Abstract:
Apparatus for producing a continuous tone and/or color composite image on a target surface extending in perpendicular lateral and longitudinal directions, said apparatus comprising:a source of digital signals describing said composite image; an imaging head comprised of a plurality of pixel image generators, each image generator being energizable to generate a substantially square pixel image; said imaging head being mounted proximate to said target surface and oriented to offset each of said square pixel images by substantially 450 with respect to said lateral and longitudinal directions; a controller responsive to said digital signals for selectively energizing said image generators and relatively moving said target surface and said imaging head along said lateral and/or longitudinal directions to sequentially image substantially identically shaped pixels onto said target surface to form said composite image, said composite image being formed of multiple longitudinally displaced pixel rows wherein each row is comprised of laterally displaced pixel images; and wherein (1) adjacent pixel images in each row partially overlap and/or (2) pixel images in adjacent rows partially overlap.
