Multiple monochromatic print cartridge printing method separating distinct colour plane into plurality of fake colour planes to form fake colour image
View Patent ↗A printing method includes the steps of: receiving a color image and separating the color image into a plurality of distinct color planes; dithering a first distinct color plane to obtain dot data for the first distinct color plane; dithering a second distinct color plane to obtain dot data for the second distinct color plane; providing the dot data for the first distinct color plane to a first print head cartridge for printing by a plurality of nozzle rows of the first print head cartridge; and providing the dot data for the second distinct color plane to a second print head cartridge positioned downstream from the first print head cartridge in a direction of print media propagation, the dot data for the second distinct color plane for printing by a plurality of nozzle rows of the second print head cartridge.
1. A printing method, comprising the steps of:
receiving a colour image and separating the colour image into a plurality of distinct colour planes;
separating each distinct colour plane into a plurality of fake colour planes;
arranging the plurality of fake colour planes corresponding to one distinct colour plane into a fake colour image logically comprised of a composite of fake colour planes; and
presenting the fake colour image to a multi-coloured print engine of a print head cartridge having a plurality of nozzle rows for printing.
2. A printing method according to claim 1 , further comprising a step of separating the fake colour image in the multi-coloured print engine to obtain the fake colour planes, generating print data for each fake colour plane, and sending the print data for a first fake colour plane to a first nozzle row of the print head cartridge and sending the print data for a second fake colour plane to a second nozzle row of the print head cartridge different to the first nozzle row.
3. A printing method according to claim 2 , further comprising a step of increasing a speed of print media propagation past the print head cartridge to prevents dots printed by the second nozzle row from landing on dots printed by the first nozzle row.
