Method for manufacturing colourless fluorescent ink anti-counterfeiting printing product

Abstract

The invention discloses a method for manufacturing a colourless fluorescent ink anti-counterfeiting printing product. The method comprises the following steps: A. loading a color picture suitable for being printed in a computer; B. opening the picture by using Photoshop software and converting the picture into an RCG mode; C. reversing the picture in the RGB mode; D. creating a file with the size and the resolution the same as those of the image converted by the step A and in the CMYK color mode; E. copying the image information of the file subjected to reversion to an M channel, a Y channel and a C channel of the new file; F. outputting the file of the step E into an M film, a Y film and a C film; G. drying the films into PS formes to be printed; and H. printing the Y forme with green fluorescent ink, printing the M forme with red fluorescent ink, and printing the C forme with blue fluorescent ink. The method has the following beneficial effects: the additive method principle is adopted for printing the printing product, and the colored light principle in the optics is applied in printing, so that a fluorescent image has the color effect with variable continuous tone, and the anti-counterfeiting strength is further improved.

Description

technical field [0001] The invention relates to an ultraviolet fluorescent ink printed product; in particular, it relates to a production method of a colorless fluorescent ink anti-counterfeit printed product. Background technique [0002] Ink anti-counterfeiting technology is a widely used anti-counterfeiting technology in the printing and packaging industry. This kind of anti-counterfeiting technology mainly uses the technology of adding special substances into ordinary ink binders and processing them through special processes to become special printing inks. The characteristics of this type of anti-counterfeiting technology are: simple implementation, low cost, good concealment, bright colors, and convenient inspection. At present, anti-counterfeiting inks mainly include UV-induced fluorescent anti-counterfeiting inks, magnetic anti-counterfeiting inks, heat-sensitive color-changing anti-counterfeiting inks, sunlight-induced color-changing anti-counterfeiting inks, optic...

AI Technical Summary

Problems solved by technology

[0005] The existing shortcoming of anti-counterfeiting printed matter is that the printed image has a single color, such as the colorless fluorescent anti-counterfeiting mark on the RMB, which is only a single yellow-green color; Simple irregular patterns, such as wine labels of major manufacturers, etc.
