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.

Dear list members,
If I remember correctly I once did read on the ECI or PAB list that one
could exactly measure the content of a specific color gamut.
I don't know for sure but one used the Characterization Data (such as Fogra
39) or the profiles
(such as ISOcoated_v2).
For an article on the amount of colors that can be reproduced I would like
to compare:
Fogra39
Fogra29 and
Fogra30
or:
ISOcoated_v2
ISOuncoated and
ISOcoatedYellowish
Do you know (or remember) who could provide these figures.
I would like to use them in my next article.
Thanks for your help in advance.
Regards,
Henk Gianotten

Hello Henk
If you mean gamut volume in DeltaE^3, Heidelberg PrintOpen gives that figure
both for profiles and char data
Fogra39 367 433 DE^3
Fogra29 173 308 DE^3
Fogra30 157 066 DE^3

Dear Henk,
Apologies for the late reply, but thank you very much for your explanation
regarding Adobe profiles vs ECI profiles.
Much appreciated.

Hi Michael,
Thanks for your answer, this is very useful. I am trying to take some
densitometric values, although ISO 12647 is using the CIELAB colorspace I am
using densities as a starting point for the dry and wet densities ( to
account for the dryback).
Can you please precise what kind of differences we can expect from one
standard to another.
Thanks, Steeve.

Hi Nick,
I am not one of the selection of ECI experts but it seems that they all are
in Stuttgart for their important Media Producers Forum.
I am just one of the Dutch ECI list members.
I will try to answer your question and most probably you will
get more details of the 'real experts' after the weekend! :-)
The most important information for the speccing of printed material
is the "Output Condition". In some applications the system refers to
the "Output Condition Identifier". It links to the data needed to describe
the actual color gamut for a specific combination of process, paper and ink.
The Characterization Data is identical to the Output Condition.
The Characterization Data is based on a specific set of dot percentages
and dot gain or Tonal Value Increase for CMY and (most probably)
a higher one for K. There is no GCR and UCR in these prints.
The next level is the Output Intent or profile for that process-paper-ink
combination.
The GCR is part of this profile and important for the printing process.
Fogra created the Characterization Data such as Fogra 39.
ECI made a set of profiles such as ISOcoated_v2. They even made another
profile based on the same Fogra39 characterization data but with a lower
CMYK TAC. That profile is labeled ISOcoated_v2_300. That has just 300%.
The ECI profiles have a relatively high amount of GCR.
Adobe made also profiles based on the same Characterization Data fogra39
however with a different GCR setting. As you most probably know GCR
can have a length component (amount of UCR and length of K) and a width
component. That describes the amount of tertiair colors (CMY combinations
replaced by K. If all those "dirty" colors are replaced by K we have
maximum GCR. Until recently 50% GCR was the maximum.
The Media Standard Prints 2007 (www.bvdm.org) now describes a maximum
GCR setting of 70%.
Adobe and ECI build profiles based on identical Characterization Data but
Adobe has (in general) a lower GCR.
Some Americans prefer that. Some Europeans too.
Recent tests show that we easily can reduce the amount of GCR if
we have a good process control.
I would suggest to talk to you printer. Perhaps they already tested both
profiles side by side and know what they have to advise.
My personal experience is that we have good reasons to increase GCR.
It's good for the stability of the process and will improve the quality
(major reason). Of course one has less visual register problems, less ink
consumption and less drying problems. Printers like it.
Major conclusion: Recent Characterization Data is very important.
So Fogra39 is better than Fogra27.
Both ECI and Adobe made profiles based on the most actual CD (Fogra39)
Quality of the profiles and amounts of gray balance and GCR are the next
point to check.
I hope this info helps
