A direct-to-press system using a seamless cylinder coated on the press with a curable polymer. After curing, the surface of the polymer is modified by selective laser radiation to change its affinity to printing ink. The cylinder is used in place of a plate cylinder in an offset press, either conventional or waterless. Since only the surface is selectively modified by the laser, coating thickness and uniformity are of little concern. After printing, the cylinder is cleaned on the press using a cleaning station similar to blanket washers used on presses. Cleaning does not have to be complete since the surface of the cylinder is never exposed to the ink. The system is compatible with existing press designs as it can be mounted in the space currently used to access the plate cylinder for plate changing.
