ABSTRACT:
A method of cleaning a mechanism having ink-conducting rollable cylindrical members in a printing unit of a rotary printing press includes spraying solvent into a nip between the ink-conducting rollable cylindrical members, rotating the ink-conducting rollable cylindrical members so as to squeeze the solvent through the nip between the rollable cylindrical members and thereby apply pressure in the nip to an ink/dampening solution mixture on the rollable cylindrical members for loosening the mixture, and removing loosened ink and impurities from the printing unit; and apparatus for performing the method.
