Decorative ink printing technology allowing direct gold stamping

Abstract

The invention provides a decorative ink printing process allowing direct gold stamping, and relates to the technical field of printing. The printing process comprises the following steps that (1), platemaking and paper selecting are carried out, a laser gravure printing plate is adopted, and the plate making depth is 35-40 micrometers; (2), printing ink on the paper is carried out, the viscosity of the ink is 21-30 S in order to ensure the quality of ink printing, and finally, a layer of flocking gloss oil is printed; and (3), gold stamping is carried out at 90-125 DEG C, solidifying and drying are carried out at 100-110 DEG C, and the gold stamping speed is 2200-2500 pieces per hour. According to the printing process, the main component of the flocking gloss oil cannot hinder the gold stamping process, so that the product can have a rich color effect and a touch matte effect, gold stamping can be can be directly carried out in the process, the product has the flocking effect, the velvet feeling is caused during touch, the hand feeling is soft and silky, meanwhile, the three-dimensional feeling is strong, the ink layer of the product is firm and not easy to wear, and the grade of the product can be improved after the gold stamping, or the anti-counterfeiting effect is achieved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a decorative ink printing process capable of direct bronzing. Background technique [0002] Printing According to the different types of printing plates used, printing machines can be divided into the following four letterpress printing machines. Letterpress printing is a printing method using letterpress printing, and letterpress printing machine is a machine that uses letterpress to complete the printing process. Gravure printing machine. Gravure printing is a printing method that uses gravure printing. A gravure printing machine is a machine for printing with gravure plates. Offset printing press. Lithography is a printing method that uses offset printing. A lithographic printing press is a machine that uses flat plates to complete the printing process. The lithographic plate mentioned here refers to the printing plate in which the graphic part and the blank part are al...

Problems solved by technology

[0009] However, in the prior art, hot stampable varnish must be printed before hot stamping, and the conditions for hot stamping are very high, which brings great constraints to hot stamping. Agents and non-drying oily substances will make hot stamping not old. It is necessary to stick a layer of absorbent paper on the printing plate and press it once to absorb the wax and non-drying oil on the background ink layer. Then carry out hot stamping; it is also necessary to strictly control the amount of red dry oil added to the ink layer on the surface of the substrate, and the test paper should not exceed 0.5%; the additives in the base ink also have many requirements and restrictions

[0010] In the prior art, in order to improve the texture and layering of paper packaging, matt inks and UV snowflake inks are used in printing to enhance the visual effect of the product and improve the grade of the product. However, in actual production, matte inks and UV snowflake inks are used. The ink brings special visual effects, but bronzing has high requirements for the underlying ink, and cannot be directly bronzed on the matte ink layer and UV snowflake ink layer, and requires additional treatment and coating
