Laser pattern impression producing technique

Abstract

The invention relates to a kind of suppress-printing production technology of laser pattern. Install the printed matter and laser membrane on the production line respectively, spread a layer of ultraviolet ray oil on the printed matter surface, make the side with pressed line pattern of the laser membrane coincident with the printed matter, utilize the ultraviolet light to shine the printed matter to solidify the ultraviolet ray oil, the laser transparent membrane is separated from printed matter. In the above-mentioned course, send the cool air into the solidification case, control the temperature of the area between the solidification case printing opacity glass and the printed matter within the range from 30 DEG C to 60 DEG C . This production technology can solidify the ultraviolet ray oil in time, make the laser membrane and printed matter break away from each other automatically, and avoid the problem caused by overheating of the printed matter as bubbling and shape losing of the laser pattern , etc.

Description

technical field [0001] The invention relates to a process for printing a laser anti-counterfeiting pattern, in particular to a production process for embossing a laser pattern on a laser transparent film onto a printed matter. Background technique [0002] Before the present invention was made, people once tried to emboss the laser anti-counterfeiting pattern on the laser transparent film onto the printed matter. The process first coated a layer of ultraviolet light oil (also known as UV oil) on the surface of the printed matter, and then the laser The side of the transparent film with the embossed surface pattern is pressed against the side of the printed matter coated with UV varnish, so that the embossed surface pattern of the laser transparent film is pressed against the UV varnish layer of the printed matter, and then the printed matter is transported into the curing box. Use the ultraviolet light in the curing box to irradiate the printed matter to cure the UV varnish....

AI Technical Summary

Problems solved by technology

The problem in the above process is: In order not to affect the production speed of the entire production line, the UV varnish must be cured in time, so high-intensity ultraviolet rays must be used to irradiate the printed matter. However, the surface of the printed matter will be enlarged after high-intensity ultraviolet irradiation. The increase in temperature often causes problems such as the difficulty of peeling off the laser transparent film and the printed matter, blistering on the surface of the printed matter, deformation or even damage to the laser anti-counterfeiting pattern
