Abstract (en)
[origin: US5159878A] An offset lithographic printing unit (10) in a multi-unit printing press (35) includes a first register adjusting mechanism (80) and a second register adjusting mechanism (84). The first register adjusting mechanism (80) changes the surface speed of the plate cylinder (12) relative to the surface speed of the blanket cylinder (14) when the cylinders (12, 14) are being rotated in a printing operation. The second register adjusting mechanism (84) moves the plate cylinder (12) axially relative to the blanket cylinder (14) when the cylinders (12, 14) are being rotated in a printing operation. A controller (300) operates the first and second register adjusting mechanisms (80, 84) simultaneously when the cylinders (12, 14) are being rotated in a printing operation.
