Method of preparing printing forms for flexographic printing and a system used in the method

摘要

The present invention concerns a method and a system of preparing a flexographic printing form. It also concerns a preparation table (1) used in the method and system. Printing plates (5) are placed in a plate magazine (2) and the printing plates (5) are delivered in a predetermined order from the plate magazine (2) to the preparation table (1). The printing plates (5) are transported by a transportation means, such as a conveyor belt (3), on the preparation table (1) and further to a printing sleeve (8) or a printing cylinder. During the transportation the printing plates (5) are exposed on the backsides to a light source (7). The printing sleeve (8) is rotated with a speed adapted to the speed of the transportation means in such a way that the printing plates (5) are placed staggered in two or more lanes on the printing sleeve (8). The printing plates (5) placed on the printing sleeve (8) are then imaged, e.g. by laser ablation.
