[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.
