Abstract
Abstract To permit, selectively, continuous printing, for example for wallpaper, wrapping or gift wrap paper, plastic or other foils continuously coated wth adhesive or the like, while additionally permitting use of the machine for printing on substrates, such as paper, which have margins, the plate cylinders, or the web between the plate cylinders can be respectively so aligned or offset with respect to each other that the position of a groove (5, 6) on one plate cylinder, which would result in an unprinted strip of paper, can have printing information, or adhesive or the like applied thereto by a plate on another printing station or, selectively, the other printing station may have its plate adjusted to provide printing information in a second color over the printed information applied by the first plate cylinder. The system can be expanded with multiple cylinders, and may be applied to offset, direct lithographic, raised letter, flexo graphic printing, and the like. For continuous printing, two printing cylinders, preferably adjacent printing cylinder will have the same color ink applied thereto, overlap or adjustment being possible to thereby provide, for example, striped patterns of greater color intensity; multiple printing stations can apply patterns of different colors. The relative adjustment of the printing cylinders can be by way of a clutch (FIGS. 5, 6) or by adjustment of the length of the travel of the web between adjacent printing stations, by web length or register control rollers.
