Abstract: An apparatus and method for processing a lithographic printing plate include a plate transport for conveying the plate through the apparatus, a plate detector for locating the plate in the apparatus and for determining a plate width, one or more nozzles for depositing developer on the plate, wherein the one or more nozzles are arranged to shuttle over the plate or are arranged as a fixed array that spans at least the width of the plate. The plate detector is coupled to the one or more nozzles to selectively actuate the one or more nozzles that are positioned to deposit developer across the plate area, which results in a significant reduction of developer consumption. In preferred embodiments, the nozzles apply developer in accordance with the image on the plate, which enables an even lower consumption of developer.

Abstract translation: 一种用于处理平版印刷版的设备和方法包括：用于将板传送通过设备的板传送器，用于将板定位在设备中并用于确定板宽度的板检测器，用于在板上沉积显影剂的一个或多个喷嘴， 其中所述一个或多个喷嘴布置成穿过所述板或者被布置为固定的阵列，所述固定阵列至少跨越所述板的宽度。 板检测器耦合到一个或多个喷嘴以选择性地致动一个或多个喷嘴，其被定位成将显影剂沉积在板区域上，这导致显影剂消耗的显着降低。 在优选实施例中，喷嘴根据板上的图像施加显影剂，这使得显影剂的消耗更低。

Abstract: A method of preparing a lithographic printing plate includes the steps printing a liquid on a lithographic support to form a printing area which corresponds to a raster image, wherein the raster image includes a section which has a tone-value from 90% to 100%, and the jetted liquid droplets for this section, on a corresponding part from the printing area on the lithographic support, are contactless with each other.

Abstract: A method according for preparing a lithographic printing plate containing a lithographic image consisting of printing areas and non-printing areas includes the steps of jetting and curing droplets of a first curable fluid on a hydrophilic support thereby forming a printing area of the lithographic image; and jetting and curing droplets of a second curable fluid in a non-printing area of the lithographic image thereby forming a hydrophilic protective layer on the hydrophilic support.
