What you need too have in your minds always when you want to simulate
colours from one out put device to another? Always simulate worse output
device on better device. Under better or worse device I mean all process
including paper, so the process who give you better or worse results (colour
space). So in your case you must to simulate heat set web on sheed fed
press.

Hi Lars,
this is a frequent problem in our production too. Number 2 should be the
best way to go as Magnus stated. I should add that it's best to use some
heavy-duty solution for the DVL conversion like GMG Colorserver, as this
product not simply does a Colorimetric conversion, but tries to achieve the
same "look and feel" and visual apperance on the target medium. This is very
important, because the heat-set papers always more grayish than you use for
the sheet-fed presses, and GMG may correct for the lowered contrast and
smaller gamut.
Moreover, try to persuade the web printing house to embrace the new Fogra
45 and 46 standards. They're much more closer to the real thing and to Fogra
39 too.
Hope this helps, regards,
Peter Nagy

Hi Lars
My answer to question #1: Yes.
We produce several magazines with heatset web presses and according to ISO
12647-2, and we're using the well-known icc profile from the ECI: ISO Coated
v2 300% (Fogra39) on Galerie Fine paper.
I would like to add that I was said that M-real has categorised its Galerie
Range according to paper groups in ISO 12647-2, and they also have created
Galerie Fine specific ICC profile from the FOGRA39 data, optimised for
heatset printing according to ISO 12647-2. We have never tested that
profile, but I presume that working with that specific profile, you should
get best quality.
Kind regards,

Asunto: [ECI-EN] Heatset and Fogra39?
Hi listmembers,
I represent a sheetfed printing company. One of our customers is a heatset
web printing company and we print covers for their magazines.
We print very close to Fogra39, our proofs are mostly spot on and we
document and adjust our production with Bodoni pressSIGN software.
Our customer is happy, but often they have spread adds going from Cover
page 2 and over on the heatset web body page 3. The body is produced on a
Goss press on Galeri Fine Gloss and (they think at least) according to
Fogra28. As far as I know this paper is not like Fogra28 and Fogra28 is
replaced...anyway...I see three ways to get a close match between our
Fogra39 page and their heatset page if we say they can manage colors:
1. Is it possible to produce acording to Fogra39 on Galerie Fine Gloss on a
Goss press (ISO coated v2_300)?
This would be the easy way and give the best quality.
2. Color conversion from Customer press ICC profile to?Fogra39 with Device
Link profiles. We still produce according to Fogra39.
Colors on?cover page 2 and 3 are shrinked to heatset web on file level.
3. We simulate Customer press ICC by lowering gamut and gaining dotgain
with TVI curves.
?Hard way, lot of work for prepress, press and requires two proofs. Not a
good solution.
I?m hoping for answers that says that is possible to produce according to
Fogra39 in heatset web.
Thanks,
Lars.
