Abstract
Print jobs call for printing multiple logical pages on the same sheet, using base colorants and an extension colorant, and call for a different number of printing passes of the extension colorant for different logical pages. A first bitmap is created, and a first printing pass prints the first bitmap. The first bitmap is then modified to leave only the extension colorant plane, to create a modified bitmap; and a second printing pass prints the modified bitmap on the same sheet. The modified bitmap is additionally modified by removing printing pixels for the logical pages that do not contain an instruction to perform an additional printing pass of the extension colorant; and an additional printing pass prints the modified bitmap. These printing passes are repeated until no more of the logical pages contain the instruction to perform an additional printing pass of the extension colorant.
