Actually, ther is no restriction in what you can do with a profile
doctored by DoctorPro.. The only restriction is that which would
already exist regarding the null profile or whatever profile you altered.
For example.. If the original source profile was made with a standard
license version of Profile Plus or Profiler Pro, you couldn't distribute
the doctored profile.. If the source profile was public domain or
licensed for distribution, you could distribute the doctored version freely.
Here it is from "the horse's mouth."
"I'm a little short on info here... but if you are speaking of applying
Photoshop curves of your choice to an RGB or CMYK profile, then yes,
DoctorPRO will do that nicely. You do need to have a starting point, so
a "null" profile would be needed if you did not have a profile that
described the current state of your device, and "null" profiles are not
trivial to create; nor as simple as they sound. If you are speaking of
B&W workflow, where the channels are not RGB or CMYK but "your choice of
random grays" instead... then building a Color Look Up Table from
channel curves, and applying it to the inks in your system would be an
unlikely idea... since it would incorporate certain assumptions about
the relationship of the channels to one another in building the color
cube, and those assumptions would not be appropriate to non-colored
inks. "Keeping the entire workflow in grayscale" pretty much invalidates
the color cube in an ICC profile, as it would only use values from the
axis of that cube, in other words it would allocate the distances
between the points on the black-to-white rod through the middle of the
globe, not any other points in or on the globe, as it would with actual
color data... and would only locate a modest number of points on this
line, for that matter.
As for the licensing agreement: DoctorPRO edits profiles, it does not
build them, and as such, no limitations are put on the use of the
resulting profiles, other than those restrictions already on place from
the profile you started with.
