Heaven42
The absolute white tone opens up the greatest scope of colours for design and printing afforded by any coated paper worldwide. The perfect foundation for extreme contrasts and combination with ultra white natural papers. The absolutely white paper shade of heaven 42 impacts on the printing process as well as on the pre-press stage. With the same colouring and dot gain, the printed image can look significantly colder if separation remains unchanged (e.g. with
ICC-profile “IsoCoated_v2”).
We proof Heaven42 on proof paper with optical brighteners and measure the Proof in M1 Standard. Please note: Our Heaven42 proofs represent a good simulation of the original Heaven42 ICC Profile, but are not – as an ISOcoatedv2 Proof – colouraccurate and legally binding.

First online printers switch to PSOCoatedV3 and PSOUncoatedV3
With DieDruckerei.de, the first well-known online printer has switched to PSOCoatedV3 and PSOUncoatedV3. A sign that almost exactly three years after the new Fogra51/52 standards appeared, they are increasingly being used in production and as a requirement for printers to produce data.
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.
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.
What is the UGRA-Fogra Media Wedge 3.0 used for?
Every print shop in Germany adheres to a predefined standard, the process standard offset printing. This standard defines target and tolerance values for printed products. In order to prove that your proof delivered to the print shop meets these standards or is within the tolerances, the media wedge is measured and the values analysed in case of doubt – i.e. in case of a streak. If these measured values are correct, the print shop is obliged to adhere to and achieve these values.
Practice generally shows the following: If you want to have a 4-page image brochure proofed and printed, it is usually sufficient to have a single media wedge printed under the 4 pages. If the media wedge is also provided with a test report, the colour accuracy for the print shop is directly confirmed as a guideline.
However, if you want to be on the safe side, have a separate media wedge (including test report) printed under each of the 4 pages of your brochure.
Standardized light and metamerism effect
A proof is only as good as the light under which it is viewed. Just going to the window or switching on the light at dusk is useless: between December and July, between 8 am and 8 pm, between cloudy and sunny days there is a huge difference in the lighting, which makes any colour evaluation impossible. And if you switch on the light, you normally switch on a bulb with 2700 Kelvin – or even worse: an energy-saving neon bulb that somehow shines in any spectra… a disaster!
The reasons for metamerism effects (in short: that two colors look identical under one light, but completely different under another) lie in the different printing technologies. Colors that look the same under a light bulb can suddenly look very different under a neon tube.
In recent years, ink-based digital proofs have established themselves in the proofing sector. Because it is printed in ink, specially coated paper must be used, which is not in any way similar to the subsequent production run. Anyone who has ever tried to print on glossy coated paper with an inkjet printer knows: the ink never lasts! Metamerism is therefore always involved when a proof is to be compared with offset printing.
The light under which proof and production run are viewed is particularly important.
ISO 3664 regulates standardized light, which is important for viewing proofs and prints. D50 is no longer D50: The International Lighting Commission CIE has revised ISO 3664 in recent years and adapted it to today’s circumstances. If UV components used to be strictly prohibited, they are now part of the standard. In the past, the focus was on consistency between slide and print, while today monitor, digital proof and offset printing are important. Therefore, proofs must always be viewed under D50 Standardized Light, so that they are really “colour-binding” in their perception.
If you want to check metamerism effects, we recommend the UGRA colour temperature indicator. With these strips, metamerism effects can be checked very quickly and clearly.
D50 is not the same as D50: Standardized light and ISO3664:2009
Since 2009, printers and proofing service providers have increasingly encountered a new D50 lighting standard: ISO 3664:2009, which defines how the new D50 standardized light, under which proofs and print products are to be evaluated, looks like. The new standard light contains UV components that address the optical brighteners that are frequently used in offset papers nowadays.
The result: next to a bluish-white glowing sheet in the pressroom, there is a yellowish-pale proof.
What is the reason for this? The standard came sort of as a surprise and was poorly communicated within the industry. All proofing substrates available from proofing service providers contain no or almost no optical brighteners – this was previously a requirement. And under the old D50 standardized light – which did not contain any UV components – the proof and production run looked identical, since the optical brighteners were not addressed in the production run. Proofing and production printing can no longer be compared on all new presses that are already equipped with light tubes of the new standard: This looks completely different, the differences in paper white are absolutely obvious.
Printers and proofing service providers have mostly replaced the old tubes with new ones. However, this is often a complex topic: The old diffusing screens, which are mounted in front of the neon tubes, had so far predominantly once again installed UV filtering in order to ensure that completely no UV components get through. If new ISO 3664:2009 tubes with a defined amount of UV components are mounted behind the diffusors, unfortunately exactly this component is missing in front of the diffusor again… So there are some extra costs for the printers.
In the meantime with M1 and the new proofing Standards Fogra51 upwards, many proofing papers with brighteners havel been launched on the market so that proof and run can be compared cleanly again in the pressroom.
Embed profiles for proofing? Yes or No?
The question often arises whether color profiles should be embedded in the PDF files for proofing.
To answer the question, you have to get some answers: The proof should simulate the subsequent offset printing. For offset printing, with few exceptions, the imagesetters have been configured so that a 70% black in the file is displayed as 70% black on the printing plate, no matter what profile was specified in the file. It didn’t matter whether it was coated paper or uncoated paper: 70% in the file corresponded to 70% on the plate, the choice of the paper printed on resulted in the colour representation.
The proof has also adapted to this: Most proofing service providers ignore embedded profiles, as long as the data is in CMYK and do the same as their print colleagues. Even with grayscale, the profiles are usually ignored and the grayscale is simply assigned to the CMYK black channel. Thus all CMYK and grayscale data are simply interpreted as if they had been created in the output color space. If “ISOCoated V2” is proofed, all images are treated as such, and if “PSOUncoated” is proofed, then the CMYK images are created in this color space.
This is excellent for the majority of files to be proofed. Only RGB colors contained in the data are problematic.
Since the RGB color space is considerably larger than most CMYK color spaces, it must be clear from which color space to convert to CMYK according to which criteria. Most proofing service providers specify a color space from which they convert by default if no RGB color space is defined. This can lead to difficulties: For example, many proof studios choose AdobeRGB as color space because it is large and optimized for offset printing; however, most images from digital cameras come from sRGB and these color spaces differ considerably. Therefore, it is important that the RGB color space and the rendering intend is embedded for a proof, otherwise the proofing software normally selects a color space for conversion to the CMYK color space to be proofed; and this color space is possibly not the one in which the data has be created.
Softproof – opportunity or risk?
Softproof means: The correct color display of a printed product on a monitor. Both a standardized print, e.g. according to process standard offset printing, can be simulated – e.g. a later offset print according to ISOCoatedV2 can be simulated correctly in colour on the screen – and the output on digital terminals such as LFP systems in advertising technology.
From a technical point of view, soft proofs are now well controllable. The monitor technology is advanced enough to provide excellent displays with a high color gamut and consistent illumination even for a few hundred euros. For example, monitors in two branches of a company can be coordinated in such a way that the result displayed on the monitors corresponds exactly to each other at both locations, i.e. one image editor in Hamburg and one in Munich can talk about retouching the same file.
The problem: The fact that the two monitors emit the identical color and light result can be precisely controlled. The fact that the colleague in Hamburg is looking at the foggy Alster lake at a northern window, while the colleague in Munich moved the monitor to a southern window in the direction of the Isar river in sunshine, already shows the problem: The environment variables under which the softproof is viewed are not identical.
It is even more difficult when the soft proof is to be used in the pressroom to coordinate the production run. Many companies such as JUST offer modern solutions that can provide a soft proof directly at the press. However, the problem remains that the soft proof should be considered to be less than 10% away of the brightness of the press. While 2000 lux brightness was previously the standard for printers, JUST now writes: “The comparison of soft proofs on monitors with prints and hard proofs is regulated in accordance with ISO 12646. The light conditions basically correspond to ISO 3664, but the brightness must be adjusted to the limited luminance of the monitor, which ideally is > 120 cd/m². ”
Two scenarios therefore arise at the printing press: Either the printer is “in the light” and can then match the print with a contract proof printed on paper, or it is “in the dark” and can match the print with the soft proof. The difficulty of matching paper and monitor – and these are two completely different and difficult to compare media – is compounded by the difficulty of the printer having to dim the light at the press by up to a factor of 10 to be able to match both a contract proof and a soft proof at the same workstation. From today’s point of view, this does not really seem practicable.
Conclusion: The soft proof is on the advance and will certainly sooner or later displace the classic contract proof from the market for reasons of speed and cost. However, due to the great technical lighting and haptic differences between the monitor and the illuminated sheet of paper, a widespread introduction is still a long way off. After all, anyone who has ever performed a color match on a printing press can imagine that a match to the contract proof on the one hand and to a soft proof monitor on the other hand is difficult to imagine at the same time. The contract proof will therefore also have to remain the first choice in the near future in order to be able to carry out colour-accurate proofing of the printing result in the pressroom.
ISO12647… and then what? On the further development of the ProcessStandard Offset Printing
Fogra is currently working with great commitment on modernising ISO 12647 and adapting it to current environmental conditions.
Important innovations of the reformed ISO 12647 will be:
- Innovations regarding paper types (PT)
- New tone value increases
- For proofing: New papers with optical brighteners
Why is ISO 12647 being revised? Environmental conditions have changed significantly at three central points since the last revision in 2004.
Papertypes
The previous paper types 3 and 5 with the paper whites defined in 2004 are hardly available on the market today. Even picture printing papers today show a much stronger blue colouration than just a few years ago. In addition, the revision of D50 in 2009 means that the lighting in the pressrooms now also contains considerably more UV than before 2009, which has caused problems in the matching of proofs without optical brighteners compared to papers with a high proportion of brighteners. Instead of the previous 5 paper types, there will probably now be 8 new paper types which also differentiate between glossy and matte picture printing paper:
- PT1: Coated picture printing paper (Premium coated)
- PT2: Brightened, coated picture printing paper (Improved coated)
- PT3: Glossy coated magazine paper (Standard coated glossy)
- PT4: Matte coated magazine paper (standard coated mat)
- PT5: Wood free uncoated
- PT6: Supercalendered, uncoated
- PT7: Improved uncoated paper
- PT8: Standard uncoated
Based on these eight types of paper, a total of 16 printing conditions are created by using frequency modulated non-periodic screening and conventional periodic screening.

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:
- Color accuracy of the Ugra / Fogra media wedge CMYK 3
- Overall color accuracy and gamut
- Uniformity and homogeneity of the proofsProof GmbH has again been certified by Fogra in September 2015, this time for the standards Fogra 51 (PSOCoated_v3), Fogra 52 (PSOuncoated_v3) and Fogra 39 (ISOcoatedv2).
- Color and gloss of the proofing papers used
- Tonal range and tonality
- Register and resolution
- Status information on the proof
- Tonal values
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).

New Proof papers for Fogra51 and Fogra52 in use
Three weeks ago, we have introduced two new proofing papers for the proof of Fogra 51 and Fogra 52 Beta standard and other color standards, that require proof papers with optical brighteners:
EFI Proof Paper 8245 OBA Semimatte
EFI Proof Paper 8175 OBA Matte
A proof for coated papers with optical brighteners, we offer on semi matte EFI 8245 OBA semimatte with 245 gr / sqm. The EFI Proof Paper 8245OBA Semimatte has been specifically designed for proofing white and brightened, coated papers. The white point of this semi matte paper is very close to the values of the FOGRA51 profile and thus allows proofing of FOGRA51 with virtually no paper white simulation at all. It is also well suited for simulating paper conditions PC1 according to ISO 12647-2:-2013.
EFI Proof Paper 8245 OBA Semimatt
Weight: 245 g / sqm
Thickness: 245 microns
Opacity:> 95%
Gloss: 22%
CIE L * a * b * (M0): 95.8 | 0.9 | -4.3
CIE L * a * b * (M1): 96.0 | 1.1 | -5.6
For Proofs on uncoated papers with optical brighteners, we offer proofing on matte EFI 8175 OBA matte with 175gr / sqm. The EFI Proof Paper 8175OBA Matte has been specifically designed for uncoated proof standards. It is highly brightened and very suitable for proofing of Fogra52.
EFI Proof Paper 8175 OBA Matte
Weight: 175 g / m²

Fogra Fogra 51 and 52: No Start in sight.
Fogra Fogra 51 and 52, optical brighteners and the new standards for offset printing and proofing are currently on everyone’s lips. In the proof area we still see only announcements and beta versions, but no real solutionsby now. In 2013 the reorganization of ISO 12647-2 was adopted for offset printing, but according to ECI the earliest “expected recommendation on the implementation of the new ISO 12647-2 as well as the provision of appropriate handouts and instruments’ will be in 2015. The current status of Fogra 51 and Fogra 52 from our perspective:
Color profiles:
- Fogra Fogra 51 and 52 have completed the beta phase at the Fogra in May 2014 and were forwarded to the ECI. The there in the project “fred15” compiled information and downloads are but from March, July to October 2014, but since then there has been no more news on the new standards. So there is currently no date for the release of the final profiles, handouts and tools foreseeable. Fogra, ECI, bvdm and UGRA continue to work together on the new standards.
Proof Papers:
- ONE Technologies announced in May 2014, the certified proofing paper “ONE Proof Paper 51 SATIN” on … that in November is not yet available anywhere.
- GMG announced in October, the proofing paper “GMG Proof semimatte 250 OBA”, which to this day is also available anywhere.
- Also working on new proofing substrates is EFI, but naming, pricing and release dates are not known.
Measuring technology:
- Epson announced in August to deliver from 1 September 2014 all Epson SpectroProofer measuring devices with the new measuring head ILS 30 only. Unfortunately, the new SpectroProofer is not yet commercially available as an accessory.
- While all previous sources reported that the new SpectroProofer – Although Fogra 51 and 52, ie M1 and M2 capable, can not measure ISOcoatedv2 or M0. EFI with Fiery XF 6.1 and the SpectroProofer ILS 30 support all measurement modes, ie Fogra 51 and 52 and ISOcoatedv2 simultaneously … unfortunately is neither Fiery XF 6.1. previously available nor the SpectroProofer … but according to EFI they are currently testing all 3 modes … M0, M1 and M2 with the new SpectroProofer … that sounds promising.

Proof GmbH: Fogra certified for ISOcoatedv2 (Fogra 39) and PSOUncoated (Fogra 47)
The Proof GmbH has again successfully completed Fogra certification for the production of contract proofs – Contract Proof Creation.
The certification proofs have been produced both on EPSON 7900 and EPSON 9900 proof printers with SpectroProofer measuring instruments. Our two proofing papers were included in the certification process. Proof GmbH is therefore certified for the most frequently used Proofing Standards.
The requirements for the Fogra certification go far beyond simply measuring the media wedge. So the proofs are analyzed according to the following criteria:
- Compliance with the tolerances of the Fogra Media Wedge CMYK 3
- Determination of color accuracy [ISO 12642-2 test chart], the color gamut and gray balance
- Gloss measurement in accordance with ISO 8254-1 [TAPPI]
- Tone value
- Register and resolution
- Status information
- Tone value
- homogeneity
In parallel to the measurements, control measurements were carried out with a second X-Rite meter in order to eliminate measurement errors.
The conclusion of the Fogra: “The proofs of the company Proof GmbH are as color accurate and binding in the following combinations:
1. Fogra 39 / ISOCoatedV2
Software Fiery XF 5.2.2
Proofing Substrate: EFI Gravure Proof Paper 4245
EPSON Stylus Pro 7900
Fogra 39
2. Fogra 47 / PSOUncoated
Software Fiery XF 5.2.2
Proofing Substrate: EFI Proof Paper 9120 XF matt
Epson Stylus Pro 9900
Fogra 47

Fogra 51 and 52: The new printing conditions start in September 2015
With long delay, the new printing conditions Fogra Fogra 51 and 52 – PSOCoatedV3 and PSOUncoatedV3 – will be presented at the end of September and finally come into practice. The German bvdm invites together with Fogra and ECI to a joint “kick-off” of the new printing conditions in the “Hochschule der Medien” in Stuttgart.
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 ks@bvdm-online.de 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…)
Two years after publication: Large printing companies switch to Fogra 51 and 52
It seems that by the end of 2017 the new standards PSOCoatedV3 and PSOUncoatedV3 are finally arriving on the wider printing market. At least with the printing company Thieme and – as of today – Schleunungdruck, two major operators in the market and Flyeralarm partners have switched to the new standards.
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.
Fogra 54 – PSO SC-B Paper v3 – published and available for proofing
Recently, Fogra provided the first web offset printing condition based on the new ISO 12647-2:2013 with the printing condition FOGRA54. Fogra 54 describes standardised offset printing in AM screen (48-70’cm) on supercalendered B-substance material (SC-B) with mineral oil-free printing inks.
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.
Proofs according to PSO SC-B Paper v3 can now be ordered directly from our shop.

How colour-accurate are proofs?
A proof is prepared according to the currently valid ISO standard 12647-7 and is legally binding with a UGRA-Fogra media wedge and measurement report.
How does this check work?
If you need a proof with UGRA/Fogra Media Wedge CMYK V3.0, there are two ways to add the test report to your data.
- With proofing devices in which a measuring device is integrated, the media wedge with 3×24 standardised colour fields is printed directly under the proof data. This media wedge is driven directly in the proofing device to a kind of “hair dryer” in the measuring device and dried there. After a few minutes of drying, the media wedge continues and is measured directly in the proofer. This takes a few minutes. The measured values determined in this way are returned to the proof server and evaluated there. If the colour values are correct and within the tolerances of the strict ISO standard, a test report of the measurement is then printed directly under the media wedge, which guarantees you colour accuracy in accordance with the process standard offset printing.
- For proofing devices without integrated measuring device, only the standardized media wedge is printed under the proof data. A check takes place subsequently and outside the proof printer. The media wedge is then measured with an external measuring device and the target and tolerance values are output to a label printer. This label is then stuck directly under the media wedge.
What is the advantage of automated creation and checking of the media wedge directly in the proofing device?
- Measurement is automated directly after proof printing, measurement errors due to manual operating errors are excluded. Since the test report is not subsequently attached, as is often still the case, manipulation is impossible.
Further information on the test report, the media wedge and on the work and responsibility of UGRA/Fogra can be found at www.ugra.ch and www.fogra.org.
Fogra 51 and Fogra 52 Beta Proofs available
By switching to the new Fiery XF 6.1 and the use of the new X-Rite SpectroProofer ILS-30 measuring instruments, we are now able to proof the current beta versions of the new printing standards Fogra 51 and Fogra 52.
Since the current proofing profiles are available only in preliminary beta versions, the versions are of course not color binding and legally binding. Nevertheless, interested agencies and printers can get a picture of the current state of development and evaluate the coming changes of the OBA proofing papers used better match the colors of the new proofing standards.
