Environment-friendly laser anti-counterfeiting printing process

Abstract

The invention relates to an environment-friendly and anti-counterfeiting laser printing technique, which pertains to the field of laser printing. The main point of the invention is that a plain paper is adopted by the technique, when in use, firstly an information layer of pictures and words is directly and continuously printed on the plain paper by a flexographic plate; then a bright layer is printed on the information layer of pictures and words by the flexographic plate, at the same time a laser layer of pictures and words is pressed on the bright layer by a film; the bright layer and the laser layer of pictures and words are solidified; finally with the continuous solidification of the bright layer and the laser layer of pictures and words, pressed films are continuously and immediately peeled off from the paper by a peeling device. The environment-friendly and anti-counterfeiting laser printing technique of the invention has an optimization and improvement on the existing technical process and has the advantages that by adopting the laser printing technique of the invention, printing can be directly processed on the plain paper, industrialized and continuous printing can be realized, and the product printed by the invention can present the effect of node laser. Furthermore, the laser printing technique of the invention is far superior to the products of the prior art in the aspects of practicability, environmental friendliness and economical efficiency.

Description

technical field [0001] The invention belongs to the field of laser printing, in particular to an environment-friendly laser anti-counterfeiting printing process. Background technique: [0002] At present, from the perspective of my country's printing and packaging market, the use of special paper is gradually expanding, especially the use of various laser transfer papers, which has been recognized by more and more users. Today's printing and packaging measurement standards are several indicators such as practicability, environmental protection, anti-counterfeiting, economy, and aesthetics. This is also a research topic that the printing and packaging industry is committed to. The environmental protection performance of laser transfer paper is higher than that of laser composite paper in the past. In view of its high production cost and the lack of flexibility in the production of laser graphics, the production requires a special process, that is, it is all coated transfer, a...

AI Technical Summary

Problems solved by technology

The environmental protection performance of laser transfer paper is higher than that of laser composite paper in the past. In view of its high production cost and the lack of flexibility in the production of laser graphics, the production requires a special process, that is, it is all coated transfer, and its use is first coated. Printing after cloth transfer, the laser layer is under the printing layer, it is easy to lose part of the laser effect, and it is impossible to realize in-line printing production

At present, although laser transfer equipment has also appeared on the market, they are all offline transfer and sheet transfer, and the transfer effect has great limitations. The transfer accuracy is not high, the content is not rich enough, the production efficiency is low, and the process is very cumbersome and relatively high production costs

Products such as paper packaging for medical syringes, tape packaging products, etc. must be used in rolls, so normal continuous production is currently impossible, which increases the limitations of printing applications and the relative increase in production costs

Compared with special laser transfer paper, ordinary paper has incomparable advantages of special paper in terms of practicability, environmental protection and economy. It is only because the existing technology is difficult to realize large-scale industrial continuous printing on ordinary paper, which leads to High production costs
