ABSTRACT:
The positions of horizontal lines on a layout cylinder of a printing plate mounting and proofing machine are located with automatic compensation for stretch that results from various parameters such as the diameter of a printing cylinder on which the layout will be used, and the thicknesses of the printing plates and printing plate backing. A display of the circumferential displacement of the layout cylinder, as the cylinder is rotated, provides the displacement with the necessary compensation for stretch, rather than the actual cylinder displacement.
