Appeal No. 96-3851
Application No. 08/341,849
The appellant's invention relates to a color printer and
printing method in which both black and color ink pens are
used.
More specifically, a printer server defines color selection
codes for each pixel, encodes the defined color selection
codes, and communicates the codes to the printer such that
true black and processed black both can be used for the same
image and color and black ink both can be printed at the same
pixel. Claim 4 is illustrative of the claimed invention, and
it reads as follows:
4. A method of using a computer printer server to
generate color selection data for an inkjet printer having
black ink and color ink pens capable of printing both black
ink and color ink at a given pixel, the method comprising the
steps of:
the server defining a color selection code for each pixel
of an image to be printed, with the color selection code
designating at least one of the black and color pens for each
printed pixel of the image; and
the server encoding the defined color selection code for
each pixel of the image for communication to the printer,
including the step of encoding of color selection codes for
any said given pixel requiring printing of both black ink and
color ink.
