摘要:
Systems and methods for aligning preprinted images on a roll of substrate to the moving components of a web press are disclosed. A method in accordance with one embodiment includes determining the speed of the moving components of the press, determining the speed of the web of preprinted images and adjusting the speed of the web of preprinted image to match the speed of the web. In particular embodiments, a press which produces rolls of preprinted material can be modified to change the equivalent cutoff length of the press. In further embodiments, a method of pasting new rolls of material to expiring rolls of material is accomplished by modulating the drive speed of the new roll of material to match the expiring roll of material while at the same time aligning the images on the new roll with the expiring roll.
