Using Argyll I would for example generate a large number of color patches
that I would print on 1 or more sheet of a transparent media like Pictorico.
Read the colors back (spectrophotometer) to do the profile for this printer
its inks and this transparent media as usual. That's phase one sort of
Phase two, is to use these same colored transparencies as a negative to
print on some photographic paper. Each patches would be read back but this
time from the B&W photographic print, a practically black and white image
Now I have a large number of color patches printed on a transparent film
that when used as a negative will give us some greyscale values or almost on
the photographic print.
Is there somekind of profile that I could create either manually or
otherwise to convert the greyscale values in my original B&W digital image
to colors that would result in the equivalent tonal values on the

I would like to create a somekind
of profile that convert a monochrome image, say only L* is useful to
another set of LAB values where now these are colors. The purpose of
such a conversion is to produce a "colored" negative to be used in a
