Marco,

I just switched over to a Canon i960 (my faithful e890 mysteriously passed
away on Xmas eve?). In the Color Options screen, there are three choices:
ColorSync, Canon Standard and None. I am on Panther 10.3.1. I can tell you
that, when I select None among these three choices indeed *nothing* happens,
colorwise, that I can see, touch or otherwise observe directly, nothing past
the basic internal driver conversion from RGB to CcMmYk -- nothing. Nothing
in ColorSync and nothing anywhere else. FWIW I leave ColorSync Conversion to
'Standard' and Quartz Filter to 'None', their defaults settings. I suspect
these latest Panther-enabled ColorSync settings are doing nothing to the
data right now, color is handed on down to the driver unadulterated. Proof
is when I profile the printer (which btw is very, very nice) in RGB with
TC9.18, measure and make a profile out of that I later use to make
conversions with, in Photoshop, well, the color results I am getting are on
par with my usual (OS9, OSX Jaguar+) expectations: colors are sharp, vivid
and faithful to my original image. In fact, I am getting better shadows
details with the Canon RGB driver than with the Epson RGB driver! But that's
another story...
