Technical Field

The invention relates to the technical field of printing, in particular to a mirror-like printing method.

Background

With the continuous development of economy and the continuous improvement of the living standard of people, the requirements of people on the appearance and the glossiness of the outer surface of an article are gradually improved. The mirror-like printing method can meet the requirements of people on the outer surface of an article. The mirror-like printing method is to enable the outer surface of the article to have a mirror-like smooth effect by using mirror ink.

The prior mirror-like printing method is mainly characterized in that mirror ink is printed on the back surfaces of Polycarbonate (PC), acrylic or organic glass (PMMA), hard polyvinyl chloride (PVC) and processed Polyester (PET) transparent sheets through screen printing, and after the mirror ink is dried, the mirror-like smooth effect on the transparent sheets can be observed from the front surfaces of the transparent sheets.

However, in the current mirror-like printing method, the adopted PC, PET, PVC and PMMA transparent sheets are difficult to degrade, so that the waste of the articles printed on the surface of the sheets is also difficult to degrade, solid waste is easy to form, and the method is not beneficial to environmental protection; meanwhile, the mirror surface ink is printed on the transparent sheet to form the mirror surface effect, so that the transparent sheet needs to be cut and pasted during packaging and transportation, the transparent plate can be safely transported, the cutting and pasting processing needs to be completed manually, time and labor are wasted, and the working efficiency is low. In addition, the mirror printing ink used in the prior mirror printing imitating method adopts metal particle pigment, and the glossiness and the mirror effect are poor.
