[Gimp-print-devel] Stylus Photo stuff

[Robert L K. <rl...@al...>]

I recalibrated the transfer function for the Photo EX (and the Photo
700 and Photo, and hopefully for the 1200 and 750 as well).  This
should improve saturation and gray fidelity.  You'll definitely want
higher brightness settings; things will appear quite a bit darker
now.  Things will also probably appear less yellow.

For the people who care about the details, I changed the conversion
factor between dark and light ink from 2:1 to 4:1 for both cyan and
magenta.  The effect is that one dark dot is equal to four light dots
in the calculations, and in general more cyan and magenta are printed.

The old transfer function gave a noticeably sharp transition region
between the two inks.  The new one is much better.
