ABSTRACT:
Gray scale ink jet printing method and apparatus produce a high quality image having varying color intensities. This is achieved by mixing a colored phase change ink with varying amounts of a clear phase change ink base, thereby producing multiple gray scale levels of each color. The mixing either can be performed prior to placement of the phase change ink in the printer, or can be performed within the printer to produce different levels of color intensity during the printing process.
