Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] Such as figure 1 Shown: On the gravure printing machine, the lower version roller 02 is immersed in the ink tank 01 filled with ink, when the lower version roller 02 rotates, it drives the ink to rotate clockwise and adheres to the lower version roller 02, and the scraper 04 is located at the bottom of the lower version roller 02 On one side, above the ink tank 01, scrape off the excess ink on the lower version roller 02, that is, fill the ink in the cell of the lower version roller 02; print.

[0043] Such as figure 2 , image 3 , Figure 4 Shown: At the initial contact position between the scraper and the dots, that is, at the boundary of the graphic dots, the dots are not dense because the edges of the dots are not uniform, and the ink is directly scraped off with the scraper. During the downward movement of the scraper, it is easy to tak...

Abstract

The invention discloses a gravure plate roller and a sleeve carving process thereof. The gravure plate roller comprises a cylindrical plate roller base body, a layer of copper layer is plated on the cylindrical surface of the plate roller base body, a mesh cavity is engraved on the copper layer, the mesh cavity is formed by combining a plurality of rows of engraving grooves, and the engraving grooves are sequentially arranged axially from the cylindrical surface of the plate roller base body. The gravure plate roller and the sleeve carving process has the beneficial effects that the first notch and the second notch are added, so that the image-text edge mesh cavity is densely filled, the third notch conventional mesh cavity group and the second notch mesh cavity are overlapped, so that themesh cavity is enlarged, when the scraper passes, the mesh cavity is firstly filled with ink, and then ink is scraped normally; firstly, the added first notch and the second notch are filled with ink, then the conventional mesh cavity group is filled with ink, the scraper is contacted with the plate roller from the front of the first notch, so that the scraper is in advance contact with the initial contact position of the plate roller and the ink is carried to fill and scrape the first notch, the second notch and the conventional mesh cavity group, sufficient ink in the mesh at the boundary of the plate roller is ensured, and the quality of the printing product is ensured.

Description

technical field [0001] The invention belongs to the field of printing machine forme roller processing, in particular to a gravure forme roller and a sleeve engraving process thereof. Background technique [0002] In the field of gravure printing, gravure rolls are usually used for printing. On the gravure roll, cells need to be engraved to store ink. A cell wall is formed between adjacent cells. The scraper passes over the cell to scrape off excess ink on the surface of the cell wall, making the cell filled with ink. At the initial contact position between the scraper and the printing roller, that is, at the boundary of the printing roller, if the ink is insufficient, use the scraper to scrape off the ink directly. During the down-running process, it is easy to take away part of the ink in the cells, resulting in insufficient ink in the cells and affecting the printing quality. [0003] Patent document CN202608281U discloses an ultra-fine gravure plate roll, comprising a ...
