摘要： A method and a printing system are described capable of rendering more than 2 density levels at the device pixel level using precalculated rectangular screening tiles of finite size that define a spatially repetitive screening operation according to geometric clustered dot screen definitions for first, second and third separation screens that has the following characteristics: (A) the set of at least three separation screens is free of second order moiré; (B) the set of at least three separation screens consists of screens that have no internal moiré and/or screens that have a reduced sensitivity to amplification by process instability of any remaining level of intrinsic internal moiré; and (C) the screens have an optimized and balanced rosette structure leading to a reduction of visible patterning in overlays of the separation screens.

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.
