Gravure printing machine is favored by the public because of its advantages such as easy operation, high degree of printing automation and good quality of finished products. So, what is the whole process of a gravure printing press? What do we need to do to prepare? Let's take a look!
When the gravure press is printing, the plate cylinder inks the whole page, scraping the ink on the blank part of the page with the ink scraper, leaving the ink on the graphic part, and then the paper is transferred to the back of the paper by the embossed cylinder, so that the inked part of the paper is directly transferred to the paper, and the printed matter is piled up or rerolled by the paper receiving part.

After the preparation work before printing is completed, carefully calibrate the plate, check the situation of paper feeding, paper feeding, paper receiving, pushing and pulling rules, and make appropriate adjustments, correct the pressure, adjust the ink supply, and adjust the ink scraper. The adjustment of the ink scraper is mainly to adjust the distance between the ink scraper and the printing plate and the Angle of the ink scraper, so that the pressure of the ink scraper on the layout is uniform and does not damage the printing plate.
