paper is improved, then the color paper can not have line bursting and color bursting after being folded for three times at 180 degrees in the forward and reverse directions, and further, the phenomenon of line bursting and color bursting of a color box formed by subsequent die cutting is avoided. The adhesive force of the folding-resistant base lacquer is strong, so that good adhesion is generated for a printing surface and the surface lacquer; and the wear-resistant surface lacquer coats the folding-resistant base lacquer through the printing machine, so thatthe color paper has good surface performance, as well as excellent adhesive force, dyne value, wear resistance, alcohol solvent resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of paper printing, and in particular relates to a printing method of on-line printing with water and oil instead of a PP anti-scratch dumb film coated on the surface. Background technique [0002] Under the impact of today's wave of environmental protection in the world, environment and development have become major issues of general concern to the international community. The continuous growth of my country's packaging industry has given packaging materials a broad space for development. Many materials such as paper, plastic, metal and glass are used in various packaging. However, while packaging brings convenience and benefits to people, it also causes serious harm to the environment in which human beings live. On the one hand, packaging consumes a lot of energy and resources; It is the fourth largest pollution source after water pollution, ocean and lake pollution and air pollution. Therefore, it is of g...
