Homographic dot printing color and preparation method thereof

Abstract

The invention relates to a printing method of the homographic anti-counterfeiting printing industry, and provides a homographic dot printing color and a preparation method thereof, which are capable of printing laser pattern colors onto paper by the aid of a printing machine and realize an anti-counterfeiting reflection effect. The homographic dot printing color is provided with a homographic bright color, the homographic bright color is arranged at an optional position of a printing dot so as to form the homographic dot printing color, the bright color is generated by an information reflecting layer of a homographic film, and the information reflecting layer of the homographic film is a composite layer which is processed by a laser homographic method and formed in the homographic film. Colors and brightness are overlaid microcosmically, patterns with a laser effect and exquisite patterns printed by a printing machine can be arranged at precise positions and are added with printing colors, large-breadth, high-precision and high-quality printing is realized, paper with novel surfaces and high brightness is manufactured, the appearance is excellent, positioning is accurate, a printing effect and the laser effect are visually detained and stacked to generate novel visual colors, and the homographic dot printing color is a novel anti-counterfeiting type of printing color.

Description

technical field [0001] The invention relates to a printing method in the holographic anti-counterfeiting printing industry, in particular to a holographic dot printing color and a manufacturing method thereof. Background technique [0002] Anti-counterfeiting methods in the prior art include laser anti-counterfeiting and encryption anti-counterfeiting. These anti-counterfeiting methods have their own advantages, such as large amount of information and bright colors, but they also have certain limitations, such as small molding area and high template cost; The printing technology is very advanced, and the colors of the printed patterns are also very rich, but the limitation is that it cannot achieve high-precision anti-counterfeiting such as laser, anti-counterfeiting with a large amount of information and printing rich and bright color patterns, while laser anti-counterfeiting is only limited to the use of transfer. In terms of method, the disadvantage of the transfer method...

[0002] Anti-counterfeiting methods in the prior art include laser anti-counterfeiting and encryption anti-counterfeiting. These anti-counterfeiting methods have their own advantages, such as large amount of information and bright colors, but they also have certain limitations, such as small molding area and high template cost; The printing technology is very advanced, and the colors of the printed patterns are also very rich, but the limitation is that it cannot achieve high-precision anti-counterfeiting such as laser, anti-counterfeiting with a large amount of information and printing rich and bright color patterns, while laser anti-counterfeiting is only limited to the use of transfer. In terms of method, the disadvantage of the transfer method is that it is difficult to locate. Due to the limitation of the format, the format is small, and the printing method cannot achieve the color and effect of laser anti-counterfeiting. Crushed into small pieces and stuck on the paper, the random combination of printing and anti-counterfeiting method is not the pursuit of the present invention because the laser anti-counterfeiting pattern cannot be controlled. The present invention hopes that the laser pattern can be set arbitrarily according to the desired position, and the exquisite The laser pattern is printed by the method of printing machine printing; in addition, the screen printing machine usually uses dot printing, and the precision of dot printing can reach 0.1 cm, but the printed color is different from the effect produced by laser color. The brightness is not comparable in an order of magnitude. The reflected light of the laser pattern constitutes a holographic bright color that is not available in the printing color. How to apply the holographic bright color of the laser color as a printing color to the printing of the printing machine and become the first choice for printing on the printing machine. One of the primary colors in the printing color can be called the primary color of the bright color, which will bring richer color capabilities to the printing, and the amount of information contained in the printed content will greatly increase. How to add laser anti-counterfeiting effect on the printing machine? Printing of pattern colors, how to print laser pattern and ordinary printing pattern on the paper is an urgent problem to be solved by engineers and technicians

Also do not see in the prior art that adopting the method of the present invention to increase the printing color of printing machine printing
