2-116 Printer-Specific Differences ENWW
• Render Algorithms — There are no new algorithms for this
command that had twenty different algorithms, of which almost
half of them were monochrome equivalents of color
algorithms. The following table lists the algorithms that are
supported:
The monochrome algorithms are no longer supported since
there are no applications which allow the user to specify that a
color image should sometimes be printed in color and other
times in black and white. The remainder of the algorithms are
not supported as they are not needed for quality WYSIWYG
color printing.
• Download Dither Matrix — Not supported
• Color Lookup Tables — Not supported since it does not
support WYSIWYG color.
• Gamma Correction — Not supported since it does not
support WYSIWYG color.
• Viewing Illuminant — Not supported since it does not support
WYSIWYG color.
• Monochrome Print Mode — This command is only supported
at the beginning of a job, since user applications only support
the choice of monochrome printing of color documents for an
entire document.
