Kai-Uwe,

I am sorry I replied very hurriedly to your message. You are surprised that
at Gutenprint we are so eager to resort to profiles. Please let me explain
a bit more. The reason is that (hopefully) this will simplify the work of
supporting *new* printers and media, and in fact (hopefully) will allow us
to crowdsource such support.

Yes, we will bundle our own profiles in the same way as Epson or Canon now
provide profiles with every one of their proprietary photo printer drivers,
and in the same way as people who make RIPS for the graphics industry.
Color management is really useful :)

I think we will do exactly the same thing as the printer vendors do: For
each *new* printer we will make a few base profiles for "generic" matte and
glossy media that will allow Joe User to get a decent print; and for the
rest, well, ,we expect that users will make profiles themselves, order them
made if necessary, and exchange them on the internet, along with tuned ink
presets.

At the moment for each new printer settings need to be carefully tuned
manually for each paper type; thanks to profiling technology it should be
faster to support a new printer once we know how to get it to put ink on
paper.

printer type, thereby enabling the whole community to join together to
allow graphics users and in particular Linux users  to have access to the
newest printers.

I should stress that I own various spectros, and will make "canned" bundled
profiles for Gutenprint; As my instruments are very fast it takes me about
5 minutes to make a profile, so I do not expect a work overload. I will
make a quick profile for anyone who sends me an A4  printed target, maybe
requesting a nominal fee. Of course if someone wants a 5000 patch Atkinson
target read, I may really require a fee.

Profiles made with Graeme's excellent Argyll are of course entirely free of
copyright issues. And I will take the distribution issues up personally
with other profiling software vendors if and as they occur. Profiling tool
vendors are sympathetic to us because more profiles in use means more
instruments sold :) Indeed, Xrite have very kindly donated an instrument to
help Robert with linearisation.
