Abstract:
A high-resolution color inkjet printing system for applying drops of ink to a printing medium which is periodically advanced through a printzone along a print-medium advance axis; said system comprising:a carriage for moving at a predetermined scanning speed across the printzone along a carriage scan axis; a plurality of color printheads mounted on said carriage, each having multiple nozzles, within each particular one of the printheads said nozzles of that particular printhead being of substantially common size, with adjacent nozzles on each color printhead spaced apart from each other a substantially given distance in said print-medium advance axis, which distance is less than one three-hundred-sixtieth of an inch; and a motor moving said carriage in a forward pass direction as all or at least three, whichever is smaller, of said printheads fire drops of ink on selected pixel rows in a single common swath, wherein a separation distance between adjacent ones of said selected pixel rows is approximately the same as said given distance for said adjacent nozzles.
