摘要： A method for generating a screened reproduction of an image includes the steps of providing a representation of an original, defining a desired screen dot arrangement for the image, and writing screen dots in a line by line fashion. The representation of an original has input density values representing the grey levels of various locations of the original for a given color separation. Each screen dot is made up of a plurality of line segments whose length and location determines the dot configuration and whose length and location is determined by employing the input density values of the original and the desired screen dot arrangement. The method is characterized in that at least some of the plurality of line segments are shifted from an otherwise generally straight line configuration so as to cause them to conform to a desired overall dot shape.

摘要： A two-stage method for recording a quality enhanced image on a substrate has a preparation and a production stage. In the preparation stage, the digital image file is scanned for adjacent color pairs with different color values. This exhaustive list is processed according to pre-determined criteria per type of output device, creating a sub-list of color pairs that might potentially create artifacts on the recorded image. Several such sub-lists may be created, each per potential output technology to be used. Each sub-list of color pairs is accompanied by modification parameters, indicating the action that needs to be taken in the recording stage, in order to avoid the artifacts and thereby enhance the recorded image quality. In the second, Production stage, this enhancement information, prepared for the actual output device to be used, is used to modify the imaging parameters such as screening parameters, taking into consideration production information such as enlargement.

摘要： A system for loading and clamping one or more plates (18) onto the cylindrical surface (20) of a rotatable drum (10), such as used in a platesetter for printing, and for unloading the plates from the drum. The system is characterized by clamps (16) that are movable over the surface, preferably along circumferential tracks (12), enabling the attachment of multiple plates, end-to-end and/or side-by-side, each plate having any of a wide range of sizes. The clamps (14,16) are preferably of the dynamic type, whereby the clamping force increases with rotational speed. Also disclosed is a method for mounting and unmounting plates, using the movable clamps, such that allows flexible and convenient arrangement of loading- and unloading stations.

摘要： A method for producing a digital screen printing blank usable in a screen printing process, directly from digital information in the computer, in an economical fashion. In a preferred embodiment, a screen (28) is provided with a photosensitive layer (38), and a digitally determined image from a computer is printed on the screen by means of an inkjet printer. Preferably, a flat bed ink-jet imaging system is used so that the screen can be strectched in a frame and directly placed under the ink-jet head (44). The ink (46) used need not have strong colorant, but functions as a UV mask and thus must contain a UV absorbing pigment. The ink is not absorbed into the photosensitive layer, but remains as an undried image (56) on the surface. The ink must remain wet so that it does not spread and therefore gives a sharp image, and so that the UV absorbent material remains concentrated. The solvent of the ink must be chosen so as to assure that it will not affect the screen. The screen is then irradiated with UV, and the areas which have been printed with ink serve to mask the photosensitive layer from the UV light, while those areas having no ink are exposed so that the photosensitive layer is polymerised by the UV. After the UV irradiation stage, the screen is washed so as to remove the ink and the unpolymerised photosensitive layer. Any liquid that is suitable for washing out the unpolymerised photosensitive layer will also wash away the ink. This leaves the screen with only the polymerised areas of the photosensitive layer that create the blocked areas through which the ink will not pass. Thus, the inventive method provides a digitally imaged screen, directly from a digital image in the computer, which can then be used in any conventional screen printing process.

摘要： Internal drum recording apparatus provided with a rotating deflecting element, comprising two (or more) beams of different wavelenghts, which are simultaneously operatable, and optical elements for bringing the two or more beams to a common optical path before they reach the rotating deflecting element. The deflecting element may have dispersing properties such that beams of different wavelengths will leave it at slightly different angles. The beams of different wavelengths may be generated by laser diodes or tunable laser diodes. The apparatus may further comprise a beam combiner to combine the beams generated by the light sources.
