DIN SPEC 16699 “Open colour communication” published

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.

DIN SPEC 16699 Open Color Communication Final Meeting Berlin. From left to right: Eric A. Soder, Jan-Peter Homann, Matthias Betz, Holger Everding

 

Last Monday, the authors Jan-Peter Homann, Holger Everding, Eric A. Soder and Matthias Betz took another milestone in the direction of free color communication in a final meeting at the German Institute for Standardization – DIN in Berlin: The last open points of DIN SPEC 16699 “Open Colour Communication” were discussed and approved. Now only the English version by Matthias Betz and Eric A. Soder and the final implementation and approval by DIN are missing. It is expected that DIN SPEC will be available for download in August. It is published free of charge as PAS – Publicly Available Specification by DIN in German and English.

In this DIN-SPEC we describe a procedure for precise color communication and color sample creation on the basis of open standards such as CIELAB, HLC, ICC and CXF file formats. We work with mathematical color models, high-precision color samples and exact spectral data as a basis for ink formulation at color manufacturers and service providers. Instead of mutually incompatible commercial standards, we show an open, and open-source approach to high-precision color communication.

Besides the DIN SPEC we are working at full speed on new projects and ideas and on different new versions of our free colour CIELAB HLC Colour Atlas.

CIELAB HLC Colour Atlas available in the Proof.de Shop

It has taken almost a year, but we are all the more pleased now: The “CIELAB HLC Colour Atlas” is completed and can be ordered in our shop. The HLC Colour Atlas is a open source, high-precision colour system based on open standards.

The CIELAB HLC Colour Atlas offers professional users of colour three decisive advantages:

  • The CIELAB HLC colour atlas is based on open, non-proprietary standards that are free of copyrights and trademarks.
  • The colour atlas with all components is available to all users free of charge online and can be downloaded, used and passed on directly.
    It is released under an OpenSource Creative Commons license.
  • The printed reference of the CIELAB HLC colour atlas impresses with outstanding precision and, unlike some commercial products, the colour accuracy is extremely high with a DeltaE00 median of 0.3 and an average DeltaE00 of 0.5. In most cases, the deviation from the ideal colour reference and colour differences between two colour atlases can be measured, but not perceived by the human eye. Each atlas is produced on our best Fogra-certified high-end proofing printer on Fogra-certified paper. Each copy is delivered with an individual, colourimetric test report in accordance with ISO 12647-7:2016 to document the colour accuracy of each individual colour atlas.

Proof GmbH is a partner of FreieFarbe e. V.

freeColor e. V. is a consortium of German and Swiss color experts who work to produce consistent color in all areas of application. Sounds reasonable? Exactly. That is the issue that is of central importance to our proofing customers. Therefore we are currently working in a project with the colleagues of FreieFarbe e. V. and are now also as Proof GmbH member and partner of FreieFarbe e. V.

FreeColor relies on open standards such as LAB and HLC, which have long been integrated in computer software and want to show: the computer is an ideal tool for color, it can make color free! The association FreieFarbe e. V. aims to promote colour communication without pursuing commercial goals.

freeColor e. V. would like to promote developments that…

  • Make coulor calculable
  • Make colour applicably
  • Make ink systems comparable
  • Simplify color communication
  • Have no license costs
  • Give Tips and hints for a correct cross-media colour workflow
  • make the multiple mysteries of color understandable

In recent months, Holger Everding, Peter Jäger, Eric A. Soder and Jan-Peter Homann have developed a completely new approach to this, which we were able to develop together with our colleagues into a product that we will present shortly.

We would like to take this opportunity to point out a great feature of the website of FreieFarbe. de: The colour database: Here you can look up the most important colour values for more than 300 colour systems and calculate colour comparisons of all kinds.

For the work within the association FreieFarbe e. V. the association is always looking for competent companions. If you, like us, are touched by the subject of colour in a variety of ways, there are many opportunities at fF to contribute with your knowledge and strengths. If you feel like our good cause, please contact us!
