Abstract
A two-web, dual purpose printing press and method is provided which can be used to 'make ready' and proof gravure rollers on a first web, and to print a sample using the rollers on a second web and under substantially identical conditions during both operational modes. The press includes an interchangeable gravure roller, a pair of impression rollers, (one associated with each of the webs), and structure for selective shifting of the impression rollers between positions wherein each roller alternately forms a web-receiving and printing nip with the gravure roller. A motion-limiting stop arrangement is provided to insure that the respective impression rollers assume a substantially identical position relative to the gravure roller during the respective operational sequences of the press; in this manner printing conditions are uniform during both proofing and sampling.
