Marc,
My "dream" of profile editing software includes (among other things) the
following:
1) Editing of both sides (AtoB and BtoA) of the profile in a single
operation. You define if your editing "moves" are to be applied in the
AtoB or the BtoA side, and then it reverses them and applies to the other
side too.
2) Editing of all tables (relative and perceptual) and both sides (AtoB
and BtoA) at once.
3) Gradation (per channel) editing of the neutral axis, pulling along
low-saturation colors in a smooth way. Similar to PrintOpen 4's (PC)
editing capability.
4) Global Gradation (per channel) color editing that leaves the neutral
axis untouched. In other words, the inverse of (3), editing the saturated
colors without affecting neutrals and barely affecting low-sat colors.
I suspect that (3) and (4) can indeed be done in ColorBlind Edit, but
maybe it requires a lot of effort?
And what about (1) and (2)?
Maybe (1) needs a little more explaining.
You have the output you got from the profile, and your file, and a
calibrated monitor.
You can edit in two ways:
a) making corrections that will correct the output (if the print is more
cyan than it should be, you reduce cyan); this is the typical profile
editing program. Corrections are meant to be applied in PCS-Device table.
b) making corrections for the screen to match the output (in above case,
you add cyan to make the screen match the output). Here corrections are
meant to be applied in Device-PCS table.
In either case, you should be able to rebuild the other side of the
table, or otherwise apply the inverse correction. So that the profile
mantains consistency.
