摘要： According to the present invention there is provided a method for lithographic printing comprising the following steps:

preparing a lithographic printing plate by image-wise laser exposing a heat-sensitive non-ablatable wasteless imaging element comprising a compound capable of transferring light into heat and having on a support as top layer a heat sensitive image forming layer comprising a heat-switchable binder which layer becomes more hydrophilic or more hydrophobic under the action of image-wise laser exposure;
mounting said printing element on the press prior to or after the exposure; and
applying a fountain solution and ink,
characterized in that said fountain solution comprises at least one water insoluble compound selected from the group consisting of silica, alumina, titanium oxide, tin oxyde, china clay, smectic clay and zirconium oxide.

摘要： A method for generating a screened reproduction of a contone image comprises the steps of screening the contone image to obtain screened data representative for tones of the contone image and suitable for driving exposure of microdots on a radiation sensitive imaging element; exposing the microdots according to the screened data by at least one set or plurality (p) of radiation beams (b), characterised in that at a point in time (t) at least two radiation beams of the set of radiation beams impinge on a particular microdot (m) of a scanline (l). In particular is described a method for making a lithographic printing plate comprising the abovementioned steps.

摘要： In order to improve the printability of a periodic halftone screen, the amount of growth of the halftone dots in a halftone screen is modulated as a function of tone in a tone selective way that is different for at least two halftone dots. In one embodiment for low densities the number of dots of substantially equal area is modulated, and for high densities the area of dots is modulated. The layout of a photomechanical contact screen and an electronic threshold matrix for obtaining the specific halftone screen is defined.
