Embodiment Construction

[0019] As shown in Figures 1 and 2; the present invention uses the principle of printing color science to achieve the surface effect of white cardboard with gold cardboard through a layered printing process. The process steps are:

[0020] A. Choose white cardboard—B. Print silver ink layer—C. Print transparent yellow and black layer—D. Graphic and text overlapping printing—E. Print varnish.

[0021] A. Choose white cardboard: the surface smoothness of white cardboard is required to be above 35S measured by a Buick smoothness meter, and the weight is 230g / m 2 , the whiteness requirement is not less than 86%. And remove the floating dust on the surface through the electrostatic brush device on the printing equipment.

[0022] B. Printing silver ink layer: Print a layer of high-gloss silver ink layer (2) on the surface of white cardboard (1) to imitate the effect of aluminum foil. The number of engraving lines and engraving depth required for printing plate production are 60-70...

Abstract

The invention relates to the printing technical field, in particular to a photogravure technology providing the white card paper with surface effect of the cold card paper. The printing chromatology principle is applied, so as to print a silver ink layer and transparent yellow ink layer on the white card paper so that the white card paper can have the surface effect of the gold card paper. The invention can not only easily realize the surface effect of the gold card paper wholly or partially on the white card paper, but also can be directly inserted on the normal product printing color class without any extra special treatment, which is highly flexible, high-efficiency, low cost and environment protective.

Description

Technical field: [0001] The invention relates to the technical field of printing, in particular to a gravure printing process for making white cardboard have the surface effect of gold cardboard. technical background: [0002] Gold cardboard has a metallic texture and luster on the surface, which can greatly improve the product grade and aesthetic effect, so it has been widely used in the field of high-end decoration packaging. At present, gold cardboard generally has two kinds of composite gold cardboard and transfer gold cardboard. Because the composite gold cardboard contains aluminum foil, the cost is high, and it is difficult to degrade, and it is easy to pollute the environment after being discarded. Although transfer gold cardboard is green and environmentally friendly, it has large equipment investment, complex and unstable process, and high cost. Invention content: [0003] The purpose of the present invention is to overcome the above technical defects and provi...
