ABSTRACT:
A method for vertically aligning the color plate cylinders of a press, which prints a two-color image on paper, in order to eliminate the vertical misalignment of the colors in the image printed. The method requires the use of a cylinder positioner that is releasably mounted on the press and involves operating the press to initially print the image, detaching the cylinder positioner from the press, adjusting the position of a positioner stop on the cylinder positioner based on the amount of misalignment in the printed image, reattaching the cylinder positioner, decoupling a color plate cylinder from normal operation, rotating the press's blanket cylinder until it impacts the positioner stop on the cylinder positioner, recoupling the color plate cylinder and then operating the press to correctly print the image.
