    Abstract: A laser exposure apparatus for exposing exposure material (6), such as light-sensitive offset printing plates. The apparatus comprises a relatively heavy base member and an optical scanning unit (2) employing a movable mirror for deflecting a laser beam. The base member (1) comprises a substantially semi-cylindrical exposure surface (5), on which the exposure material (6) can be placed. A bridge (7) is arranged above the base member (1), said bridge being displaceable along the base member in the longitudinal direction thereof by means of an advancing device (8), the mirror being placed on said bridge. The advancing device (8) is arranged along one side of the base member, and the bridge is mounted in a completely or almost completely balanced manner relative to the advancing device (8) by means of a counterweight (9) provided on a projecting portion (7') of the bridge (7), the centre of gravity (G) of said counterweight being placed on the other side of the advancing device (8). The bridge (7) can optionally rest on longitudinal supporting surfaces (10', 10'', 10''') on the base member (1). As a result, an increased accuracy is obtained in connection with the exposure of the exposure material.

    Abstract: Method and plant for manufacturing an element intended to store an image to be printed for flat printing, wherein colour accepting surface elements are set, within a printing machine, by pressure and heat onto to the printing roll of a printing machine in accordance to the image, or are removed from a colour acceptor coating of the printing roll. Thereby, the manufacturing of the element for the storage of the image to be printed is substantially simplified and rationalized; the mechanical readjusting operations which were indispensable heretofore are thereby avoided.

    Abstract: A lithographic printing plate suitable for digital imaging by means of laser exposure is described. The plate consists of a substrate having coated thereon a layer or layers having an ink repelling top surface. The top layer contains a unique ink repelling co-polymer of poly(siloxanes) and is subject to thermal decomposition. At least one of the coated layers contains a laser radiation absorbing material to convert light to heat. The heated top layer is loosened or removed during exposure rendering the imaged surface ink accepting. The process requires no wet development step and no wiping. The method is well suited for use with relatively inexpensive and reliable high power diode lasers or ND YAG lasers and can be configured as a flat bed, internal or external drum imager. It is well suited for imaging in a plate setter or directly on press. The material can be precoated on suitable supports or it can be sprayed, painted or coated on a reusable drum, plate or sleeve on press.
