Problems solved by technology

However, printed products must be glazed or coated with wax after cold stamping to protect the stamped text; further, after adopting the offset printing cold stamping process, because the cold stamping glue is in a semi-cured state after coating, it cannot be stacked, and it needs to be processed immediately in the next process. For hot stamping, it is necessary to attach a special unit for cold stamping to the printing machine, and th

Example Embodiment

[0029] Example one:

[0030] See figure 1 , Shown is the process flow chart of the double-reverse upward-lighting mode medium-temperature hot stamping process of the embodiment of the present invention, including the following steps:

[0031] S10: Use the offset printing plate to coat the UV reverse primer on the non-image area of ​​the substrate in an in-line manner, and cure it with a UV curing lamp;

[0032] Compared with traditional hot stamping, the offset printing plate has a short production cycle and is not restricted by the metal plate etching process, so that the final product exhibits a variety of fine line patterns within 0.1-0.2mm.

[0033] S20: Use the offset printing in-line optical seat to coat the UV reverse surface oil on the substrate in a full-page manner;

[0034] S30: The UV reverse primer and UV reverse surface oil applied in the unmapped area generate a repulsive reverse reaction, and are cured by a UV curing lamp to obtain a UV cured substrate; in a specific ap...

Abstract

The invention belongs to the field of gold stamping and discloses an intermediate-temperature gold stamping technology adopting a double pro-cure manner. The intermediate-temperature gold stamping technology adopting the double pro-cure manner comprises the following steps that firstly, the non-image area of printing stock is coated with a UV pro-cure base coat in an online manner with an offset printing forme, and curing is conducted through an UV curing lamp; secondly, the printing stock is coated with a UV pro-cure finishing coat in a full-forme manner through an offset print online varnishing base; thirdly, the UV pro-cure base coat smeared in the non-image area and the UV pro-cure finishing coat generate a repelling background reaction, and curing is conducted through the UV curing lamp; fourthly, a metal foil film is selected according to product needs; and fifthly, the printing stock is placed on a gold stamping machine, a gold stamping copper plate is heated to 70-90 DEG C, the metal foil film and the UV pro-cure varnishing coat on the printing stock tightly adhere to each other under the press of the gold stamping machine, and a base film is stripped off. According to the intermediate-temperature gold stamping technology adopting the double pro-cure manner, the pro-cure technology and the cold gold stamping technology are combined, so that the equipment cost is reduced; and besides, the product produced through the intermediate-temperature gold stamping technology is fine and smooth in line and has strong metal texture.

Description

technical field [0001] The invention relates to a medium-temperature bronzing process in a double reverse glazing mode, which belongs to the field of bronzing. Background technique [0002] With the improvement of people's brochure design, printing, appearance, style and quality requirements, various printing processes have made great progress. Bronzing techniques include hot stamping and cold stamping. [0003] Hot stamping technology refers to the method of using a special metal hot stamping plate to transfer the hot stamping foil film to the surface of the printing material by means of heating and pressure. The hot stamping process requires special equipment, heating devices, metal hot stamping plates, and high energy consumption. Therefore, obtaining high-quality hot stamping effects also means paying higher cost and energy costs; in addition, hot stamping For hot stamping, a hot stamping copper plate must be made first, and the pattern is on the copper plate. Due to t...
