Ok, Robert, I'll make a constructive suggestion. As we all know,
Epson 2400 printers are VERY popular with the photo community, made
to fairly close tolerances, and used by people who are knowledgable
about profiles.
I also happen to have one. Now, show me how I can send Joe User a
settings file for a paper eg. Epson Heavyweight Matte that will
allow profiled printing, so that I can send him (or post on a Wiki)
a usable profile. A quick hack to spool in settings would allow
non-techie users to use configurations provided by the more
knowledgable crowd.
And please don't tell me it cannot be done because the information
is kept in data structures - if it can be set interactively it can
also be set by a script. Let's try to do for this one printer type
and see how nasty it is. Then we can do it for the whole Epson
pigment family in RGB and that will be really useful to a bunch of
people. The desire for color management is at the moment actually
confined to a small number of printer families.
I've already given you one answer: use the PPD files for that
purpose. Take a PPD file, set its defaults to what you want, and then
distribute that.
My recollection is that you didn't like this answer, although I don't
remember why. My other answer would be to use the GIMP and pass
around printrc settings (which can also contain curves; PPD files
can't contain curves). Beyond that, I don't have any obvious ideas.
I suppose you can pass around perl scripts or whatnot that set the
necessary settings in PPD files if you want.
The proposal to prototype this for one printer model is misplaced.
The nature of the Gutenprint driver is that any solution that will
work for one printer will work for any supported printer, so once we
have a solution for the 2400 we'll also have a solution -- the
identical solution -- for the C40. The hard part is coming up with a
solution in the first place -- once we have one it will work for at
least all other Epson printers, and perhaps for all supported
printers. Whether it will scale is a different issue, but pretty much
any simple solution based on the current platform will scale.
