Hi, we are testing out an Epson 9800 right now and were having some
issues.
The red (100%y 100%m) Doesnt get red enough. To low intensity. And
the Delta E value landing on 9! All other colors are good. Im been
searching the net but havent found anything about this.
Im using GMG Colorproof and Fogra39 values.
Any ideas whats wrong?
This might be th wrong forum to ask about this but I'll give it a go
anyway.

Hi
>From tests I have carried out I would agree with ECI's recommendation that
the 300 TAC profile is best for web and the 330 TAC profile is best for
sheet fed.
However there are some conditions where the 300 TAC version is best for
sheet fed presses, i.e. long perfectors etc, and in some cases, with good
web presses and papers, using the 330 TAC profile will give a great result.

I'm a little confused about the use of the new profiles "ISO coated v2 (ECI)" and "ISO coated v2 300% (ECI)".
ECI states on there website:
"For two standard offset printing conditions new profiles are available. ECI, bvdm and FOGRA jointly recommend the use of "ISO Coated v2 (ECI)" and "ISO Coated v2 300% (ECI)". The latter is a version with lower maximum ink coverage (300%) suitable for e.g. heat set web offset."
As I interpret your text, the profile "ISO Coated v2 (ECI)" is for Sheet-fed offset and the profile "ISO Coated v2 300% (ECI)" is suitable for heat-set web offset.
Now. on Ugra's website I have found this text:
"The new profile ISOcoated_V2_300.icc is used for the separation of data. If there should occur problems with insufficient blacks, the profile ISOcoated_V2.icc with a total area coverage of 330% should be used. swiss4color recommends however, to use the profile with the total area coverage of 300%.".
Should I use "ISO Coated v2 (ECI)" for Sheet-fed offset and "ISO Coated v2 300% (ECI)" for heat-set web offset? Or is it like Ugra wrote on there website, always "ISO Coated v2 300% (ECI)" for Sheet-fed offset, and only if I should experience problems with insufficient black, then to use the profile "ISOcoated V2 (ECI)".
Yours sincerely

Dear members of the [ECI]-Mailing list,
today ECI publishes a new version of the ECI RGB working space named
eciRGB_v2 which is technically identical to the LStar-RGB profile
from Color Solutions which has been around for a while.
The main difference - compared to the original eciRGB 1.0 profile
published back in 1998 - is the use of a luminance axis which is
linear in L* instead of a gamma of 1.8. In addition, the profile is
available both as an ICC version 2 profile as well as an ICC version
4 profile.
From a practical point of view the changes are only minor but ECI
currently works on incorporating eciRGB_v2 into an international
standard as part of the ISO 22028 series. In order to achieve this
move towards standardization the older profile had to be revised and
among other things the viewing conditions had to be clarified. The
document with the detailed specs that fulfill the ISO 22028-1
requirements will be published in the near future.
What to do with your current images and files?
It is not recommend to change existing images or other files –
neither convert them from eciRGB 1.0 to eciRGB_v2, nor simply assign
the new profile to existing images or files. For any new images or
data it is recommended though to move towards using eciRGB_v2 as the
working color space for RGB data.
For a more detailed explanation of the new eciRGBv2 profile and its
advantages please check out http://www.eci.org/eci/en/
