Stamping transfer technique for printing equipment

Abstract

The invention relates to an imprinting transfer technology for printing equipment, which solves the problem in the prior art that a clearance between a peeled guide roller and a lower pressing drum is difficult to grasp so as to influence the practical application of the imprinting transfer technology. The invention adopts the technical scheme as follows: in an imprinting transfer system, after ultraviolet curing bright oil or adhesive is printed on a printing substrate, a pressing film is arranged on one surface of the printing substrate provided with the ultraviolet curing bright oil or theadhesive to be pressed with the printing substrate together, then ultraviolet rays irradiate on the pressing film and the printing substrate which are pressed together to cause the ultraviolet curingbright oil or the adhesive to cure, the pressing film near the guide roller of the lower pressing drum is then peeled from the printing substrate, and the printing substrate is a imprinting transfer product. The imprinting transfer technology is characterized in that the clearance between the guide roller and the lower pressing drum is 0.1 mm to 3 mm more than the thickness of the printing substrate pluses the thickness of the pressing film , and the clearance is achieved and controlled by a clearance regulating mechanism. When being adhesive used for ordinary printing, the adhesive is naturally cured in natural environment.

Description

technical field [0001] The invention relates to an embossing process of printing equipment, in particular to a printing embossing process that can emboss the laser pattern pattern on the laser pattern film onto the printing material, or can transfer the metal foil to the printing material by lithographic cold ironing An embossing process such as printing embossing. Background technique [0002] Making laser patterns on printing materials, as an intuitive anti-counterfeiting pattern that consumers can easily identify, is also a new type of decorative pattern, which has been widely used in the packaging and printing industries for a long time. In recent years, the laser pattern imprinting transfer process that uses a laser film to be pressed and formed on a UV-curable varnish, then solidified and shaped, and then peeled off the laser film is similar to the laser pattern of the Chinese patent No. 200420071245.5 developed by the applicant and previously applied for The embossin...

AI Technical Summary

Problems solved by technology

However, whether the peeling effect is ideal when the laminated film is peeled off from the printing material is directly related to the size of the gap between the peeled guide roller and the lower pressing roller. If the gap is too small, the smoothness of the peeling will be poor, and if the gap is too large, the gap under the laminated film will be poor. The printing material will vibrate, which will affect the peeling quality. The difficulty of controlling this gap will affect the practical application of the imprint transfer process.
