    摘要： A method for preparing a lithographic printing plate includes the steps of—providing a lithographic printing plate precursor including: a support having a hydrophilic surface or which is provided with a hydrophilic layer; and a coating provided on the support and including an image recording layer including hydrophobic thermoplastic polymer particles having an average particle size between about 40 nm and about 63 nm and a hydrophilic binder, the coating further including a pigment present in the image recording layer or in an additional layer of the coating, —image-wise exposing the coating, thereby inducing coalescence of the thermoplastic polymer particles at the exposed areas of the image recording layer; —developing the precursor by applying a gum solution to the coating, thereby removing the non-exposed areas of the image recording layer from the support; and—optionally, baking the developed precursor; wherein the hydrophobic thermoplastic polymer particles have an average particle size between about 40 nm and about 63 nm; the amount of the hydrophobic thermoplastic polymer particles is more than about 70% and less than about 85% by weight, relative to the image recording layers; and the pigment has a hydrophilic surface and provides a visible image after the image-wise exposing and developing with the gum solution. The lithographic printing plate precursor has an improved sensitivity, and the obtained lithographic printing plate exhibits an excellent clean-out, no toning, and a high printing run length.

    摘要： A method for preparing a negative-working lithographic printing plate is provided which comprises the steps of (1) providing a lithographic printing plate precursor comprising on a grained and anodized aluminum support, having a hydrophilic surface, a coating comprising (i) polymer particles which are core-shell particles having a hydrophobic heat-softenable core and a hydrophilic shell and (ii) an infrared light absorbing agent, (2) exposing said coating to heat, thereby inducing coalescence of said polymer particles at exposed areas of said coating, and (iii) developing said precursor by applying a gum solution to said coating, thereby removing non-exposed areas of said coating from said support. According to the above method the printing plates exhibit after ageing an improved clean-out and a reduced background stain, resulting in toning-free printing.

    摘要： A method of lithographic printing is disclosed which comprises the steps of unwinding a web of a flexible lithographic base from a supply spool, the lithographic base having a hydrophilic surface, wrapping the lithographic base around a cylinder of a printing press, applying on the lithographic base an image-recording layer which is removable in a single-fluid ink or can be rendered removable in a single-fluid ink by exposure to heat or light, image-wise exposing the image-recording layer to heat or light, processing the image-recording layer by supplying single-fluid ink, thereby obtaining a printing master, printing by supplying single-fluid ink to the printing master which is mounted on a plate cylinder of the printing press; and removing the printing master from the plate cylinder, preferably by winding up on an uptake spool. Since the image-recording layer can be processed by single-fluid ink, the imaging material is suitable for on-press processing in printing presses wherein no fountain solution is supplied to the plate. The method allows a rapid, fully automatic plate change with reduced press down time.
