Proof Software and Technology

Here it’s all about the software side of proofing. EFI, Fiery and GMG Color and much more to come here as a theme for discussion.

Proofs with Digimarc EAN codes and verification

by

Digimarc is a digital watermark that can be used to embed information in images, videos or other media. Digimarc watermarks are invisible to the human eye, but remain recognisable to special software or devices. Digimarc is becoming increasingly popular in the packaging sector in particular, as this technology allows the digits of the EAN barcode and more to be applied invisibly to all areas of the packaging. Digimarc and EAN barcode at the supermarket checkout When scanning at the checkout, the checkout staff do not have to search for the …

MYIRO-9: New measuring device from KonicaMinolta in use at Proof.de

MYIRO-9: New Spectrophotometer from KonicaMinolta in action

by

Over the last few months, we at Proof.de have been thinking about further improving our already very good colour measurement technology in terms of speed and measurement precision. Relatively quickly it became clear that only two devices would come into question: The KonicaMinolta MYIRO-9, the successor of the former FD-9, or the X-Rite ISIS 2 XL.  The starting point: Since we at Proof GmbH have 5 proofing devices, the calibration of targets for profile optimisation is a time-critical undertaking for us. Therefore, we had been looking around for an upgrade of …

Proof GmbH Tübingen Fogra Certification FOGRA55 7C Matthias Betz examines 7C test form

We passed the first proof certification for the 7C proof under FOGRA55

by

A few days ago Proof GmbH was the first company to be certified for proofing for the new 7C exchange colour space FOGRA55. Fogra has developed characterisation data for extended multicolour printing with the printing colours CMYKOGV – i.e. cyan, magenta, yellow, black (contrast), orange, green and violet – FOGRA55 as part of a research project over the past few years. The characterisation data and the ICC profile Ref-ECG-CMYKOGV_FOGRA55_TAC300.icc have been published on the Fogra website in recent weeks. We have now carried out the certification via GMG ColorProof, as …

Proof cheap. What does that mean?

by

Proof cheap is a typical search term that people use in search engines to find a cheap, colour and legally binding proof. But what makes a cheap proof?

A proof is one that is produced according to the specifications of the latest revision of the proofing standard ISO 12467-7 and is within the tolerances of this standard. The current revision is ISO 12647-7:2016, which has been tightened even further with this standard and has been supplemented by a certified edition of spot colours such as PANTONE and HKS.

Such certified proofs can be ordered at shop.proof.de for all proof profiles.

First online printers switch to PSOCoatedV3 and PSOUncoatedV3

by

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 …

Two years after publication: Large printing companies switch to Fogra 51 and 52

by

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 …

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

by

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.

Comparison of PANTONE U colours to Contract Proof

Colour deviations from PANTONE EXTENDED GAMUT Coated in the proof in Delta-E (∆E)

by

Current proofing systems can reproduce spot colours like HKS or Pantone very well. Using the Fiery XF 6.3 proofing software and the Epson SC-P9000V proof printer, we evaluated with which colour deviation in Delta-E the PANTONE Extended Gamut Coated colours can be proofed.

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.

Scheufelen Heaven 42 Heaven42 Comparison with digital proof from Proof GmbH

Heaven 42 proofs on proof paper with optical brighteners

by

The Proof GmbH provides proofs for Scheufelen Heaven 42 papers on the new EFI 8245 OBA proofing paper. With this new proofing paper it is now possible to proof the bright-white paper dye of Heaven42l. With Heaven 42 a bright white paper was developed by the German paper company Scheufelen, which opened up a new color whiteness. Especially technical motifs (shades of gray, silver tones from 4c, strong contrasts) act on Heaven 42 particularly brilliant and neutral. With an unchanged separation (eg with ICC profile “ISOcoated_v2”), but the printed image with the …
