Dear Matthias,

You are right, the Fogra51 paper is blueish, because it has very much OBA. But if you compare an F51 proof with an F39 proof under D50 lightening you will find the F39 colors are reddish and F51 will be much closer to the result  on the printed material. And the F39 paper simulation is not usable for F51 papers, because the paper color is yellowish. The press operators like F51 proofs for Type 1 papers.

I do not understand the problem. F51 proof for OBA papers, and F39 for non OBA papers. And always will be a little difference between F39 and F51 proofs. But not big difference.  It is normal. (Of course, the files were made with the right color profile for the proofs.)

Hello,
I had the same problem when implementing F51 (EPSON printer w M1 Spectroproofer and CGS ORIS RIP). It was the paper white simulation from the profile/measurement data that added red to both objects and images. It wasn?t always easy to see but sometimes completely disturbing in highlights.

The resolution to this was to remove the paper white simulation from the calibration completely and also switch to another F51 approved paper brand.

If anything the F51 should look ?cooler? than F39.

Thanks for your reply.

We have been extensively testing different environments/viewers, ways of converting images/profiles etc.
No matter what we do they always seem warmer/more red compared to what
we?re used to with 39L

Have you heard of this problem from anyone/anywhere else?

Many thanks
Simon

Are you comparing:
a) images converted to Fogra39 and proofed on Fogra39 approved proofing media
to
b) images converted to Fogra51 and Fogra52 proofed on Fogra51 and Fogra52 approved media?
Out of curiosity, please try compare your proofs under direct sunlight...

No we?re proofing on Fogra 51 and 52 approved paper.

Subject: [ECI-EN] Fogra51 and 52 looks warmer compared to 39L
I wonder if you can help me.
We have recently upgraded our Epson proofers and EFI RIP in order to have the facility to produce Fogra certified proofs to 51L  and 52L specifications.
Having spent quite a long while creating media profiles for both of these plus 39L, it seems that all Fogra 51 and 52 proofs appear ?warmer? than 39L results.
We have been using 39L for many years now and have superb results. Part of our work is fine art photography reproduction, so accurate colour is essential.
When proofing on our Fogra approved 39L stock, the results are as we would expect. Not so with 51 and 52.
We have a viewing booth fitted with the latest generation VeriVide tubes conforming to ISO 3664:2009 conditions.
All proofs we produce pass Fogra certification with very low deltaE values, but 51 and 52 proofs always differ from 39L.
I have had proofs made by a qualified third party and their results mirror ours.
Could you give me any advice as to whether this problem can be resolved?
Yours Faithfully,
John Bodkin
