Kraftliner, also known as craft paper or kraft paper, 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.
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

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
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

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
In this short image video we – the Proof GmbH – introduce us and our work. Find out who we are and what drives us. What do you think of our short film?
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
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 … read more
