  • Patent number: 4508032
    Abstract: The present invention is related to a gravure press, in particular for indirect gravure printing using a silicon rubber pad, which is first pressed upon the inked and wiped gravure plate to absorb ink and then pressed upon the material to be printed, comprising a mounting plate for a gravure plate, an inking device, a doctor blade and a drive mechanism for the silicon rubber pad, the inking device and the doctor blade. To permit the use of a low-priced plastic plate, the coat thickness of the light-sensitive top coat is equal to the engraving depths; the mounting plate has a microfinished surface, and the doctor blade is rigid and resistant to bending and designed in the form of a straight-edge.
