Problems solved by technology

[0003] (1) The hue of products from multiple suppliers is inconsistent; the hue of different batches of products from the same supplier is inconsistent;
[0004] (2) Surface tension and affinity fluctuate, which affects the adhesion fastness of printing ink;
[0005] (3) Compared with silver transfer paper, the price of gold transfer paper is higher; the procurement cycle is longer;
[0006] (4) The white phase of the barcode is difficult to control;
[0007] (5) Print full-page transparent ink (such as matte ink, varnish, etc.) directly on the surface of the gold transfer paper. In order to adjust and compensate the stability of the paper hue, color ink needs to be added to the transparent ink to adjust its hue, which increases the labor intensity. , and the volatility of hue;
[0008] (6) There is a greater risk of excessive VOCs content in gold cardboard and gold laser transfer paper

Abstract

The invention provides yellow pulp printed on a piece of silver card paper or silver laser transfer paper and a preparation method thereof. 20-35 parts by weight of plant rosin resin, 1-2 parts by weight of dispersing agent, 10-20 parts by weight of deionized water, 10-20 parts by weight of ethyl alcohol, 0.3-3 parts by weight of defoaming agent, 2-3 parts by weight of edible red pigment, 6-10 parts by weight of edible yellow pigment, 0.2-0.3 part by weight of sterilizing agent, 0.1-0.2 part by weight of pH regulating agent are mixed and dispersed and then are ground by virtue of a horizontal type sand mill, so that yellow pulp with fineness less than or equal to 10 microns is obtained, and viscosity, detected by adopting a viscosity cup zahn3# at the temperature of 25 DEG C, of the yellow pulp is 50 plus or minus 5 seconds. The yellow pulp printed on the silver card paper or silver laser transfer paper is green and has strong printing adaptability, stable hue, high saturation degree and good transparency and drying performance, is fine in granules and has good gold card paper surface colour and lustre effect when being printed on the silver card paper or silver laser transfer paper.

Description

technical field [0001] The invention relates to printing ink, in particular to a yellow paste printed on silver cardboard or silver laser transfer paper and a preparation method thereof. Background technique [0002] At present, in order to greatly improve the environmental protection grade and aesthetic effect of products, in addition to pursuing the ultimate in printing processing technology, packaging and printing factories are also actively using various high-end packaging materials, such as composite cardboard or laser transfer paper. It is against this background that silver cardboard, silver laser transfer paper, gold cardboard and gold laser transfer paper have been widely used in the field of packaging and printing. Compared with silver cardboard or silver laser transfer paper, gold cardboard and gold laser transfer paper have a stronger visual impact after printing. However, there are many problems in the use of the existing gold cardboard and gold laser transfer ...
