<p>In one embodiment of the invention, a scanning carriage (20) in a color inkjet printer houses three identical color pens for printing cyan, magenta, and yellow. A separate array of nozzles (102, 103, 104) is associated with each color ink. The nozzle arrays are such that they scan over the same print area of the medium (18) during a single scan. To prevent the wet ink from one color swath being deposited over or bleeding into the wet ink from another color swath during the same scan, only a section of each nozzle array is used for printing during a single scan such that wet ink of two different colors cannot overlap during a single scan. This technique reduces ink bleed between colors as well as paper cockle. In another embodiment, a single tricolor pen (106) is used where a single nozzle plate contains three nozzle arrays, one for each color. A section of each nozzle array is used during a single scan, as described above, to prevent wet ink of two different colors from overlapping during a single scan. <IMAGE></p> |
