Abstract
A method for designing a printing plate for mounting on a printing cylinder. An optimal lateral seam path is defined between opposite lateral edges of the plate by applying an energy minimization function. Top and bottom edges of the plate are defined based upon the optimal lateral seam path, preferably with a variable gap therebetween, and the bottom edge is unwrapped from the top edge to define a closed cutting path. The area inside the closed cutting path is wrapped with artwork or portions thereof, and an updated digital graphics file stored. The energy minimization function may include a penalty function, overall seam path length, and seam path amplitude, with weighting factors. For artwork including staggered lanes of step and repeat one-up images, the optimal lateral seam path may extend across each lane through one-up images, steps between adjacent one-up images, or a combination thereof.
