Abstract
A printing plate is clamped to a plate support by providing the plate support with a magnetic surface and laying a printing plate having opposite edges on that surface. Then, a first strip-like ferromagnetic blade clamp is deposited on the plate so that the first blade clamp is adjacent and parallel to one edge of the plate and a second strip-like ferromagnetic blade clamp is deposited on the plate so that the second blade clamp is adjacent and parallel to the opposite edge of the plate. The magnetic attraction of the blade clamp to the support surface enables the blade clamps to releasably clamp the printing plate to the support surface. Dispensing mechanisms for depositing the blade clamps on, and removing them from, the support surface are disclosed. The invention has particular application to releasably clamping superimposed donor and receptor sheets to the plate cylinder of proofing apparatus.
