Abstract
A color gravure printing press of simple construction which is easy to set up and operate, and is therefore economic for use in printing short runs comprises printing members (2) for at least two different colors arranged around a common printing cylinder (1), an impression cylinder (3) including means (11) to hold a sheet of substrate (15) to be printed, and at least as many inking assemblies (4) as there are different color printing members (2) arranged around the printing cylinder (1). Each of the inking assemblies (4) includes a doctor blade (35) movable towards and away from the printing cylinder (1). The press is arranged so that each inking assembly (4) applies ink only to its corresponding printing member (2) and each doctor blade (35) contacts only its corresponding printing member (2), and that the substrate (15) is held in a fixed position on the impression cylinder (3) until it has been contacted and printed by all of the different color printing members ( 2). Consequently it is economically possible to use this simple press as a color proof press for proofing a stream of digital data before preparing a full color set of conventional gravure printing members from it.
