ABSTRACT:
A method of and apparatus for rough registration of printing rolls, or plate cylinders, is provided which makes use of a strip gage, preferably formed from a plastic material, and a pointer or indicator to indicate positions on the plate cylinders at each printing station of the press. The printing press is first rough registered in a normal manner for such press and the center lines of the cylinders and of the printing plates on the plate cylinders are aligned. A mark is then made under the pointer in each station on the roll to indicate the rough registration position of the cylinder in the press after registration. The plastic gage strip is then laid about the cylinders either in the press or after the plate cylinders have been removed and the strip and the cylinders are aligned and the station marks originally made under the pointer are transferred from the cylinders to the strip for each station. The largest and the smallest sets of plate cylinders may be used to make an individual gage strip directly and gage strips for sets of plate cylinders of in-between dimensions are then preferably formed by laying out a series of strips between the larger and the smaller cylinder strips and marking the stations on such strips along diagonal lines. Self registering plate cylinders for each set of cylinders are then provided by transferring the station indications for each station onto the cylinder surface of each set of plate cylinders. The plate cylinders can then be remounted in the press at any time for that particular set of cylinders and configuration of press and be immediately placed in rough registration by aligning the cylinder by hand with the pointer indication at that station.
