Proof. de offers proofs according to the latest tolerance criteria of ISO 12647-7:2016

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.

Why hardly anything changes for our Proof customers

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 most important new features of the new Proof Norm in brief

1. colour accuracy

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.

2. durability of proofing papers

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:

room temperature
(24 h at 25° C and 25% rel. humidity)
hot and humid environment
(24 h at 40° C and 80% rel. humidity)
dry storage
(1 week at 40° C and 10 % rel. humidity)
fastness to light
(at least level 3 of ISO 12040)
A proof now has to pass through all of the above tests without any difficulty, whereby it is now regulated that a new proof is used for each test, i. e. not a copy has to pass all tests one after the other.

3rd Optical Brightning Agents (OBAs)

Three years ago, the offset standard already included the categorisation of the optical brightener content in the offset standard, the proofing standard is now following suit and uses the same classification. The brightener content of the proof paper should be similar to that of the used support paper or belong to the same category, similar to the gloss of the proof paper.

4. Spot colours such as PANTONE and HKS

The new revision of the standard also includes criteria for the evaluation of spot colours such as PANTONE, HKS or TOYO. These can now optionally be evaluated within the standard, which is then done via a separate media wedge with test report. For measured spot colours, the tolerance for colour deviation must be within Delta-E 2.5.

In the example shown here, a proof file consisting of colored squares with 4 additional PANTONE spot colors is output: PANTONE 7441 C, PANTONE 2995 C, PANTONE Bright Green C and PANTONE ORANGE 021 C. These spot colors are recognized by the RIP and assigned to the respective internal color values, which can be seen in the line in the job ticket.

Between Jobticket and UGRA/Fogra media wedge, an additional media wedge can now be printed on which the contained spot colors – in this case the four PANTONE colors – are mapped. The measured results of the special color deviations can then be output in a separate test report.

How accurate can PANTONE colors be reproduced in proofing?

Pantone colors can be simulated very well today. T be able in advance to see how well your Pantone color can be reproduced, we have published tables of all Pantone inks where the color differences of the Pantone colors can be looked up already before proofing.

Color deviation of Pantone metallics and Pantone Premium Metallics color in proofing in Delta-E (∆E)

Current proofing systems can print spot colors like Pantone or HKS very accurate. With Fiery XF 5.2 Proof software and the Epson 7900/9900 proof printers we evaluated, with which color deviation PANTONE Metallics Coated and PANTONE Premium Metallics Coated colors can be reproduced in proofing.

The color deviations were calculated based on the measured color space of the proof system of Proof GmbH by the proofing software. Deviations should therefore be quite similar in practice. Almost all PANTONE colors can be simulated quite well in the wide color gamut of the proofer.

The smaller the Delta-E value, the lower is the color distance of the PANTONE reference to the proofed PANTONE color. Higher Delta-E values ​​show, which PANTONE Colors can’t be simulated accurately in the proof.

Please note: Since the proof devices does not have colors with metallic pigments, the metallic shine in the proof can not be reproduced. Only through the satin finish of our proofing paper a somewhat shiny effect is produced, which replaces partly the metallic luster of true PANTONE colors. Although the color is well rendered, the metallic effect in the proof does not exist. The proof can therefore always be used only as a guide, but not as binding simulation of the final result.

Pantone Color Chaos 2014: 84 new Pantone Plus color Pantone annoy users

Pantone has added a further 84 colors to ist Pantone Plus color palette in March 2014. The the total amount of the Pantone Plus color now extends to 1755 colors as Pantone writes on his website. The colors were – matching the Pantone color of the year: Radiant Orchid – expanded in the Rouge and Pink range, based on the previous base colors.

Two other changes compared to the previous 50th Anniversary PANTONE guides are visible:

  • The cover sheets have been redesigned
  • The order of color arrangement has now changed by going to chromatic criteria and now corresponds to the chromatically correct order. The colors from 2010 and 2012 have now been logically integrated into the new color fans.

For the CMYK guides and the Premium Metallics and Neons & pastel color guides only the cover pages have been updated. Graphic artists and the printing industry should forthwith upgrade its Solid Coated and Solid Uncoated guides to those of 2014 or newer.

Customers are annoyed by Pantone Product Policy

Since the year 2010, there has been chaos in the PANTONE Plus color portfolio, which is not improved by the new color guides generation. At present, there are four parallel Pantone Plus color guides on the market, three of them with different number of colors included in the guide, although that is hardly communicated by Pantone.

The same is true for the Pantone product partners such as Adobe: Hardly any graphic designer knows what Pantone Plus color are integrated into Adobe the specific Version since neither Pantone nor Adobe characterize their color guide generation different. Pantone’s statement: “Compatible with today’s digital workflows – colors can be easily updated in leading design applications” translates rather: “What Pantone colors you see in your application, is pure cuincidence – depending on the update status and your manual intervention.”
