Adobe has updated its colour picker in the 2019 version. Especially in Adobe InDesign 2019, decimal places are now possible for LAB and CMYK during colour input, which is a long-desired feature especially in the high-end colour area. Up to now it was already possible in Adobe InDesign to enter colour values e.g. in CMYK with decimal places and to write them into the PDF during PDF export, but only integer values were displayed.
In Adobe InDesign 2019, three decimal places can now be entered for LAB and CMYK and can also be read out again. However, these values are not adopted in the automatic labelling of the colour fields, although this can always be adjusted manually.
Also in Adobe Illustrator 2019 CMYK inputs with decimal places are now possible, although only two decimal places are possible here. With LAB, only an integer entry is still possible.
Only Adobe Photoshop still does not allow any decimal places, but only whole numbers, it does not matter whether the file is in 8Bit or 16Bit. This applies equally to LAB, RGB, CMYK and grayscale: In none of the colour systems is a specification with decimal places allowed.
On the last weekend in September the general meeting of the association freieFarbe e.V. took place in Tübingen. From Friday to Sunday, the members worked, discussed, conceived and, as you can see on the picture, ” punted” in and with new products and ideas in the best weather on the Neckar river.
After a meeting with the colour management specialists from GMG on Friday, who support the association with software and proofing media, work continued on the new CIELAB HLC Colour Atlas in the afternoon, to wrap up the day with tarte flambée and wine at Matthias Betz’ house.
On Saturday, the general meeting followed at Lorettoplatz at Proof GmbH, where the past year was discussed and the coming year was touched upon. With the CIELAB HLC Colour Atlas and the DIN SPEC 16699 Open Colour Communication much was reached and accomplished, but numerous ideas need to be evaluated, weighted, financed and worked on.
Present were: From Germany Matthias Betz from Proof GmbH as this year’s host, Jan-Peter Homann from Homann Colormanagement in Berlin, Holger Everding from DTP Studio in Oldenburg and the Swiss Peter Jäger from pre2media in Hombrechtikon, Eric A. Soder from pixsource in Uster and Matteo Baschera from galledia in Zurich.
The fact that also here the conversion does not run completely smoothly, shows up in the data requirements, which recognize beside the new PSOCoatedV3 also a 300% variant of the profile – a legacy from the ISOCoatedV2 300% times, PSOCoatedV3 is present only in a 300% version, a profile PSOCoatedV3 300% does not exist therefore.
Nevertheless, the conversion shows that the new Fogra 51 and Fogra 52 profiles are also increasingly being used in online printing. A replacement of ISOCoatedV2 is still a long way off, the profile is simply too successfully anchored in the market and also well established as a defacto master standard for numerous printing processes in digital printing, trade fair construction, flexo printing and much more, so that this will take several more years. But with every major player in the printing market that advocates the conversion, the spread will increase and the new profiles will also be used in prepress.
We proof more than 50 international proof standards, but there are always one or two standards that we do not yet offer. Often ink manufacturers or paper producers also offer ICC profiles like Aniva or Heaven42 and the Munken, Amber and Arctic paper series from Arctic Paper. Or have you measured a house standard for your printing parameters which you would like to use for proofs? Then please contact us. We will be happy to support you.
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.
Also for us the shop update offers some positive innovations. Following the discontinuation of DHL’s old Intraship service, we can now also create automatic shipping labels for parcels via the new “Send” feature of the DHL Business Customer Portal. Another new feature is that we can now digitally frank address labels for our DIN B4 envelopes using digital stamps and therefore no longer require normal stamps. This is particularly interesting for us when mailing abroad with registered mail, which used to be a tedious process at the online post office, which is now automated. And we can switch between orders more easily.
The next updates are already in planning. Especially the upload area is currently being technically replanned by an external developer, because with the next update the way of embedding extensions in the shop will also change. Probably later in summer the next update will be available as soon as the new modules are available and we have been able to test them thoroughly.
In this DIN SPEC we will define tools and procedures for open and transparent color communication from design to finished product based on CIELAB color values, physical samples according to ISO12647-7 and spectral data in CxF3 format according to ISO 17972.
DIN SPEC describes both the way to create physical samples and CxF spectral data for any CIELAB color values by the user and the basic parameters of an open reference color system, which is available to all users without license costs under a Creative Commons license. The work equipment described in DIN SPEC is particularly suitable for tasks in which colours are defined in design for various production processes and communicated to manufacturing companies by means of physical samples and spectral data. The procedure described in DIN SPEC is intended to enable the production of matt, silk-matt and glossy colour samples on closed unstructured surfaces.
In a way, DIN SPEC is the little brother of the DIN standard. DIN writes: “DIN SPEC is a highly effective marketing instrument which, thanks to the recognized DIN brand, ensures a high level of acceptance among customers and partners. DIN ensures that DIN SPEC does not conflict with existing standards and publishes the standards, even internationally. A DIN SPEC can be the basis for a DIN standard.”
With DIN SPEC 16699 “Open Color Communication” we at freieFarbe e.V. would like to show that with open tools and procedures as well as Creative Commons licenses, in particular the CIELAB standard, ICC-based color management and ISO standards for spectral data, color communication is possible on a professional level.

The CIELAB HLC Colour Atlas offers professional users of colour three decisive advantages:
The ECI writes: “Mainly due to paper differences, the printing condition on today’s SC-B paper types no longer matches the characterization data set FOGRA40 and the profile »SC paper (ECI)«. As a consequence, when printing on SC-B paper, printers face significant problems to achieve the ink solid aim values of »FOGRA40« and the higher saturated colour appearance of »SC Paper« proof prints. In addition new aim values, especially new dot gain curves of the international printing standard ISO12647-2:2013) are reflected in the new printing condition.

After experts such as Christian Piskulla of Cleverprinting have already provocatively pointed out the failure of the new standards – “Scheitern PSOcoated_v3 und die ISO 12647-2:2013?” (Are PSOcoated_v3 and ISO 12647-2:2013 failing?), the new printing standards seem to be spreading in practice at the moment. Two of the four Flyeralarm partner printing houses are now explicitly demanding the new profile, Flyeralarm itself still refers to ISOCoatedV2. However, it is probably only a matter of time before the large online printing companies will also switch to the new standards. Prognosis: If the first one starts, the others will follow.
Two years after the introduction of the new profiles, the Fogra51 and Fogra52 standards have thus arrived on the larger market for the first time and are also actively demanded by printers.
In the proofing sector at least Fogra51 still plays a subordinate role, Fogra39 is still the absolute top dog here. In the area of proofs for uncoated papers, Fogra52 already has a firm place because of the numerous papers with a high proportion of optical brighteners. On many papers, the colour shades of Fogra47/PSOUncoated simply cannot be achieved anymore.
So it seems that the drumming up of the BVDM in particular with regard to new printing conditions has paid off in the long run. If the large market players change over, the small ones will soon follow or will have to follow.
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…
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!
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…)
The colour deviations were calculated by the proofing software on the basis of the measured colour space of the proofing system of proof.de. Therefore in practice there may be deviations. However, it has been shown that almost all PANTONE colours can be simulated quite well in the large colour space of the proofing device.
The smaller the ∆E value, the smaller the colour distance from the PANTONE reference to the proofed PANTONE colour. Higher ∆E values indicate which PANTONE colours can be reproduced in the proof with greater difficulty.

The reason for the 112 new colours is not entirely clear. PANTONE writes vaguely, “112 industry-desired and inspiring spot colours to complement our existing collection” and “The 112 new spot colours are market-relevant, focusing on specific desired colour ranges that offer designers the most advanced and inspiring colour options for creative design application, expression, communication and specification.”
Let’s be honest: Positively phrased, this does not sound like a convincing colourimetric concept. So it is not surprising that on the American website there is a dazzling image film with designers who really wanted these colours. Due to a lack of relevance this film was probably not even offered in German …
Still, the new colours are here, and designers, graphic artists and printers are called upon to deal with them. The libraries in the PANTONE Color Manager are already updated, and the colours are also available online in PANTONE.
At the moment we do not have the colours available in LAB via FIERY in the system, but due to the published colour values we can proof the colours in sRGB or CMYK variants. We have already completed a first order – so the colours seem to be not completely irrelevant for the industry after all.
Since today we offer proofs in ISONewspaper26v5.
No further documentation was available at that point on the IDEAlliance Website. The ICC files can be downloaded in a ZIP file here:
In each download you will also find PDF files with explanations and notes on the respective profiles and characterisation data. On the Fogra page you will also find the current colour values for the UGRA/Fogra Media Wedges CMYK 3.0 for the new printing conditions PSO Coated V3 and PSO Uncoated V3.
The Proof GmbH has thus reaffirmed it’s quality by the strict criteria of Fogra. The tests Fogra conducted went far beyond the pure colorimetric readout of a media wedge. The special proofs for Fogra were evaluated among the following criteria:
The color matching our proofs submitted for the test was confirmed by Fogra with date of September 24, 2015. The Proof GmbH is thus the world’s first company that has certification for the production of contract proofs on a Fogra 51 and Fogra 52.
We are very pleased that our preparation and the efforts of the past few months were rewarded by a successful certification. You can order Fogra51/52 proofs in our proofing shop Order Fogra 51 / Fogra 52 Proofs (PSOCoatedV3 and PSOUncoatedV3).

On Wednesday, the 30th of September 2015 from 10 o’clock representatives of the associations will introduce in the university the innovations, Karl Michael Meinecke wrote of the ECI mailing list.
In this kick-off the new, jointly developed printing conditions and to implement the ISO 12647-2:2013 are presented to printing and media professionals. Attendance is expected to be free, but registration with name and company to the email address email@example.com is requested. The event takes place at the HdM in auditorium i003 in the Nobel Straße 10, D-70569 Stuttgart (Vaihingen) in the Stuttgart Media University.
Fogra51 and Fogra52: A difficult start
The launch of Fogra51 and Fogra52 had been marked by delays and disruptions. Large series of measurements had to be discarded after testing, measurement technology as the new SpectroProofer ILS 30 or new proofing papers were delivered only with great delay. Several seminars on how to manage the change to the new ISO standards in the Fogra are running since late last year with numerous participants in full swing – only the new standards were still not in sight. Now there is at least the kick-off date at the end of September in sight.
Cirtainly, all involved representatives of associations and interested companies were often reminded of the negative model of the US standardization bodies:
The IDEAlliance had presented in 2013 probably too hastily developed new printing conditions for GRACol 2013 and SWOP 2013, but so far they hardly play any role in practice. Why? Even the IDEAlliance open most their publications on the new standards with the tenor: “If you are not extremely color-critical, there is no reason to change from the old standards to the new ones … Conclusion: Please stay with their established, old workflow with profiles from 2006 … we are currently working on numerous ‘supplements’ …”
PSOCoatedV3 and PSOUncoatedV3: What definitely comes
But it is clear: The new standards will bring many changes to companies in printing and prepress: The individual changes in detail: (more…)
The release was perhaps a bit too early – even the Americans feel uneasy. So several documents of IDEAlliance regarding GRACoL 2013 and GRACoL 2006 almost discourages a necessity of a change towards the new profiles.
Ron Ellis and Don Hutcheson wrote: “The few minor changes are barely visible in most subject matter and should not significantly affect printers, designers or print buyers. […] In fact the differences are smaller than the typical variation between two good offset press runs “Not even image data or proofs must be adapted to the new standards”. The really good news Is that legacy image files and proofs produced using GRACoL 2006 Should not need to be adjusted or converted for printing or proofing to GRACoL 2013 (and vice-versa), except in rare situations.” GRACoL 2013 Guidelines
LAB values of the primary colors, white paper and more have of course changed, therefore the reluctance can be explained only by a degree of uncertainty, as the Fogra and the ECI will implement their new Printing Conditions Fogra51 and Fogra52 at the end of September 2015. But ont thing is for shure: When it comes to dot gain and paper white, the American profiles are noticeably different from the new PSOCoated standards of the German Fogra.
