Abstract: An apparatus for the aftertreatment of photopolymerizable printing plates with means for generating an environment with at least one predetermined condition and a transport device to carry the plates during and for transport of the plates through the apparatus. By uncoupling the transport velocity from the prior process steps, such an apparatus enables in-line aftertreatment. The transport device has multiple orbiting pallets on a type of continuous elevator conveyed at least section-wise through the environment.

Abstract: High volume manufacturing process for flexographic printing plates comprises wash out, drying and post-exposure. During drying the printing plates are transported with a plurality of endless conveyors. The transport speed during drying/post-exposure is lower than the transport speed during wash out such that a storage of flexographic plates can be achieved in the drying and post exposure portion of the process.

Abstract: A device for washing out flexographic printing plates. The device includes a tank, brushes, a first turning roll and a plate conveying mechanism. The tank is for holding a liquid bath. The brushes are adapted to be at least partly immersed in the liquid bath and are for washing front sides of the plates. The conveying mechanism is for conveying the plates in a first conveying direction past the rotatable brushes where the front sides of the plates are cleaned by the brushes and then partially around the first turning roll changing the direction of motion of the printing plates. The turning roll is designed as a cleaning brush which is adapted to clean back sides of the printing plates.

Abstract: This invention relates to an apparatus including pairs of rollers for supporting pressure rolls in a laminating apparatus. The rollers provide the pressure rolls with a uniform pressure distribution across the width of the pressure roll nip.

Abstract: The invention refers to an apparatus for testing the color separations of a multicolor print, comprising a pair of press rollers being mounted in a frame and constituted by rollers which can be lifted off each other, through the roller gap of which an image-bearing element consisting of a support foil with an exposed, photosensitive layer, with a color foil, consisting of a color-bearing foil with a color layer, being placed on this element, is fed such that portions of the color layer adhere to the tacky areas of the image-bearing element. For the solution of this problem to provide an apparatus of the kind by which the testing of the color separations of a multicolor print can be carried out in a simple and rapid manner, a movable frame is provided in which a plurality of pairs of roll bearings for rolls to be unwound and wound up are mounted.
