Abstract: There is provided a system or apparatus for washing out flexographic printing plates. The system is presented in two distinct embodiments or aspects. In one embodiment the system is provided with a large number of rotating brushes which are at least partly immersed in a liquid bath.

Abstract: There is provided method for controlling radiation emitting from one or more tubular lamps in an exposure apparatus for exposing a photosensitive element to the radiation. The method involves adjusting an adjustable ballast connected to the one or more lamps thereby adjusting the power received by the one or more lamps, wherein adjusting the ballast of the one or more lamps is based on the actual temperature and radiation of the one or more lamps.

Abstract: A system and method for making an image printing plate and for positioning control of a lithographic printing plate in the system. The system includes a carrier plate for supporting the printing plate for thereby increasing image quality, and a controlled curing device for improved accuracy of curing.

Abstract: A lithographic printing form comprising an ink where said ink comprises a polymer or copolymer having acidic groups where at least one of said groups has been converted to an amide. A method of producing a lithographic printing form comprising the steps of printing upon a substrate with an ink comprising the previously mentioned polymer and drying the substrate. An ink and a process for producing inks comprising a polymer or copolymer with acidic groups, where at least one of said groups has been converted to the corresponding amide; optionally the ink further comprises fatty acids, metals, metal complexes and/or dyes.
