摘要： A method for printing a plurality of scan lines with one or more inkjet heads includes receiving at least one scanline; creating, from pixels of said at least one scanline, a plurality of bundles of a predetermined size comprising first bundles and consecutive bundles, said first and consecutive bundles comprising pixels for which nozzles of the one or more inkjet heads have to be fired within a first time period and within a consecutive time period, respectively; and storing said plurality of bundles in a first memory. The method includes transferring said plurality of bundles from first memory to second memory; and repeating until all said pixels are available in the second memory as the first bundles. Nozzles of the one or more inkjet heads are fired in accordance with the first bundles within the first time period and steps repeated for consecutive bundles and associated respective consecutive time periods.

摘要： A method for printing at least a first and a later print job includes receiving a first print job containing first image data of one or more first images to be printed in a printable area and a later print job containing later image data associated with a colour, determining a first sub-area of said printable area where no image of the first images is to be printed, using the first image data; printing the one or more first images in the printable area and at least one first control patch in the first sub-area, using for said at least one first control patch at least one colour representative for the colour associated with the later image data, measuring the colour of the printed at least one first control patch, and using the measured colour of the at least one first control patch for controlling the later print job.

摘要： A digital printing apparatus using liquid toner including a carrier liquid, a dispersing agent and imaging particles. The apparatus includes a first image forming unit for a first colour; a second image forming unit for a second colour, and a substrate support assembly for supporting the substrate during the subsequent transfer of first and second liquid toner from the first and second image forming unit to the substrate. The second image forming unit is arranged downstream of the first image forming unit along the substrate support assembly. The first image forming unit and the substrate support assembly are arranged such that the substrate is compressed in a first nip between the first image forming unit and the substrate support assembly. A control mechanism adjusts the first and/or second pattern to compensate for the increased width of the substrate downstream of the first image forming unit.

摘要： A method for printing with an inkjet head includes: printing with an inkjet head comprising a plurality n of parallel nozzle rows, where n is at least 2; where each nozzle row comprises a plurality of nozzles, where adjacent nozzle rows of the plurality of nozzle rows are shifted with respect to each other; where a distance between two nozzle rows, seen in the printing direction, is d; and where said printing includes: moving the substrate with respect to the inkjet head in the printing direction at a printing speed v′; and firing each nozzle of the plurality of nozzles with a firing frequency f′; where the plurality of nozzle rows are fired at different instants in time, such that the distance d′ between printed rows of dots printed by the two nozzle rows, seen in the printing direction, is larger or smaller than d.
