Hello Henk
Thank you very much.
I didn't know the story for Euroscale/Fogra.
It's amazing that some printers don't know that either.
Some of the ink producers still recommend Euroscale inks although Euroscale
is no standard anymore.
Euroscale does not exist!! No more!!
Since a few years ISO 2846-1 is the standard for inks for offset and color
separations based on these inks can be made with the Fogra profiles as
supplied by ECI and Adobe.
In Photoshop and CS it's the default for European Prepress applications.
Adobe calls it European but that's only because the North Americans still
don't use ISO standards for that purpose.
ISO standards are used in far more countries than the 25 European countries.
So, in every discussion with printers and.or intermediate media vendors you
can use the ISO standards for both inks (ISO 2846-1) and print (ISO
12647-2:2004).
Some of them 9still) don't use them because "the Market" does not request
the usage of these standards. They say.
Your newspaper printers recently agreed to use one standard called ISO
12647-3:2005. The inks are based on ISO 2846-2.
In a country like Holland all newspaper printers and coldset web offset
printers (weeklies and cheap freesheets on uncoated paper) use these
standards since January 1 2005.
All photographers know in advance how their digital material will behave on
that paper. ColorSync provides the ability to simulate the CMYK output on
your screen.
IFRA (www.ifra.org) is the international association. They were able to
convince all their members that advertisers and suppliers of digital files
(such as photographers) want to optimize the process and want to get
identical results.
They investigated and researched market needs and agreed to use just one
printing condition for North America called standard 30 and one for the
rest of the world called 26.
These profiles are labeled ISOnewspaper30 and ISOnewspaper26. and can be
downloaded free of charge.
regards, Henk
