Abstract
The invention relates to an apparatus for imaging surfaces in printing presses, whereby the surfaces to be imaged contains image information of the preceding printing job. The apparatus allows a fast and low-cost regeneration of surfaces carrying image information in printing presses. The apparatus comprises at least one printing form cylinder, a disengageable inking unit, and a movable imaging unit having an image creation unit for applying image information to image and non-image carrying layers on the surface. The imaging unit has an erasing unit preceding the movable imaging unit in the moving direction.

Apparatus for imaging a surface in a printing machine having at least one printing form cylinder, a disengeable inking unit, optionally a disengageable dampening unit cooperating with said printing form cylinder, an optional blanket cylinder cooperating with said printing form cylinder, and a movable imaging unit having an image creation unit for applying image information to image and non-image carrying layers on said surface, said imaging unit having an erasing unit preceding said movable imaging unit in the direction of its motion.
An apparatus for imaging a surface in a printing press having at least one printing form cylinder, a disengageable inking unit, an optional disengageable dampening unit cooperating with the printing form cylinder, an optional blanket cylinder cooperating with the printing form cylinder, a transversing imaging unit having an image creation unit for applying a layer, and an ablation laser for the imaging surface, said imaging unit having an integral erasing unit preceding said image creation unit in the direction of transversing motion.
