The printer coater has a frame which comprises ananilox roller, a means to rotate the anilox roller at or near the surfacespeed of the rotating printing surface, a liquid film supply forreplenishing the liquid film on the surface of the anilox roller, and apositioner device to place the printer coater between the on andoff-impression positions. The printer coater apparatus is placed onto atleast one pair of fixed supports mounted on the printing press frame sothat the positioner apparatus can place the printer coater between an onand off-impression position. Spacers of selected widths may be mountedbetween the fixed supports and the interior surfaces of the press frame tocompensate for slightly varying press frame widths associated withdifferent press manufacturers. In the alternative, fixed supports may bemanufactured in different widths and mounted on the interior surface ofthe press frame to avoid the use of spacers. The printer coater isportably liftable into and out of position from the printing press frameand easily transportable to any printing unit of a multiple unit rotaryoffset lithographic printing press or other rotary offset lithographicpresses of the same nominal printing width.
