Offset film lamination with matt or glossy OPP film of a print according to Fogra51 PSO Coated V3

Publication of Fogra 56/57 for Glossy and Matte Film Lamination of PSOCoatedV3 Prints

by

A few days ago Fogra published the characterisation data for the new printing standards Fogra56 and Fogra57 while ECI provided the respective ICC profiles for download on the eci.org website. FOGRA56 and FOGRA57 are the separation and printing standards for matte and glossy film lamination of “PSO Coated v3” / Fogra51 prints. At Proof.de, with regard to the two predecessor standards Fogra49 and Fogra50 for glossy and matte film lamination of ISOCoatedV2 / Fogra39 prints, the majority of inquiries were for the standard for matte film lamination only, as this …

DeviceLink PDF Colour Conversion

DeviceLink PDF Colour Conversions for Ads

by

We have recently started offering DeviceLink colour conversions via DeviceLinks made by ColorLogic from numerous RGB and CMYK standards into other CMYK standards from offset and gravure printing.

DeviceLink PDF Colour Conversion

Optimised colour conversion between different printing standards

The colour conversion profiles preserve the separation structure, limit the total colour application for the selected printing standard and maintain the purity of the primary and secondary colours. They ensure smooth transitions in gradients and enable correct conversion of PDF and PDF/X data. Separation-preserving conversion ensures that pure grey tones are not built up into four colours and that duplex tones (black+primary colour) and triplex tones (black+secondary colour) remain pure, while still being colour-metrically transformed in the best possible way. In addition, the colour impression of the source colour space is optimally preserved in the target colour space by taking into account both paper colouration and dot gain.

Limitation of Total Allocation of Colour (TAC)

For current printing standards of ISO, Fogra, ECI, Ifra, Gravure (PSR), Gracol, Swop, SNAP, these profiles ensure a targeted limitation of the maximum ink application without completely new separation. This reliably prevents problems with set-off and improves the drying behaviour. These profiles are suitable if the data is generally already in the desired colour space, but individual images or objects have too much ink application.

proof.de Packaging of a Proof/ Digital proof

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.

But what makes the certified proof cheap? That’s the low price. Proofs are printed on certified proof papers on very high-quality pigment inkjet printers, usually using expensive proofing software, and measured with spectrophotometers. So how can production be done cheaply here?

1: Using cheap pigment ink?

One litre of ink for proofing devices is around 400 EUR, so it makes sense to use inexpensive alternative ink from China. The problem: there are no manufacturers – neither in China nor anywhere else – who produce inks that would actually produce similar inks in terms of pigment colour and spectral composition. I once called a manufacturer who advertises that his – already quite expensive – inks could also be used for proofing. When I asked him, he said: “No, no, that’s just for advertising, but of course I would never do that or recommend it, and I don’t know anybody who does that. As for the China inks, he said: “They start at 20 EUR per liter, but you get a different ink with every delivery, depending on where the wholesaler buys. Then they have to re-measure the proofer every time… forget it.” In addition, replacing a clogged print head costs around 2,500 EUR, so the risk is too high. A real proof therefore only works with original, very expensive ink.

2: Using cheap software?

GMG ColorProof, EFI Fiery XF and ORIS Color Tuner are just some of the most important proofing solutions on the market. What they all have in common is that proofing software is rather a niche software, so the programming effort is very high compared to the sales figures. Depending on the size of the output device and the range of functions in terms of verification, spot colour display or proofing on special materials such as transparent foils, etc., the software costs between 5,000 and 10,000 EUR, and in combination with other software products from GMG or Colorlogic it can quickly cost considerably more. Although there are a few low-cost solutions here too, these are usually irrelevant in professional proofing, as they are either not suitable for more than one workstation, or important functions such as spot colour libraries etc. are missing.

EPSON SureColor P9500 spectro

Epson has incorporated many improvements into the new printer generation. For example, fully loaded print heads now work in the new printers, which can finally handle photo black, matt black and the two grey tones LightGray and LightLightGray as well as the colours orange, green and violet simultaneously in one print head. For cyan and magenta there are also the light variants light-cyan and light-magenta, so that besides yellow, cyan and magenta, 12 full colours are available in the print head. The printer uses the new UltraChrome Pro12 ink set, which could possibly bring some detail improvements to the classic K3 inks, although nothing more is known about this yet.

Good times: The general meeting 2019 of freieFarbe e.V. in Switzerland

by

After the association freieFarbe e.V. had met last year in Tübingen for their annual general meeting, this year we met in a rustic hut in the Appenzeller Land, which Peter Jäger from pre2media and Eric A. Soder from pixsource.com had excellently chosen, just like the sunny weather that should accompany us from Friday to Sunday.

freieFarbe e.V. general meeting 2019: Our accommodation in the Swiss mountains

The chairman of the association, Holger Everding from DTP Studio Oldenburg and Jan-Peter Homann from Homann Colormanagement in Berlin arrived in Tübingen on Thursday, and after a first long night full of discussions and a meeting in the Proof.de office on Friday morning around noon, the three of us continued our journey to Switzerland. After a joint dinner with Peter Jäger and Eric A. Soder (from Tübingen, we had taken some Swabian potato salad and my handmade Maultaschen with us the evening before), an evening full of planning and a strategy workshop for the tasks and goals of the next year began. Without question, this evening was also spent discussing, developing, laughing and working creatively until late into the night between Flensburger Pils, Swiss mountain beer and wine in attractive red and light yellow shades.

How to match the production paper, proof standard and the proof precision of spot colours

by

Today a customer called who wanted to order a proof of several HKS N spot colours on an uncoated paper. “Which proof profile should I choose? And how exactly can you match my special colours in the proof? I probably have to proof several HKS N red tones in comparison. By the way, the printing is to be done on Fly Cream, a slightly yellowish paper.”

What is the paper white of the production paper?

First of all, I searched with the customer for the production paper in our paper white database. A quick look via full text search revealed that we have measured Fly Cream from Papier Union:

Fly Cream enthält gemäß unseren Messungen keine optischen Aufheller, also "keine OBA". Das LAB Papierweiss liegt bei allen drei Messungen bei rund LAB 95 / 0,7 / 9,2
According to our measurements, Fly Cream does not contain any optical brighteners, i.e. “faint”. The LAB paper white in all three measurements is around LAB 95 / 0.7 / 9.2

With a B-value in LAB of 9.2, Fly Cream is really not just a little yellowish, as the customer said, but clearly yellowish, chamois, creamy … whatever you want to call it. So it was natural to check the proof profile “ISOUncoatedYellowish”, Fogra 30, to see to what extent the paper white could match.

What is the paper white of the possible proof standard?

Together with the customer we looked up our “paper white of proof profiles” table:

Das Papierweiss des Proofstandards Fogra30, ISOUncoatedYellowish
The paper white of the proof standard Fogra30, ISOUncoatedYellowish in LAB: 95.93 / -0.77 / 3.85

Contrary to the customer’s expectations, the paper white of ISOUncoatedYellowish is not even as yellowish as the paper white of the edition paper Fly cream, which is more yellowish by more than 5 steps on the B axis. So it was clear: PSOUncoated as a brighter-free uncoated paper proof standard is clearly too white, ISOUncoatedYellowish is much more suitable.

On what kind of proof paper will this proof standard be printed?

eciCMYK profile available for proofing

by

Today we have activated the exchange colour space eciCMYK, Fogra53 for proofing and integrated it into the online shop of proofing.de for ordering. eciCMYK is the colour space for CMYK print production and complements the other Fogra colour spaces, but in contrast to these it does not represent a specific printing process, but is rather “neutral CMYK”. Due to the large gamut of eciCMYK all classical printing processes can be represented, it can be proofed on modern proofing systems without any problems and corresponds in its characteristics to typical CMYK …
