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.

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 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
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
Digimarc is a digital watermark that can be used to embed information in images, videos or other media. Digimarc watermarks are invisible to the human eye, but remain recognisable to special software or devices. Digimarc is becoming increasingly popular in the packaging sector in particular, as this technology allows the digits of the EAN barcode and more to be applied invisibly to all areas of the packaging. Digimarc and EAN barcode at the supermarket checkout When scanning at the checkout, the checkout staff do not have to search for the … read more
A new generation of colour measuring devices is entering the market: in contrast to the classic measuring devices, which are available as a fully encapsulated system either as a colourimeter or as a spectrophotometer, and then supply the data to a computer via an interface or app or display it directly, the new generation of colour measuring devices consist only of lighting and software, with the optics of a modern iPhone from Apple being used as the sensor. Until now, there have been two categories of measuring devices on the … read more

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
Today I received an email in which PANTONE asked how it should orientate its products and services in the future. The users were asked which countries, industries and company sizes they come from, but also what PANTONE products should look like in the future and what customers would be prepared to pay for PANTONE services in the future. Question: How much can PANTONE services cost? PANTONE appears to be orientating itself on the PANTONE Connect prices: All price queries have the lowest price category < $ 7,- / month, i.e. … read more
After Eddy Hagen pointed out in this posts, that there were some major colour deviations between the brand new PANTONE Solid Coated Guide 2023 and the previous version especially for the PANTONE 2635 C, I was curious to lookup the same colours in the new PANTONE Color Bridge Coated Guide of 2023 and compare the colours with the previous version. I measured a dE00 of 8,15 between the two colours that Eddy mentioned, which is really far apart from how accurate PANTONE colours should match between the different PANTONE guides. … read more
Adobe products are ideal for image retouching and layout and handle RGB and CMYK colour profiles very well. However, when editing and retouching grayscale images, for example for a black-and-white photo book, the experience is quite different. Suddenly, images look completely different in InDesign than they do in Photoshop, and even when exporting the image to PDF, greyscale images are suddenly treated differently. This article explains where the problems lie with black-and-white images and greyscale profiles in InDesign and Photoshop layouts, and how you can work in a more ‘colour-accurate’ … read more
