Abstract: Rendering a color separation wherein diluted digital images are obtained wherefrom consecutive strips are generated having an overlap and wherein the non-overlap zones and overlap zones are halftoned to obtain non-aligned halftone rasters which are then transferred to a print controller of a digital printer for printing the color separation.
Abstract: A method and apparatus for processing a lithographic printing plate precursor, comprising development with a first gum solution and subsequently with a second gum solution, wherein both gum solutions are provided in a cascade configuration whereby the second gum solution overflows into the first gum solution and the development is combined with mechanical rubbing and/or brushing by one or more flat brushes.
Abstract: A lithographic printing plate precursor is disclosed which includes a support and a coating comprising a photopolymerisable layer including a polymerisable compound, an initiator and a pH sensitive colorant precursor and a protective overcoat layer provided above the photopolymerisable layer including a heat sensitive color-forming IR dye, which upon exposure to heat and/or light forms a print-out image which remains stable or increases during storage of the precursor in light or dark environment.
Abstract: A lithographic printing plate precursor is disclosed which comprises a support, a photopolymerizable image recording layer and an overcoat which comprises a low-molecular radical inhibitor. After image-wise exposure, the plate is heated whereby the radical inhibitor diffuses from the overcoat to the image recording layer, resulting in an increase of the daylight stability of the exposed and heated precursor. Such plate is especially suitable for on-press processing.
