Abstract

The invention provides a printing ink used for a package product having pearlescent qualitative sense. The printing ink comprises the following components by weight percentage: 30-60% of a binder, 10-30% of a pearlescent pigment, 20-40% of a solvent, and 0.1-5% of an auxiliary agent; the binder is a complex formulation object of an acrylic acid emulsion and a polyurethane emulsion, the acrylic acid emulsion accounts for 25-50% of total proportion of the printing ink, the polyurethane emulsion accounts for 5-10% of total proportion of the printing ink, weight solid content of acrylic acid in the acrylic acid emulsion is 50-65%, the weight solid content of polyurethane in the polyurethane emulsion is 50-65%; the pearlescent pigment is the pearl powder with particle size of 5-25 [mu]m; a solvent is a mixture of purified water, ethanol and propylene glycol monomethyl ether; an auxiliary agent is a mixture of a dispersing agent, an antifoaming agent, a slow drying agent and a levelling agent. The invention also provides a technology for printing the package product having pearlescent qualitative sense, the printing ink employs a printing technology, the printed package product has obvious pearlescent effect, stability of the printing ink on a machine is good, an ink membrane and a base material have high combination fastness, drying speed is fast, and the technology has the advantages of energy saving and consumption reduction, and environmental friendliness.

Description

[0001] 【Technical field】 [0002] The invention relates to an ink and a printing process thereof, in particular to a packaging product printing process with a pearlescent texture and the printing ink used therefor. [0003] 【Background technique】 [0004] In recent years, green printing has become the main theme of the development of the industry. Among them, water-based ink is favored by more and more printing companies because of its safety, harmlessness, and environmental protection, and its application fields are becoming more and more extensive. [0005] The printing process of pearlescent printing is basically the same as that of traditional water-based ink printing. Pearlescent printing is a new type of special glossy printing that has been popular in packaging and anti-counterfeiting printing in recent years. Transparent ink, silver glitter refracts through the ink layer to produce a pearlescent effect like pearl luster. This kind of printed matter has two major charac...
