What are the preparations for printing
install the plate frame on the printing machine, adjust the gap between the plate and the printing, determine the position of the substrate, adjust the service life, and match the ink. The printing ink of plate printing does not penetrate from the hole, but when it is scraped onto the substrate with a rubber scraper, the viscosity of the ink is extremely important. In order to obtain a replica with good image reproducibility, use the ink with a viscosity of Pa.s and a low yield value. In some temperature ranges, the heating and cooling rate can reach more than 30 ℃/min, and the ink with high viscosity has poor transfer performance, easy foaming and wiredrawing, resulting in uneven depth
