Abstract
PURPOSE: To prevent non-picture parts from being stained in dry lithographic printing, by specifying rubber hardness for an ink roller.
CONSTITUTION: A material of rubber hardness more than 50 is used for an ink roller in contact with a printing plate. Natural rubber, nitrile rubber, butyl rubber, etc. are suitable for use. But, if their rubber hardness is above 50, epoxy and polyacetal resin, stainless steel and copper may be used.
