Abstract
A method and apparatus for printing digital ink jet images to be backlit by a light source is provided. Such backlit printing relies upon additional color pigment to be hidden in the white layer to add additional color density to the image as the back light source passes light through the layers. Print heads are divided into a region of multiple single color print head arrays and a region of white and color print region printed over a color print region. Such backlit printing may be used on both first surface printing and second surface printing. When such backlit printing is used, it may not be necessary to divide the print heads exactly in half as one layer may require less print nozzles than the other as the interlacing and or DPIs may vary for the different layers.
