With the proof standards Fogra49 and Fogra50 for the first time a proof standard was created that is not binding for printing. Why?
Fogra49 and Fogra50 describe two colour spaces as they are created by foil lamination not after printing but after printing and finishing.
- Fogra 49 refers to the ICC profile: PSO Coated v2 300% Matte laminate (ECI) – PSO_Coated_v2_300_Matte_laminate_eci.icc
- Fogra 50 refers to the ICC profile: PSO Coated v2 300% Glossy laminate (ECI) – PSO_Coated_v2_300_Glossy_laminate_eci.icc
Why were these profiles created?
Print finishing plays an increasingly important role in the further processing of printed matter. The application of a printing varnish, for example, is nowadays usually done directly during the printing process, e.g. with dispersion varnish in a 5th inking unit. The print image is usually only slightly changed in the process: An dispersion varnish, for example, results in a dot gain of 2-3 percent, a UV varnish up to around 5-7 percent. In contrast, foil lamination with OPP foil has a much stronger
influence on the colourfulness of the printed piece: the dot gain here is over 10 percent, the colour changes at values from Delta-E 5 to sometimes over Delta-E 10. And while the colour change of a dispersion varnishing can usually be checked directly at the press and in case of doubt also corrected, the foil lamination takes place at a later stage and usually not at the printing plant but at a finishing company. The colour change is therefore neither immediately visible to the printer nor can it be compensated for.
- Gloss foil lamination: richer colours and darker depths
- Matte foil lamination: paler colours and brighter depths
- Colour changes: Tone value increase >10% already in light areas, colour shifts average Delta-E 5 to over Delta-E 10
This is where Fogra 49 and Fogra 50 come in: a proof in Fogra 49 can precisely simulate the effect of a matte foil lamination and the associated colour change. Fora 49 is based on a print according to ISOCoated V2 300%, i.e. Fogra 39, which is then subsequently refined with a matte foil lamination.
Using the Fogra 49 and 50 profiles, the effect of foil lamination can be made visible – not only in Photoshop.
The print data can also be set directly into the profiles. The proofs, which then appear lighter, are correct because they become darker and stronger after the foil lamination due to the dot gain. The UGRA/Fogra media wedge is also measured correctly at Fora 49 and 50. However, it is important to note that the “finishing proofs” must not be used for matching in printing, as they simulate the finished result but not the previous print. Therefore, you should actually proof twice. Once in ISOCoatedV2 as a vote for the printer and once in Fora 49 or 50 to simulate the effect of foil lamination for the layout designer and the customer.
The ECI therefore also emphasizes the unambiguous identification of the proofs and recommends an imprint on the two proof variants:
- For the Fogra 49/50 proof: “Finishing proof! Must not be used for print adjustment.”
- For the Fogra 39 Proof: “Standard Proof for adjustment! Print will later be refined and fuller.”
Different effects of foil lamination:
Left: Original image ISOCoatedV2 300%
Centre: Original image ISOCoatedV2 300% Glossy Laminated
The image becomes much darker, especially in the area of green meadows and the sky
Right: Original image ISOCoatedV2 300% Matte Laminated
The image becomes darker in the mid-tones, but the black areas become lighter due to the matte foil lamination
Glossy foil lamination with prior correction by profile conversion according to PSO_Coated_v2_300_Glossy_laminate_eci.icc
Left: Original image ISOCoatedV2_300%
Center: Offsetprint after conversion to PSO_Coated_v2_300_Glossy_laminate_eci.icc
The print looks much too bright, especially in the area of the meadows
Right: Offsetprint after conversion to PSO_Coated_v2_300_Glossy_laminate_eci.icc and subsequent glossy foil lamination
Due to the dot gain during lamination, the print looks very similar to the original document in ISOCoatedV2_300%
Matte foil lamination with previous correction by profile conversion according to PSO_Coated_v2_300_Matte_laminate_eci.icc
Left: Original image ISOCoatedV2_300%
Center: Offsetprint after conversion to PSO_Coated_v2_300_Matte_laminate_eci.icc
The print looks much too bright, especially in the area of the meadows
Right: Offsetprint after conversion to PSO_Coated_v2_300_Matte_laminate_eci.icc and subsequent matte foil lamination
Due to the dot gain during lamination, the print looks similar to the original in ISOCoatedV2_300%. Only the black areas are clearly brightened by the matte film lamination.

This year we once again created proofs for Fogra certification and sent them to Munich-Aschheim for testing. With these proof prints, which we print according to three different proof standards and on three different papers, we point out that we not only deliver excellent proof quality through internal quality controls and checks, but that the quality of our proofs is also measured and confirmed by external experts. We have now had test prints certified by Fogra for the 12th time. We have also been “Spot-cert” certified for the display of … read more
At long last, we are able to fulfil a request made by many of our customers: from now on, you can register two email addresses in the Proof Shop – one for logging in and receiving status or tracking emails, and a separate one solely for receiving digital PDF invoices. Over the past few years, we have already switched many Proof customers to digital invoicing at their request, i.e. we generated a PDF invoice and then sent it manually to a second email address on file with us in the … read more
Whether it’s a large global corporation or a small company, the following often applies to designs or redesigns today: we develop everything for digital first.
Having missed last year’s annual conference in Dresden at the last minute due to illness, I am all the more delighted to be attending this year’s event in Darmstadt. The programme is once again very exciting and varied! I’m particularly looking forward to Dr Andreas Kraushaar’s workshop ‘Measuring in Images’, the HDR lecture by Prof. Dipl.-Ing. Florian Süßl, and the insights into ‘Perzabsolut’ from Dr Moritz Feil. As we discovered at the last Colour Management Symposium in Munich, Moritz Feil – whilst working at the Technical University of Munich – … read more
The most important colour management event takes place every two years in Munich: the Fogra Colour Management Symposium. Once again this year, all professionals are invited to make the pilgrimage to Munich: two days of lectures, discussions and a Bavarian evening await participants. Matthias Betz, owner of proof.de, will also be there again: for many years, he has been taking advantage of the opportunity to exchange ideas with colleagues and friends, learn about new technologies, hardware and software, and talk to colleagues from Fogra, freieFarbe, GMG and many more. In … read more
In recent weeks, there have been lengthy discussions on the Fogra digital printing mailing list as to whether a research project should be launched to define standardised tonal value gradations for spot colours. What is this all about? In the field of CMYK and seven-colour printing, the definition of clear, printable and proofable standards is well established and has been tried and tested in practice. If the paper or paper class is known and defined, a measuring standard such as M0/M1/M2 has been established and the content of optical brighteners … read more
Over the last few months, we at Proof.de have been thinking about further improving our already very good colour measurement technology in terms of speed and measurement precision. Relatively quickly it became clear that only two devices would come into question: The KonicaMinolta MYIRO-9, the successor of the former FD-9, or the X-Rite ISIS 2 XL. The starting point: Since we at Proof GmbH have 5 proofing devices, the calibration of targets for profile optimisation is a time-critical undertaking for us. Therefore, we had been looking around for an upgrade of … read more
In recent years, various problems have arisen with our previous proof paper supplier. On the one hand, we sometimes had to wait more than three months for paper deliveries; on the other hand, we sometimes had significant problems with batch-to-batch discrepancies, surface defects and much more. After lengthy deliberations, we decided in December to replace all the paper. We therefore received pallets of new paper at the turn of the year, which we are now gradually incorporating into our production. There will be no hard cut, but the new papers … read more
Even almost 9 years after the introduction of the successor colour space PSOCoatedV3, ISOCoatedV2 / FOGRA39 is still the most widespread colour space in Europe. We at Proof GmbH count around 200 jobs from time to time for the German Printing and Media Industries Federation, among others. In the last count, proofs in ISOCoatedV2 accounted for around 68% of all proof jobs at our company. This is a clear sign of the continued widespread use of the colour space. ISOCoatedV2: From the classic colour space to the beacon of the … read more
