Regardless of what we write here in the blog: Sometimes pictures speak louder than words. That’s why we’ve put a short video online that introduces us and our work. It gives you a brief overview of who we are and what drives us. What do you think of our short film? We are looking forward to your feedback!
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/fogra-certification.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.
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.
Today we updated our chat software Livezilla Pro to offer you even more comfort and speed in the chat. Simply contact us directly via chat … a lot of minor details or brief queries can be dealt with quickly and conveniently.
In addition to security updates and performance improvements, the chats should now be even more reliable in every possible browser and PC combination. Uploading and downloading files such as screenshots in the chat history should also be improved.
A word about data protection: We don’t use any supposedly free chat solutions based in Las Vegas, we care about the protection of your data and your anonymity in the chat:
So please don’t be surprised if you already have an order in your shopping cart and then start a chat with us, that we neither see who you are nor what you want to order from us. We only chat with “Guest 0288” or “Guest 6452″… only if you tell us your order number or your name, you will be “recognisable” as a person or company in the chat.
Shortly before Christmas, we initiated a major shop update, and adapted and improved numerous detail functions. But we are especially pleased that the update went without any major disruption for our customers, and that the shop was online and accessible for only a few hours, even though the update had to be carried out at the live shop.
The most important point for us was to update the upload area. The new file upload can now process up to 2GB per file and up to 50 files per article and: The upload now starts automatically, and does not need to be started first. We are thinking about increasing the file limit further here, but we really recommend our customers to simply zip many small files and upload the .zip file before uploading. This helps with the overview, and also helps us in handling.
Another new feature is that now all upload areas of all articles are uploaded in parallel and after successful upload all data is displayed appropriately for the articles. Only after the successful last upload the overview page is updated.
The overview of the loaded data has also improved.
Due to an updated shipping module we have more and more variable shipping methods at our disposal. Thus, starting next year, we will also be able to offer a UPS Express before noon, presumably parallel to the DHL Express before noon.
The most important point for us, however, is that the integration of the external modules has now changed so that we can import updates to the shop without having to touch all external modules at the same time. This will give us a lot of flexibility and allow us to respond even faster to better functions in the future and implement them in the shop.
A lot of changes in the background are security patches and an update to a current PHP version, which makes the shop overall more performant and secure.
Next year we are planning a graphical update of the shop before, which will make the website even clearer and faster.
The ISO 12647-7 proofing standard was revised in November 2016 and the test criteria for FograCert contract proof creation were adapted. We have now incorporated these changed criteria into our proofing system and are now working to the stricter tolerances of the latest ISO 12647-7:2016.
The good news is: you won’t notice that our proofs are now precisely produced according to the latest standards. Why? Quite simply: Because our demands on our proofing system, our FIERY proofing software, our EFI proofing papers and the X-Rite measuring decvices are already so high that all components of our proofing system – and of course our proofs themselves – have been meeting the new criteria of the revised November 2016 standard for years.
The new standard brings the classical formula for the colour distance Delta-E from the traditional definition of 1976 (CIELAB 1976) to the updated version of 2000 (CIEDE2000). Since the values cannot be converted directly, new tolerances for the test report are introduced, which are valid immediately. These new tolerances and new criteria are also the only difference that you will notice on our proof when you take a closer look at it.
Why this change: Fogra used measurements from the 116 Contract Proof Certifications from 2016 to show that the old and new tolerances of the old? These colors have so far had a? E-value that is too high in relation to the visual assessment. The new Delta-E values, on the other hand, are much more “equidistant”, i. e. with the human assessment of the colour distance, which Fogra has also demonstrated in tests.
The deviations of the gray axis and hue are now also determined more precisely, the evaluation of the hue spacing? You can also see this on the test report. The Fogra writes:”Since HC mainly depends on the hue angle, the evaluation of neutral grey or similar colours with sometimes very large differences in brightness and saturation did not yield meaningful results. The measure?Ch now describes the actual distance of a color pair in the CIEa*b* plane and is therefore no longer suitable only for the evaluation of the colorfulness difference of very rich colors.
The ageing tests for proof papers were clarified more clearly with the introduction of the new standard. All certified proof papers undergo the following tests: (more…)
