conversion is bandy and ugly looking. The Argyll version is extremely
smooth and sexy looking.) using the same profiles?
As I mentioned before, I think it's much more likely to be related to
creating specific profiles using Argyll than the particular CMM used
to apply the result.
[ There are some subtleties in applying the profile though,
that conceivably can cause banding issues. If the CMM "bakes"
a profile link sequence into an overall transform then there
are some interesting gotchas to do with how per device input
curves for XYZ PCS profiles are handled - but my impression
was that Photoshop doesn't convert to an overall transform,
and even if it does, that the developers would have noticed
this problem and solved it a long time ago.]
