Improved method for screen printing two-dimensional code platemaking

Abstract

The invention discloses an improved method for screen printing two-dimensional code platemaking. The method comprises the following steps of (1) black and white color inversion treatment is conducted on a two-dimensional code graph, and then platemaking is conducted, so that white ink can penetrate through a blank area and a binary data '0' area in the two-dimensional code graph; and (2) an edge patrolling area and a binary data '1' area in the two-dimensional code graph are complemented in cooperation with the color of a black product, and then the 'white background black code' effect is achieved on the surface of the black product. On the basis of not increasing production procedures and not changing a printing method, printing of the two-dimensional code with the 'white background black code' effect is achieved on the surface of the black product, the two-dimensional code can be recognized by most common code scanning devices, a special portable data collector is not needed, the acceptance cost of factories and users is reduced, and the universalization level of product design is indirectly improved.

Description

technical field [0001] The invention belongs to the technical field of screen printing, and in particular relates to an improved method for screen printing two-dimensional code plate making; the invention can make white two-dimensional codes on the surface of black products easier to be recognized by most common code scanning devices. Background technique [0002] As the corrosion resistance of aircraft airborne equipment continues to improve, along with the emergence of some new anti-corrosion coatings or spraying methods, some black anti-corrosion coating products cannot use nameplates or laser inscriptions for some reason, and in order to ensure two-dimensional To effectively identify the code information, it is necessary to use high-contrast white ink to print the QR code. At this time, there are two problems: [0003] (1).Using the traditional method to directly print white QR codes on the surface of black products. Compared with conventional black QR codes printed on t...

Problems solved by technology

[0003] (1).Using the traditional method to directly print white QR codes on the surface of black products. Compared with conventional black QR codes printed on the surface of other color products, it is equivalent to black and white inverse colors. Most ordinary scanning equipment cannot recognize it and needs to be purchased. The special portable data collector recognizes the two-dimensional code, which leads to the need to add additional scanning equipment in the process of product factory acceptance and user acceptance acceptance. On the one hand, the cost of each link is increased, and on the other hand, it indirectly indicates that the general design level of the product is insufficient. ;

[0004] (2). Print white ink first in the QR code printing area, and then print black QR code on this basis. The effect is consistent with the conventional QR code, but this increases the production process, which is not conducive to mass production of products

If the white ink is directly printed, the display effect of the QR code is reversed. The computer reads 1 in the normal black recognition area of ​​the QR code, and 0 in the white recognition area. If the display effect is reversed, it is equivalent to 1 / 0 recognition reversed. , the content is misidentified or unrecognized
