Maintenance methods of printing press

Pubdate:2020-05-16 15:41:46 Hits:2556

Assuming that the hardness of the cylinder on the printing machine is too large, it may lead to a large increase of step adjustment value, uneven dot density, mechanical ghost, color control failure, uneven dot edge, dot blur, halftone pattern graining, and unsatisfactory printing effect of field color block. Therefore, the printing machine operator must ensure the cleanliness of the drum, ink absorption and softness. When exposed to ultraviolet light or exposed to high temperature and easy to oxidize, the drum will harden. Therefore, it is better to store the rollers in a dark place and keep them away from heat sources and electric motors. Here's a suggestion: wash once a week with decalcified solution or hot water containing 15% vinegar. At the end of the week, wash the roller thoroughly with ink roller cleaner and rinse the drum again on Monday morning. If possible, try to avoid using chemicals on the drum and never use steel pads. It is better to remove all the rollers on the printing press every other quarter for manual cleaning. At the same time, the support and frame of the printing machine should be cleaned. This is a difficult task, but as long as you make efforts, you will be able to see the stains disappear and improve the printing quality.
