Proof GmbH Tübingen Fogra Certification FOGRA55 7C Matthias Betz examines 7C test form

We passed the first proof certification for the 7C proof under FOGRA55

A few days ago Proof GmbH was the first company to be certified for proofing for the new 7C exchange colour space FOGRA55. Fogra has developed characterisation data for extended multicolour printing with the printing colours CMYKOGV – i.e. cyan, magenta, yellow, black (contrast), orange, green and violet – FOGRA55 as part of a research project over the past few years. The characterisation data and the ICC profile Ref-ECG-CMYKOGV_FOGRA55_TAC300.icc have been published on the Fogra website in recent weeks. We have now carried out the certification via GMG ColorProof, as …

Title Test Report Fogra Certificate Proof GmbH 2021 Fogra Contract Proof Creation 34558

Proof GmbH 2021 Certified Again by Fogra with Fogra “Spot cert”

Fogra Certificate Proof GmbH 2021 Fogra Contract Proof Creation 34558

This year we have again submitted proofs for Fogra certification. We thus prove that we not only deliver excellent proof quality through internal quality controls and checks, but that the quality of our proofs is also confirmed by an external body. We have therefore had proof prints certified for the seventh year in a row.

Already in 2019, we were among the first to also be certified for the representation of spot colours (“Spot-cert”), and in 2020 we also went through Spot-cert in addition. And all in all, we have been successfully certified by Fogra for the ninth time in a row. Sometimes customers ask:

“You get Fogra certified every year. Won’t that become unnecessary at some point? You know you can do it …”

Yes, that is sometimes true. Every certification means effort and costs, the prints have to be made, sheets have to be filled in, everything has to be sent to Munich and invoices have to be transferred. And that’s just so that we can have the same high quality confirmed as in previous years. On the other hand, this isn’t true either.

Proofing is only superficially “service by the book as always”. In real life, no two years are the same. Proofing software, for example, is not sold on the mass market, so every update brings difficulties: Important functions fail, protocols are output incorrectly, optimisations do not optimise but worsen the results…: What we haven’t had to experience! Especially here it is important to have the security of certification by Fogra that even with the latest software revision all relevant processes still run cleanly.

The same applies to the hardware, which can be just as troublesome as the software: sometimes we have a generation change of proof printers, which always involves a change of inks and colour pigments, sometimes the driver or firmware is renewed, sometimes faulty print heads have been replaced …: Here, too, there are many possible sources of error that keep us on our toes. And here, too, the certifications bring us security for daily production – our everyday business. And that, too, is often not commonplace at proof.de:

Verifiably precise …

Our so-called “everyday business” is often characterised by special cases, exceptions and special requirements. Admittedly: We like to work off Fogra39 proofs in ISOCoatedV2, where all data is delivered in CMYK. Something like that just runs really smoothly for us. But apart from these “standards”, we process much more for our customers: we produce high-precision colour samples, proof individual proof profiles for metal decor printing, process thick, high-gloss papers for proofs and extremely thin, matt papers for art projects, apply PANTONE colours to roll-ups, fine art prints in AdobeRGB on cotton canvas, ECI-RGB-V2 on Hahnemühle papers, print XYZ colour targets for multispectral cameras and …:

Gamut map: The colour tool for cross-media design

Due to our involvement with freeColour e.V., at the last meeting in Switzerland the desire for a cross-media tool for designers was expressed with which one can create intersections of colourspaces from the freieFarbe CIELAB HLC Colour Atlas XL. With Gamutmap, Proof GmbH has now created such a tool, which is available to all designers free of charge. With Gamutmap nearly 100 individual colour spaces can be indicated from 34.250 colours of the entire CIELAB colour space, or intersections from many combined colour spaces can be indicated. An example: As …

proof.de Packaging of a Proof/ Digital proof

Proof cheap. What does that mean?

Proof cheap is a typical search term that people use in search engines to find a cheap, colour and legally binding proof. But what makes a cheap proof?

A proof is one that is produced according to the specifications of the latest revision of the proofing standard ISO 12467-7 and is within the tolerances of this standard. The current revision is ISO 12647-7:2016, which has been tightened even further with this standard and has been supplemented by a certified edition of spot colours such as PANTONE and HKS.

Such certified proofs can be ordered at shop.proof.de for all proof profiles.

But what makes the certified proof cheap? That’s the low price. Proofs are printed on certified proof papers on very high-quality pigment inkjet printers, usually using expensive proofing software, and measured with spectrophotometers. So how can production be done cheaply here?

1: Using cheap pigment ink?

One litre of ink for proofing devices is around 400 EUR, so it makes sense to use inexpensive alternative ink from China. The problem: there are no manufacturers – neither in China nor anywhere else – who produce inks that would actually produce similar inks in terms of pigment colour and spectral composition. I once called a manufacturer who advertises that his – already quite expensive – inks could also be used for proofing. When I asked him, he said: “No, no, that’s just for advertising, but of course I would never do that or recommend it, and I don’t know anybody who does that. As for the China inks, he said: “They start at 20 EUR per liter, but you get a different ink with every delivery, depending on where the wholesaler buys. Then they have to re-measure the proofer every time… forget it.” In addition, replacing a clogged print head costs around 2,500 EUR, so the risk is too high. A real proof therefore only works with original, very expensive ink.

2: Using cheap software?

GMG ColorProof, EFI Fiery XF and ORIS Color Tuner are just some of the most important proofing solutions on the market. What they all have in common is that proofing software is rather a niche software, so the programming effort is very high compared to the sales figures. Depending on the size of the output device and the range of functions in terms of verification, spot colour display or proofing on special materials such as transparent foils, etc., the software costs between 5,000 and 10,000 EUR, and in combination with other software products from GMG or Colorlogic it can quickly cost considerably more. Although there are a few low-cost solutions here too, these are usually irrelevant in professional proofing, as they are either not suitable for more than one workstation, or important functions such as spot colour libraries etc. are missing.

Good times: The general meeting 2019 of freieFarbe e.V. in Switzerland

After the association freieFarbe e.V. had met last year in Tübingen for their annual general meeting, this year we met in a rustic hut in the Appenzeller Land, which Peter Jäger from pre2media and Eric A. Soder from pixsource.com had excellently chosen, just like the sunny weather that should accompany us from Friday to Sunday.

freieFarbe e.V. general meeting 2019: Our accommodation in the Swiss mountains

The chairman of the association, Holger Everding from DTP Studio Oldenburg and Jan-Peter Homann from Homann Colormanagement in Berlin arrived in Tübingen on Thursday, and after a first long night full of discussions and a meeting in the Proof.de office on Friday morning around noon, the three of us continued our journey to Switzerland. After a joint dinner with Peter Jäger and Eric A. Soder (from Tübingen, we had taken some Swabian potato salad and my handmade Maultaschen with us the evening before), an evening full of planning and a strategy workshop for the tasks and goals of the next year began. Without question, this evening was also spent discussing, developing, laughing and working creatively until late into the night between Flensburger Pils, Swiss mountain beer and wine in attractive red and light yellow shades.

Paper white from Arctic Paper, Surbalin from Peyer and more added

We have added 140 additional paper white values from Arctic Paper, Peyer, Igepa, Antalis and Mondi. As a result, a total of almost 1400 paper whites are now available in our database. From the company Peyer we have added the colour shades of the Surbalin product range, although we have not covered all surfaces individually here. However, we have now also included other Peyer products such as Peytan, Peydur, Peyprint and Comet in the paper white database. You can find the paper white database at shop.proof.de: https://shop.proof.de/en/info/paper-white.html

How to match the production paper, proof standard and the proof precision of spot colours

Today a customer called who wanted to order a proof of several HKS N spot colours on an uncoated paper. “Which proof profile should I choose? And how exactly can you match my special colours in the proof? I probably have to proof several HKS N red tones in comparison. By the way, the printing is to be done on Fly Cream, a slightly yellowish paper.”

What is the paper white of the production paper?

First of all, I searched with the customer for the production paper in our paper white database. A quick look via full text search revealed that we have measured Fly Cream from Papier Union:

Fly Cream enthält gemäß unseren Messungen keine optischen Aufheller, also "keine OBA". Das LAB Papierweiss liegt bei allen drei Messungen bei rund  LAB 95 / 0,7 / 9,2
According to our measurements, Fly Cream does not contain any optical brighteners, i.e. “faint”. The LAB paper white in all three measurements is around LAB 95 / 0.7 / 9.2

With a B-value in LAB of 9.2, Fly Cream is really not just a little yellowish, as the customer said, but clearly yellowish, chamois, creamy … whatever you want to call it. So it was natural to check the proof profile “ISOUncoatedYellowish”, Fogra 30, to see to what extent the paper white could match.

What is the paper white of the possible proof standard?

Together with the customer we looked up our “paper white of proof profiles” table:

Das Papierweiss des Proofstandards Fogra30, ISOUncoatedYellowish
The paper white of the proof standard Fogra30, ISOUncoatedYellowish in LAB: 95.93 / -0.77 / 3.85

Contrary to the customer’s expectations, the paper white of ISOUncoatedYellowish is not even as yellowish as the paper white of the edition paper Fly cream, which is more yellowish by more than 5 steps on the B axis. So it was clear: PSOUncoated as a brighter-free uncoated paper proof standard is clearly too white, ISOUncoatedYellowish is much more suitable.

On what kind of proof paper will this proof standard be printed?

eciCMYK profile available for proofing

Today we have activated the exchange colour space eciCMYK, Fogra53 for proofing and integrated it into the online shop of proofing.de for ordering. eciCMYK is the colour space for CMYK print production and complements the other Fogra colour spaces, but in contrast to these it does not represent a specific printing process, but is rather “neutral CMYK”. Due to the large gamut of eciCMYK all classical printing processes can be represented, it can be proofed on modern proofing systems without any problems and corresponds in its characteristics to typical CMYK …

Paper white of many paper manufacturers and online printers measured

We spectrally measured the paper white tone and the proportion of optical brighteners of over 1,000 papers of the most important paper manufacturers such as Berberich and Papier Union as well as online printing companies such as Flyeralarm and wir-machen-druck.de. Only a few paper manufacturers currently publish data on paper whiteness and the proportion of optical brighteners in their papers, but only technical indicators such as whiteness according to ISO 2470-2 or CIE ISO 11475. However, designers can hardly record paper whiteness with these values. In addition, it is not …
