I thought you might.
I've just run printcal on a CMYKcm .ti3 file from gplin and my Epson
R285, and noticed that the DELMAX_AIM values for c and m are somewhat
lower than I expected. Would this be due to the reduced L range for
these inks?
Hmm. As far as I can tell the auto aim values are for 100% colorant
for your file (ie. if you do a plot with -p, all the crosses are at 1.0),
since your device response is already pretty linear, and doesn't fall
over very much near 100%.
[If you look at the .cal then DEVMAX_USED is 1.0 for all the inks.]
Of course the two light inks are capable of less DE than the full inks,.
and this is reflected in the DELMAX_AIM values.
cheers,
Graeme Gill.
