You’d use what instead? What empirical data can you provide to the
list that Photoshop or any other Adobe app has issues converting
color spaces?
Odd that nobody but me has thought about factoring in Photoshop as
the culprit for a good proportion of the banding and clipping that
you'll see in the printed result :)
Its not at all odd until you explain yourself more clearly.
I took a test target that is supposed to highlight problems with ICC
profiles and printer linearity/gamut.
I printed it from Photoshop and it was far more bandy than I'd have
expected from the profile that I'd built.
So I used Graeme's ArgyllCMS to convert a copy of the test image to
the same printer profile and then sent this from Photoshop to the
printer.
The results are significantly different.
The PS conversion is bandy and ugly looking. The Argyll version is
extremely smooth and sexy looking.
Draw your own conclusions...
