Abstract
Xerographic printing system using a Raster Output Scanning (ROS) system incorporating a two wavelength (.lambda.) laser diode source for the ROS and a charge retentive member in the form of a belt or drum structure which is responsive to the two wavelengths. The printing system utilizes a CAD development system in addition to two DAD developments during the second pass for enabling the addition of a gamut broadening color resulting in process color imaging with an enhanced gamut.
