Thank you very much for replying to my query. However, your reply 
puzzles me: my ignorance perhaps.

The method you describe for printing test sheets is the one I am 
accustomed to use. I have reprinted the sheets but see no difference 
between the latest and those I printed earlier. I shall measure them 
when cured.

I have always understood, that, apart from selecting the profile in the 
photo software, you print with the same settings as those used to print 
the target, so with the older dialogue you select "Off (No Color 
Adjustment)" rather than "Color Controls" or "Colorsync". With the newer 
dialogues, to achieve the same result, I select "Epson Color Controls" 
in the Color Matching tab, and "Off (No Color Adjustment)" in the Print 
Settings tab (just as you describe for printing the target sheets). This 
gave me the desired results with OS-X 10.5.x; but with 10.6.x, the OS 
seems to override my choice in the Color Matching tab, in a somewhat 
erratic fashion. When I CAN select "Epson Color Controls" in the Color 
Matching tab (and, of course, "Off (No Color Adjustment)" under Print 
settings, the prints come out fine.

I have always understood that the Colorsync setting allows the driver to 
select the profile linked to the media choice when you allow the printer 
to control color management; but I am open to correction.
