ABSTRACT:
The present invention is directed to a method and apparatus for bonding a printing plate to a flexible endless printing belt passed around and between a plate cylinder and an adjustable cylinder. Marked on the surface of the printing belt are a first reference line perpendicular to a center line of the printing belt and a second reference line parallel to said center line. Set below the transparent plate is a third reference line parallel to the longitudinal reference line. A turned over printing plate is placed on said transparent plate at an intersection of the third and transverse reference lines and has an adhesive on its rear surface. The first marked reference line on the surface of the printing belt is aligned vertically with said transverse reference line. The plate cylinder is rotated to bring the first marked reference line to a position just above said transverse reference line. The transparent plate is moved to bring said printing plate into contact with the printing belt, and the printing belt and the transparent plate are moved first in one direction and then in the other from the position of alignment between the first reference line of the printing belt and the transverse reference line in a synchronized relation with each other to bond the printing plate to the printing belt by adhesive.
