We have found a more environmentally friendly parcel sticker for our brown shipping boxes: Instead of a classic PVC sticker, we can now save the environment a little plastic with a paper label produced in offset printing, without compromising on quality and appearance. Admittedly, perhaps not a big step. But every small contribution helps to save our environment a little bit.
We have always used electricity from 100% hydroelectric power, print invoices and letters using energy-saving inkjet printing and have switched our IT to increasingly energy-saving computers, servers and NAS devices.
In addition, for the past two years we have been participating in the German Packaging Act through our partner Veolia, with the aim of minimising the impact of packaging waste on the environment in Germany.
Our annual disposal contribution serves to implement Directive 94/62/EC on packaging and packaging waste. The aim is to further increase recycling rates in Germany.
Proof GmbH is a member of Fogra – Forschungsinstitut für Medientechnologien e.V.. Why? In recent years, we have been able to draw on the support of Fogra with numerous projects, or work together with Fogra, for example for Fogra58 beta – Textile-RGB (where Matthias Betz was also able to report on our experiences as a speaker at the Fogra Colour Management Symposium 2020 in Munich as part of the presentation “Proofing of Fogra58beta”) or have contributed test prints and proofs to the research project “11.004L – Improving the printability and readability of bar and 2D codes in inkjet printing”.
In addition, we have been certified by Fogra every year since 2013 for the production of proofs (https://shop.proof.de/en/info/fogracertification.html) and are very grateful for the services of Fogra, which confirm the quality of our proofs every year, also externally.
Our most important contact person, Dr. Andreas Kraushaar, has often promoted membership to us, and now we have actually taken the step, although we still think that the membership fee is poorly structured, especially for small companies like Proof GmbH (companies with 1-100 employees pay the same membership fee) and we would like to see a more favourable entry. But on the other hand it is true: Fogra with its expertise, its competence and its always competent, helpful, quick and fit contact persons like Andi Kraushaar, Yuan Li and many more also deserves the support of companies that benefit from Fogra’s activities like we do.
We would therefore like to thank Fogra for all the support we have received and knowledge we have gained over the years. From now on, we are a member of Fogra and look forward to many more discussions, projects, ideas and initiatives.
For whatever reason: December is traditionally the month in which we make the most important new acquisitions. In order not to break with this tradition, the new proof printer generation from EPSON moved in with us this year: The SureColor SC-P9500 Spectroproofer.
Unpacking traditionally has to be done in front of the door, we wouldn’t be able to get the printer into the office on the two-metre-long pallet, but once it’s on rollers, it works fine.
The new SureColor P9500 complements our range of SureColor 7000 and 9000 proof printers and, above all, hopefully brings us a further plus in speed, especially for larger jobs. Thanks to a newly developed and now fully loaded print head with 12 inks with up to 800 nozzles each, it is said to print up to 2.4 times faster than our other proof printers, which is particularly advantageous for large proof volumes.
We are currently still in the process of measuring the large number of media we use on the new printer and gaining experience with the new proof printer. Many of the “advantages” are not really relevant for us, as we have very specific requirements in proof printing. In terms of gamut, i.e. the maximum colour space that can be achieved, we were unfortunately unable to determine any real gain. According to our measurements, the colour space has changed marginally compared to the previous proof printers, but not really increased.
For example: Admittedly, the printer prints much faster than our other printers. But in return, it takes much longer to transport the proof paper to the fans for drying, and the subsequent measurement of the media wedge also takes longer than on the 7000 and 9000 systems. For an A4 proof with media wedge and test report, the 9500 is only 8 seconds faster, taking just over 8 minutes. In other words, the higher print speed is almost completely lost in other areas.
Therefore, A4 proofs will not be the domain of this printer, but rather we will try to proof the larger formats on the 9500, where the speed advantage comes into play more.
This reminds me a little of the upgrade to Fiery 7, which was supposed to be up to 5 times faster than the previous version with FastRIP technology. In fact, the FastRIP technology was and is so error-prone that we were never able to use it, as we felt that every 20th job was processed incorrectly or could not be processed at all. On the other hand, with the version upgrade, the entire proofing software became considerably slower … So for us as non-FastRIP users, all that was left on average was a slower system.
And so we are still making our experiences with the new proof printer. The first conclusion we can draw is that many things are better, some are worse and some are simply different. The fact that the printer is still quite new is also evident from the fact that new media updates are constantly being added. We have already run some good jobs through the printer and it has not disappointed us. In this respect, the first conclusion looks fairly optimistic.
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 have also been certified for the representation of spot colours ("Spot-cert"), and in 2020 we were the first company ever to add the Fogra-59 certification:
The quality of our prints and our spot colour reproduction of PANTONE colours has been confirmed to us by Fogra for all four proof standards.
We have implemented the new certifications on the current software revision Fiery XF 7.1.3 and on the papers EFI Gravure Proof Paper 4245 Semimatt, EFI Proof Paper 8245OBA Semimatt and EFI Proof Paper 8175OBA Matt.
A few days ago, our DIN SPEC 16699 "Open Colour Communication" was published and is now available for free download from DIN's Beuth-Verlag.
Matthias Betz from Proof GmbH, Holger Everding from DTP Studio Oldenburg, Jan-Peter Homann from Homann Colormanagement in Berlin and Eric. A Soder from Pixsource in Switzerland, all members of the association freieFarbe e.V., have shown in the bilingual DIN specification a way to create high-precision color samples on the basis of open source, license-free standards and have shown ways for cross-media color communication.
The 44-page PDF is bilingual in German and English and can be ordered directly from Beuth Verlag, which distributes the DIN standards in Germany, and downloaded free of charge after a short registration.
In general, the paper white in a proof is precisely defined in the proof standard and is also measured in every test report.
For PSOUncoated it is 95.00 / 0.00 / -2.00 in CIELAB and for PSOUncoatedV3 it is 93.50 / 2.50 / -10.00, i.e. slightly darker (93.50 instead of 95.00 for brightness L) and significantly bluer (-10.00 instead of -2.00 on the B axis, i.e. the blue-yellow axis in the blue direction).
Recycling papers differ not only greatly from type to type in the area of paper white, but even from batch to batch. So if a printing company orders the same recycling paper in January and in February, the paper mill may well deliver a slightly different white value of the paper, as the paper white of course depends strongly on the recycled paper qualities used for production.
A colour-binding proof for recycling paper is therefore not possible, as no standard has ever been worked out due to the different paper qualities and white tones.
It is recommended for the proof to choose a classic proof standard such as PSOUncoated / Fogra 47, which shows a rather neutral, unbrightened paper white in the proof. Place one side of the recycled paper next to the proof and mentally transfer the colour of the proof to the white tone of your recycled paper. This way you can imagine the later printing result quite well.
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 possible to read from these data whether and what proportion of optical brighteners the paper has.
Example above: Spectral data comparison of Antalis Coqueror CX 22 white for the measurement standards M0 and M1. Below you can also see the color deviation in Delta-E00 of 1.97 and the two paper white values in LAB and LCH.

We have therefore measured the most important papers and dyes of all central paper producers and paper distributors as well as online printers in the three measurement standards M0, M1 and M2. From the difference in the paper whiteness of the two measurements M2 (UV cut without UV portion) and M1 (ISO 3664:2009 with noticeable UV portion), we determined the color distance on the yellow-blue axis of LAB in Delta-b and derived from this the proportion of optical brighteners according to Delta-B according to ISO 15397 and evaluated it.
Parallel to the images of the spectra, we have also provided spectral data in CGATS format for the measurement modes M0, M1 and M2, which can be downloaded for any paper. These values can be used, for example, in proofing software to calculate a paper white simulation for a specific production paper.
