New subject: ECI-RGB / Any advantages?

15 Dec 2003

      Hello

The print densities were quite high (C 2.1, M1.9 and Y 1.65, with polarizing
filter) and this test was more for scientific purposes so the point Chris is
making is probably very true. But if for spesific job printer would like to
use high densities to achieve larger gamut wouldn't ECI-RGB make sense in
that case?

 Hello Jouni,

 Interesting.
 I guess when you would print at standard densities both RGB 
 colourspaces would be large enough?
 Are the targets that you printed with these "higher than 
 normal" densities still within the ISO standard?

 Hello!

Here is an example connected to this discussion. I have   compared ECI-RGB and
 Adobe RGB with CMYK output profile (this has been
made on   sheet-fed press
 using quite high print densities to get wide
gamut).

I have taken out two examples on different L-levels. On L 43   CMYK profile
 exceeds clearly Adobe RGB on magenta shades
(almost ECI   also) and especially
 on higher L-level CMYK exceeds Adobe RGB on yellow
areas but   is still inside
 Eci-RGB.

I don't know if this is correct way of looking - please   correct me if I am
 wrong. However it looks like when using special
printing   condition meaning
 high print densities ECI-RGB seems to be better
choice than Adobe.
