New certified proof papers at proof.de
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
New in the Proof Shop: Separate invoice email
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
Annual Conference of the German Society for Colour Science in Darmstadt
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
MYIRO-9: New Spectrophotometer from KonicaMinolta in action
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

New PANTONE Formula Guides with incorrect ink formulations
Several errors have crept into the new PANTONE 2023 fan decks. In both the PANTONE Solid Coated and the Solid Uncoated color fans, there are colours for which the new ink formulations are incorrect. In the PANTONE Formula Guide Solid Coated fan 2023, PANTONE 107 C and PANTONE 108 C have absolutely identical ink recipes, as well as PANTONE 113 C and PANTONE 114 C. As the colors differ, this cannot be the correct. Several errors in the PANTONE Solid Uncoated fan 2023 In the PANTONE Solid Uncoated fan 2023 … read more
Precise proofing of tonal values of spot colours
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

Proof GmbH 2025 once again Fogra and Fogra “Spot Cert” certified
This year we once again created proofs for Fogra certification and sent them to Munich-Aschheim for testing.

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
PANTONE surveys users online about product and service direction
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
