摘要： The present invention relates to a method of preparing print ready data. The method is adapted for converting first device specific print data for printing a multicoloured print job calorimetrically adapted to a first printing device or set of colorants, e.g. inks or toners, to print data calorimetrically adapted for a second printing device or set of colorants. The method comprises processing the data equally fast or faster than the print speed. The latter may be performed during printing, such that no halts are needed in between print jobs and the printing speed is mainly determined by the speed of the printing engine. The invention also relates to a corresponding system.

摘要： For the reproduction of originals, images are generated on an image carrier, for example by printing. The imaging device that generates the image is usually not capable to cover at once the complete image area on the carrier. If the device is capable to cover the full width of the image area, the image may be generated line by line. Devices not having this capability will generate a first portion of an image line on the carrier. An adjacent second portion of the image line is then generated by another imaging device or after a period of time by the imaging device that generated the first portion. The region where the first and second portion meet on the carrier may cause visual artefacts on the final reproduction due to spatial misregistration of the adjacent line portions. This problem is solved by dividing the image in adjacent sub-images having an overlap zone on the carrier. Within this overlap zone two sub-images will be generated on top of each other for reproducing the original image in that zone, thereby reducing or avoiding the artefacts. According to one method, the resulting optical density of the first and second sub-image is reduced within the overlap zone as the outer edge of the sub-image in the overlap zone is approached. The density reduction may be achieved by reduction of the microscopic density of individual microdots or by reduction of the dot percentage or by a combination of these techniques.

摘要： A method and device for printing a reproduction of an image by using toner particles, in which digital image data of at least two density separations of the image is obtained for forming at least two sub-images. The image data of a first sub-image of the sub-images is provided to a printing station containing toner particles with a particular chromaticity and a particular optical density. Then, the first toner particles are applied in an image-wise manner on an image receiving member for forming a first toner image in correspondence with the image data. Thereafter, on the same printing station and using second toner particles having a chromaticity substantially equal to the particular chromaticity and an optical density substantially equal to the particular optical density, the image data is again provided and the toner particles are again applied for bringing at least one second toner image, corresponding to a second sub-image, on the image receiving member in register with the first toner image.

摘要： A method for controlling the density of microdots produced by a binary or multilevel electrophotographic device. In one example, the toner concentration in a two-component developing system is modified as to keep the toner charge Q/M approximately constant. The toner charge is indirectly assessed. This allows to achieve consistent output densities, irrespective of the environmental parameters, such as relative humidity and temperature.
