Abstract
In a multi-color rotary printing press equipped with a plate cylinder at each of a plurality of printing stations where a web is to be printed, the rotary positions of the plate cylinders are pre-adjusted to achieve registry of the printing applied at each printing station by setting all the plate cylinders to a respective zero rotary reference position relatively to a frame of the press and then turning each of the second and subsequent plate cylinders out of their zero positions through a respective angle subtended by an arc length calculated by dividing the web length between the first printing station and that at which adjustment is being effected by the circumference of the plate cylinder and subtracting from this quotient the nearest whole number below the quotient. A gauge is provided to facilitate pre-adjustment of the plate cylinders, the gauge being provided with a dial, showing the required adjustment values for the second and subsequent plate cylinders, and a pointer for indicating on a scale the instantaneous value through which the plate cylinder has been turned.
