Appeal No. 1997-2397
Application No. 08/061,286
color output device to print at least two different colors.
More particularly, Appellant indicates at page 3 of the
specification that the position of commands in the black-and-
white software that define the color output for one color
separation is determined, and the commands are changed to
indicate that a color other than black is to be produced.
Claim 1 is illustrative of the invention and reads as
follows:
1. A process for converting black-and-white color
separation information contained in Post-Script
software
to color separation information which can drive a color
output device to print at least two different colors,
said process for converting black-and-white color
separation information comprises determining positions
of commands
in the black-and-white software which define the color
output for the information on one color separation,
changing at least one of the commands to indicate that
a color other than black is produced, and producing color
output information that will effect trapping from said
black-and-white color separation information when said
color output device is driven to produce a color image.
