  • Apparatus and methods for full-width wide format inkjet printing
    Patent number: 8172363
    Abstract: Apparatus and methods are provided for wide format inkjet printing using conventional piezoelectric inkjet print heads that each print at a native resolution. A plurality of inkjet print heads are disposed in a print head array to print an image on the substrate at the native resolution across an entire width of the substrate without scanning across the width of the substrate. The print head array may be shifted in a direction parallel to the width of the substrate, and the print head array may be used to print images on the substrate in multiple passes to form a composite image having a resolution equal to a multiple of the native resolution. Alternatively, a plurality of print head arrays may be provided, with adjacent print head arrays spaced apart to provide a composite print resolution equal to a multiple of the native resolution.
