As a driver developer the recent threads on selection of colour paths through
non-Postscript drivers for profiling has been interesting.
Obviously your requirements for such a path include:
1. The colour behaviour must be repeatable.
2. Colour gamut should be maximised.
What else would you add? I can see that a linear response and an appropriate ink
limit when printing the testchart would be candidates if your characterisation
tool does not have pre-profile linearisation and testchart ink limit controls.
Would you prefer the driver perform those functions even if they are in the
characterisation tool? If so, why?
The driver obviously has to do the RGB to CMYK conversion for you due to that
pesky operating system limitation. Would you prefer it do a simple conversion
which makes no assumption about the nature of the ink and substrate, such as the
"classic" one-minus RGB to CMY conversion with K=min(C,M,Y), or would you prefer
a "fixed" accurate colour conversion, from say Adobe 98 to a canned output
profile?
