Printing unit for printing machine, has transfer form formed in such manner and has reduced wetting ability in comparison to printing ink in sections in which transfer form rolls form cylinder in region of clamping channel

摘要

The unit has a printing plate (17) formed on a form cylinder (11) and clamped in a clamping channel (15). A transfer form (19) is designed as a rubber blanket plate or rubber sleeve, and arranged on a transfer cylinder (12) to transmit printing ink on a printing substrate (21). The transfer form is formed in such a manner and has reduced wetting ability in comparison to printing ink in sections in which the transfer form rolls the form cylinder in a region of clamping channel. The transformer form is fastened to the sections by fluoro rubber or by PTFE particle.
