The Daily maintenance of rollers

1. Daily Cleaning

Every day after work or each batch of products to finish the cleaning of cots must be earnest, clean, avoid cots surface layer and ink pigment, resin oxidation to produce a smooth, hard film layer, or plastic roller glass, the impact of ink transmission. Cleaning generally first kerosene, and then gasoline, because kerosene is not volatile, and gasoline volatile, so cleaning can make the rollers clean and dry. In cleaning, pay attention to wash the two ends of the rollers, in general, offset press rollers easy to accumulate ink, knot skin dry solid, and cleaning do not rely entirely on scraping ink, clean cotton will scrape the ink cleaner, and the end of the rollers wash clean.

3. Avoiding compressive deformation

The offset press is comprehensive and uniform when the press is running normally, so it does not occur in some parts of the sag. Offset printing equipment After a long time downtime, so that the rollers are pressed in a fixed position, this has the possibility of producing local sag, so if the downtime is long or encounter holidays, it is best to put the roller down to the ink roller rack, remember not to directly put on the Mesa, in case the glue roller local compression deformation.
