Local large-size fiber letterpress printing system and printed matter thereof

Abstract

The invention provides a local large-size fiber letterpress printing system and a printed matter thereof. The system comprises a fiber ink letterpress printing unit which comprises a letterpress printing roller, an ink roller and a round roller scraper; the system also comprises an ink tank for containing fiber ink; the fiber ink penetrates through the gap between the ink roller and the round roller scraper to form a fiber ink layer; and the fiber ink layer is transferred to a printing material by a bulk boss to form a local fiber ink block. Through the invention, the limit that the existing printer cannot adopt large-size fiber ink is broken through, and a local large-size fiber printed matter is printed and produced.

Description

technical field [0001] The invention relates to a special printing (machine) system and its printed matter, especially a local large-size fiber embossing (machine) system and its printed matter. Background technique [0002] The "structural texture anti-counterfeiting method (CN1274453A)" invented by Chen Mingfa, one of the inventors of the present invention, has obtained Chinese patents, US patents (certificate number US6623041), Russian patents (certificate number 2202127), Korean patents (certificate number 0419436), Vietnamese patents ( Certificate No. 3347) and other international patents (PCT / CN99 / 00102). It selects a material (carrier) with a clear random structure texture (such as the texture formed by adding fibers in the paper) to make an anti-counterfeiting mark; and prints a unique identification number; scans the random structure texture feature information on the mark Collected, used as anti-counterfeiting identification feature information (that is, the basis...

AI Technical Summary

Problems solved by technology

However, in practice, several problems have been encountered: ①The printing or packaging paper that has structural texture (fiber) and meets the requirements must be specially manufactured and used because it is a special special paper and not a general standard paper, which requires a large investment. , high cost, long order cycle, and few varieties, it is difficult to meet the needs of various printing and packaging paper; and the colored fibers in papermaking also cause environmental pollution

②Fibers are distributed all over the paper made, and the fibers are like impurities and dirty spots that destroy the design layout and affect the aesthetics of the printed packaging

③The implementation scheme of pasting self-adhesive texture anti-counterfeiting labels on the product adds a labeling process to the user, which not only increases the cost of use, but also increases the trouble for the user

[0004] However, in practice, it is found that the fiber spreading printing system (CN202378401U) is still not ideal, and its disadvantages are: the printing speed of the fiber spreading process is slow, and the residual fibers are difficult to clean up

[0006] In summary, current printing machines cannot use inks mixed with particles such as large-sized fibers
