Abstract
A machine to facilitate the mounting of flexographic printing plates and for obtaining proofs thereof. The machine includes an impression cylinder supported for rotation at a fixed position, the impression cylinder making contact with printing plates on a plate cylinder and rotating concurrently therewith to print a proof secured to the impression cylinder. The plate cylinder is movable in a vertical plane from a proofing state in which it makes contact with the impression cylinder to a mounting state in which it is separated therefrom. A viewer is provided which is operative in the mounting state to show the operator both the plate he is mounting on the plate cylinder and the image reflected from the proof sheet on the impression cylinder. In order to merge these two images so that the operator sees exactly where to lay the plate on the plate cylinder, means are provided which mechanically interlink the two cylinders to effect a relative adjustment of their angular positions whereby a given point on the plate cylinder is optically coincident with the corresponding point printed on the impression cylinder.
