Problems solved by technology

[0003] For example, the laser anti-counterfeiting labels and barcodes in the prior art have the characteristics of simple production and low production cost, but they also have some disadvantages, such as the barcode is simple in shape, and ordinary consumers cannot recognize it by eyes, and need to be scanned by tools. It increases the applicability of anti-counterfeiting
Although laser anti-counterfeiting labels can be identified by eyes, laser anti-counterfeiting labels are easy to make and easy to be imitated

[0036] 1. Create a background color block, create a workspace with an image size of 5cm×5cm in Photoshop, a resolution of 2400dpi, and a color mode of CMYK. Fill foreground color C, M, Y, K dot area rate is 20% respectively. Separate four color channels, perform bitmap processing, output resolution 2400dpi, set halftone screen, frequency to 175LPI, shape to be circular, and screen angles of C, M, Y, and K channels to be 15°, 75°, respectively. °, 90°, 45°. After the setting is completed, it is converted to grayscale mode, and the conversion ratio is 1, forming a color version of four colors of yellow, magenta, cyan and black.

Abstract

The invention belongs to the technical field of printing anti-counterfeit technical and discloses a manufacturing method for printed matter anti-counterfeit mark of combination splicing of grating and image carrier. The manufacturing method comprises the following steps that S1, background color blocks are built, specifically, four channels of the cyan channel, the fuchsine channel, the yellow channel and the back channel are separated to form four color plates of the cyan color plate, the fuchsine color plate, the yellow color plate and the black color plate, and the four color plates are screened; S2, graphic and text information needing to be hidden is manufactured; S3, the graphic and text information needing to be hidden is partitioned to form a part A and a part B; S4, the graphic and text information A is placed into the cyan plate, and the four color plates of the yellow color plate, the fuchsine color plate, the cyan color plate and the black color plate are combined to form a digital image with the hidden graphic and text information; S5, the grating is manufactured according to the background color blocks, specifically, the grating is processed, the graphic and text information B is placed in the explicit-implicit grating, and the explicit-implicit grating with the graphic and text information is formed; and S6, the graphic and text information on the grating and the graphic and text information placed in the digital image are spliced, and the anti-counterfeit mark with the complete hidden information is obtained.

Description

technical field [0001] The invention belongs to the technical field of printing anti-counterfeiting, and relates to an anti-counterfeiting method for combined splicing of gratings and image carriers based on a moiré pattern, in particular to a method for making anti-counterfeiting marks of combined splicing of printed gratings and image carriers. Background technique [0002] Anti-counterfeiting methods usually use barcodes or anti-counterfeiting marks, which are pasted, printed, and transferred on the surface of the target, or on the packaging of the target, or on the accessories of the target, and have anti-counterfeiting marks. Anti-counterfeiting is the prevention of imitation or reproduction with the purpose of deception and without the permission of the owner. [0003] For example, the laser anti-counterfeiting labels and barcodes in the prior art have the characteristics of simple production and low production cost, but they also have some shortcomings. For example, t...
