PDF (Color to B/W?)

[Fred Ridder]

Three follow-up points:

1) If you are creating PDF, you *should* be using the "Adobe PDF"
printer driver. Some people insist that they must use the printer driver
for the actual output device that thei print vendor will be using, but
this is faulty logic and it undercuts the foundation of PDF portability.

2) The Black & White vs. Color printer property setting only exists for
the Adobe PDF printer driver. Drivers for monochrome printers don't
provide the option because they know nothing about color. Drivers
for color printers *might* offer it, but I've never seen one that does;
they all assume that if you're printing to a color printer you want color
output and if you wanted black & white you'd be printing your job
to a cheaper and faster monochrome printer.

3) The Black & White vs. Color printer property setting *will* have
the desired result for TIFF graphics, but will *not* affect EPS or PDF
graphic objects. The reason is that the printer driver never processes
the PostScript code embedded in those graphics; it just passes it
through into the PostScript output stream. If the EPS or PDF contains
color information, that is passed to the PostScript stream unchanged
regardless of the B&W/Color setting.

My opinions only; I don't speak for Intel.
