Dear List-members!
I'm trying to compare input with output profiles as well as output with
output profiles. These are all 4 channel CMYK profiles.
Case 1 - Input with Output profile:
Input profile: IsoCoated Euroscale ECI v2
Output profile: Ink-jet printer profile generated with Caldera (iPrism
v8)
Goal: the correct intersecting volume as calculated with viewgam -i
Question: What rendering intent is the correct one for such a comparison
(absolute RI?)? I want to know how much (in %) of the input profile is
printable with the output profile. And should I use iccgamut with "-fb" or
"-ff"? What and why is the correct setting.
Case 2 - Output with Output profile:
Output profile: Ink-jet printer profile generated with Caldera (iPrism
v8)
Output profile: Ink-jet printer profile generated with Caldera (iPrism
v8)
Goal: the correct intersecting volume as calculated with viewgam -i
Question: What rendering intent is the correct one for such a comparison
(absolute RI?)? I want to know how much (in %) of one profile is included
in the other. And should I use iccgamut with "-fb" or "-ff"? What and why
is the correct setting.
Please point me in the right direction.
Is there any paper, document, explanation about such undertakings?
Thanks in advance,
Georg Klima
