My "wish list" would be a little program which could read printed results
for a particular printer.  See below...

Roy did the existing profiles as generics - they are not constructed from
actual data and assume a linear greyscale.  My wish would be for a little
program that, say, read a text file of actual data.  First variable would be
for the number of observations making up the greyscale readings...21, 51,
...256.  Then a list of observations printed by the a particular printer
with a particular workflow (Epson Adv B&W, QTR, BO....) as measured say with
Quickread (or similar) in order to construct the kTRC tag.  The list would
also pick up the media white point wptp tag.  Then you have an ICC profile
for your printer, your workflow and your ink etc.  Conceptually it is not
difficult.  Roy or the like can tell us how difficult it would be to
program....and to find the time to do it..  :-)
