I thought you were nuts at first CDT but I think I understand the thinking
now a bit better:
* Determine ink limits, both per channel and total, PRIOR to printing the
target (Best does this using linearization and total ink settings, as do
other CMYK RIPs).
* Separate RGB target to these CMYK parameters.
* Print, measure and profile.
The hole I still have in my thinking is:
* Is building the ink limit/linearization data into the CMYK target
*inherently* better than printing a "raw" target and having the RIP apply
this supposedly same data to the target during printing. Does one somehow
preserve more of the gray levels or produce smoother profiles than the
other? Why?
* Doesn't the profiling app need to know what CMYK values were in the target
(reference data in ProfileMaker terms) and where does it get this? In other
words, is there a magic application that can simply "read" the CMYK values
in the target and translate it into a properly formatted text file for the
profiling app to reference to when measuring the print and generating the
profile? Or does one have to go thru patch-by-patch and manually create the
text/reference data?
