[softwarelist] JPEGs files in PostScript

If I have an Ovation Pro document with colour JPEGs embedded. I am then
outputting to PostScript (PostScript 2 driver) with the colour option not
enabled. The PostScript file is then distilled on a Mac and viewed in
Acrobat. I would expect, with sprites for example, for all colour images to
appear in monochrome, but in a recent example with embedded colour (RGB)
JPEG images some appear to have been converted to monochrome, while some
remained in colour.

Can anyone tell me what happens to embedded colour JPEG images when
outputting what should be a monochrome PostScript file?
