Problems solved by technology

[0004] There are currently some problems in the above process, the main reason is that the printing effect on the color steel plate is prone to ghosting or broken printing, and the main reason is that the cleaning roller on the printing machine cannot clean the redundant or redundant printing on the offset printing roller during the steel plate transmission process. The ink is cleaned, which not only easily causes the ink on the offset roller to reprint or miss printing, but also produces splashes with the offset roller's self-transmission, resulting in secondary printing and dyeing of the ink

Abstract

The invention relates to a coating system of a multilayer printing plate. A cutter frame is arranged in a printer position on a transfer side of a printer offset printing roller, and is hinged with an offset printing roller scraper; a free end of the offset printing roller scraper is leant against the surface of the offset printing roller; and an ink runner is additionally formed in a printer below the offset printing roller, and is leaded to an ink recovery barrel. The coating system is provided with the pattern scraper on the surface of the offset printing roller for effectively preventing reprinting or missing printing of ink on the offset printing roller and instantly recovering the remained ink to prevent the ink from staining on the printer; and when multicolor multilayer printing is adopted, the wrong printing or the repeated printing in multilayer printing is prevented through a mode of appointing a zero point of each printer.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, in particular to a coating system for multi-layer printing plates. Background technique [0002] Printed board is a color-coated board with printed patterns or patterns. It is a new type of home appliance board and building material decoration board that has only been developed abroad in recent years. Printed color-coated board is a product that prints the surface of the galvanized substrate after the coating process to obtain various patterns of patterns. Its appearance is more beautiful and its performance is better than that of the coated board. With the continuous improvement of people's living standards, this product will be more and more popular in the market. In Japan, South Korea and other developed countries, in recent years, they have increased their development efforts in these areas, and they are in the ranks of the technology behind. [0003] The printing of many coated produ...
