Kraft paper, also known as craft paper, kraftliner or craftliner, is a particularly strong paper that plays an important role in the printing and packaging industry. The name ‘Kraft’ comes from the German word for ‘strength’, which describes the main property of this material well. It is mainly made from wood fibres, which are prepared in a special process known as the Kraft process. In this process, the wood chips are chemically treated to separate the cellulose fibres from the lignin. The result is long, resistant fibres that give the paper its strength.
This paper has a natural brown colour, but can also be bleached or dyed in different colours. It is very tear-resistant and resistant to mechanical stress, which makes it ideal for packaging heavy or bulky goods. It is often found as the outer layer of corrugated cardboard used for transporting goods.
Another common application for kraft paper is carrier bags and envelopes. Carrier bags made from kraft paper are very popular in the retail sector as they are strong enough to transport purchases home safely. These bags are often printed to display a shop’s logo or advertising message. Kraft paper envelopes are also useful, especially when it comes to sending documents and smaller items securely.
Kraft paper can also be found in labels and tags, especially in the fashion and food industries. They give products a rustic and natural look. Kraft paper is also popular in the printing sector, especially for printed matter that is intended to convey an environmentally friendly or handmade impression. Although the print quality on the rough surface is not as good as on smoother papers, the natural look has its own charm.
A major advantage of kraft paper is its environmental friendliness. It is fully recyclable and biodegradable. Many manufacturers make sure that the wood used comes from sustainably managed forests, and unbleached kraft paper also saves on chemicals, which further reduces the ecological footprint.
To summarise, kraft paper is a strong, versatile and environmentally friendly material that is used in many areas of the printing and packaging industry. It offers practical benefits and aesthetic qualities that make it a popular choice for businesses and consumers who value sustainability.

MYIRO-9: New Spectrophotometer from KonicaMinolta in action
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 … read more
Incorrect grayscale display in Adobe Photoshop and InDesign
Adobe products are ideal for image retouching and layout and handle RGB and CMYK colour profiles very well. However, when editing and retouching grayscale images, for example for a black-and-white photo book, the experience is quite different. Suddenly, images look completely different in InDesign than they do in Photoshop, and even when exporting the image to PDF, greyscale images are suddenly treated differently. This article explains where the problems lie with black-and-white images and greyscale profiles in InDesign and Photoshop layouts, and how you can work in a more ‘colour-accurate’ … read more
Precise proofing of tonal values of spot colours
In recent weeks, there have been lengthy discussions on the Fogra digital printing mailing list as to whether a research project should be launched to define standardised tonal value gradations for spot colours. What is this all about? In the field of CMYK and seven-colour printing, the definition of clear, printable and proofable standards is well established and has been tried and tested in practice. If the paper or paper class is known and defined, a measuring standard such as M0/M1/M2 has been established and the content of optical brighteners … read more
Proof.de is featured twice in the “Fogra Aktuell” magazine
In the current issue of Fogra News “Fogra Aktuell” Proof GmbH is involved in two places. Firstly, a summary of the Fogra report on our first FOGRA55 certification for seven-colour printing with extended colour space in CMYKOGV appeared. You can also find more information on our FOGRA55 certification on the Fogra website: https://fogra.org/en/press-releases/fogracert-erste-cpc-zertifizierung-fuer-fogra55-cmykogv-330 and on proofing.de: And secondly, there was a report on the completion of the research project for textile digital printing, FOGRA58, in which we were allowed to investigate and test the proof capability of the new textile … read more
Colour deviations in 2023 PANTONE Color Bridge Guides
After Eddy Hagen pointed out in this posts, that there were some major colour deviations between the brand new PANTONE Solid Coated Guide 2023 and the previous version especially for the PANTONE 2635 C, I was curious to lookup the same colours in the new PANTONE Color Bridge Coated Guide of 2023 and compare the colours with the previous version. I measured a dE00 of 8,15 between the two colours that Eddy mentioned, which is really far apart from how accurate PANTONE colours should match between the different PANTONE guides. … read more
New PANTONE Formula Guides with incorrect ink formulations
Several errors have crept into the new PANTONE 2023 fan decks. In both the PANTONE Solid Coated and the Solid Uncoated color fans, there are colours for which the new ink formulations are incorrect. In the PANTONE Formula Guide Solid Coated fan 2023, PANTONE 107 C and PANTONE 108 C have absolutely identical ink recipes, as well as PANTONE 113 C and PANTONE 114 C. As the colors differ, this cannot be the correct. Several errors in the PANTONE Solid Uncoated fan 2023 In the PANTONE Solid Uncoated fan 2023 … read more
New certified proof papers at proof.de
In recent years, various problems have arisen with our previous proof paper supplier. On the one hand, we sometimes had to wait more than three months for paper deliveries; on the other hand, we sometimes had significant problems with batch-to-batch discrepancies, surface defects and much more. After lengthy deliberations, we decided in December to replace all the paper. We therefore received pallets of new paper at the turn of the year, which we are now gradually incorporating into our production. There will be no hard cut, but the new papers … read more
New iPhone colour measuring devices: xade nano+ in test
A new generation of colour measuring devices is entering the market: in contrast to the classic measuring devices, which are available as a fully encapsulated system either as a colourimeter or as a spectrophotometer, and then supply the data to a computer via an interface or app or display it directly, the new generation of colour measuring devices consist only of lighting and software, with the optics of a modern iPhone from Apple being used as the sensor. Until now, there have been two categories of measuring devices on the … read more
Proofs with Digimarc EAN codes and verification
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 … read more
Proof GmbH 2025 once again Fogra and Fogra “Spot Cert” certified
This year we once again created proofs for Fogra certification and sent them to Munich-Aschheim for testing. With these proof prints, which we print according to three different proof standards and on three different papers, we point out that we not only deliver excellent proof quality through internal quality controls and checks, but that the quality of our proofs is also measured and confirmed by external experts. We have now had test prints certified by Fogra for the 12th time. We have also been “Spot-cert” certified for the display of … read more
