Thanks Simon. Some valid points there but I've already ruled out your
suggestions.
After re-profiling (creating a version 2 ICC profile) and again
discovering that my custom profile returned the same result as the
Epson canned profile, I read this document from x-rite) :
http://www.xrite.com/product_overview.aspx?
ID=1161&Action=support&SupportID=5187
Note that the document instructs to use Epson Color Controls when
printing your test charts. I did not do this when profiling and
instead chose ColorSync. Does ColorSync in SL associate itself with a
default profile? Since my profile returned the same result as the
Epson "canned" profile, I'm going to assume that Epson's profiles are
pre-Snow Leopard and were created in the same way. I will re-profile
once again hoping this will correct the problem, since I can find no
other advice or solution (if there is one).
Note when you print with Photoshop color management, the setting is
ColorSync (a pre-selected grayed out default, I believe)
Sorry for the elementary query, but since there was an apparent lack
of interest in my OP, I challenge the list for a solid explanation -
game on anyone?

Hi Joe,
In answer to your direct question: No.
However, the following seem possible (apologies if these are
obvious and already eliminated):
1 Epson rumoured to have modified drivers (Epson 2880 reported)
with result that (non-Epson) continuous ink systems do not work
properly in recent release. Epson inks/cartridges not affected.
Seems likely that there would be zero difference between CS3 and
CS4 in that case as everything would be driver dependant.
2 Is it possible that you have printed with "absolute colorimetric"
intent? (The presence of optical brighteners in most papers
requires the system to supply a lot of yellow ink to compensate for
the underlying blue-ish paper 'white').
3 It is possible that the image content (if using "perceptual"
intent) could under some circumstances affect colours in an
unpredictable way, because the perceptual remapping (to constrain
everything to printer gamut) can potentially affect many other
colours. This is a purely speculative suggestion, and the
possibility could be eliminated by checking with a very desaturated
image (e.g. a greyscale).
4 The obvious issue of blocked (cyan/light cyan) ink delivery
(...nozzle check?)
I would be cautious about reprofiling, because it feels like
applying a band-aid to stop the bleeding instead of taking the
razor-blade away! However, if it works..........then it shows that
it pays to be pragmatic.

I'm experiencing some strange color behavior when printing from
PhotoShop CS3 running Mac OS 10.6.3 to an Epson SPR1900 using
Epson Ultra Premium Presentation Matte paper with the latest Epson
driver. There is a strong yellow cast happening. All CM and print
settings are correct. The result is the same when using the Epson
paper profile or my own custom profile. Didn't notice this problem
previously with older versions of the OS. I'm about to re-profile,
but I'm wondering if the problem lies with OS X and/or the Epson
driver. I'm aware of issues with Snow Leopard/CS4/Epson drivers,
but has anyone been down this particular road or close to it?
Thanks,
