    Abstract: A variable speed flexographic printer with means to match surface speeds of an ink transfer roll with the associated plate roll. A tachometer measures the rotational speed of a plate roll providing a variable DC input through means which adjust said input proportional to the diameters of the plate and ink transfer rolls providing a proportional variable DC signal to a variable speed DC motor driving the ink transfer roll. A wiper and metering blade is mounted to a block adjustably movable to and from the ink roll depending upon the diameter thereof.
