Imprint wiring porous plate printing device

Abstract

The invention discloses an imprint wiring porous plate printing device. The device comprises a porous plate roller; a screen printing plate is positioned on the periphery of the porous plate roller; a color collecting roller is positioned on the inner side of the porous plate roller; an ink transfer system consists of an ink transfer roll, an ink transfer roller, an oscillating ink transportation roll and an ink hopper roll; the imprint wiring porous plate printing device is characterized in that the diameter ratio of the porous plate roller to an imprint roller to the color connecting roller to a color molding roll is 6:2:1:1; the oscillating ink transportation roll oscillates between the ink hopper roll and a first ink transfer roller so as to transfer the ink from the ink hopper roll to the first ink transfer roller; then the first ink transfer roller transfers the ink to the color molding roll by means of the ink transfer roll and the second ink transfer roller which are jointed with each other; the color molding roll is in contact with the color collecting roller so as to transfer the ink to the color collecting roller; the porous plate roller have three plates and three neutral positions and the color collecting roller imprints between the neutral positions and the imprinting roller. The imprint wiring porous plate printing device conducts print by means of cylindrical imprint and has high printing efficiency; when the color collecting roller is applied to complete overprinting and wiring printing, overall wiring, special-shaped wiring and multi-colored overprinting can be completed.

Description

technical field [0001] The invention relates to an embossing type stencil printing device for printing special anti-counterfeiting ink in the field of anti-counterfeiting printing, especially banknotes. Background technique [0002] In order to improve the printing anti-counterfeiting technology level, the banknote printing industry at home and abroad has adopted more than two colors of wiring printing in printing processes such as offset printing, gravure printing and embossing, which has played a positive role in the anti-counterfeiting of banknotes. However, in the field of missing printing technology, the current screen printing technology has not yet realized the wiring and overprinting of two colors or more. The ink part on the printing plate applies a certain amount of pressure and at the same time moves towards the other end of the screen printing plate. During the movement, the ink is squeezed by the scraper from the mesh of the graphic part to the substrate to com...

AI Technical Summary

Problems solved by technology

During the movement, the ink is squeezed by the scraper from the mesh of the graphic part to the substrate to complete the printing. This scrape printing method cannot carry out wiring and overprint printing of more than two colors at the same time.
