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.

Even almost 9 years after the introduction of the successor colour space PSOCoatedV3, ISOCoatedV2 / FOGRA39 is still the most widespread colour space in Europe. We at Proof GmbH count around 200 jobs from time to time for the German Printing and Media Industries Federation, among others. In the last count, proofs in ISOCoatedV2 accounted for around 68% of all proof jobs at our company. This is a clear sign of the continued widespread use of the colour space. ISOCoatedV2: From the classic colour space to the beacon of the … read more

In 2021 proof.de was again Fogra certified including Fogra “Spot cert” certification, i.e. for the display of spot colours such as PANTONE C and U.
Today I received an email in which PANTONE asked how it should orientate its products and services in the future. The users were asked which countries, industries and company sizes they come from, but also what PANTONE products should look like in the future and what customers would be prepared to pay for PANTONE services in the future. Question: How much can PANTONE services cost? PANTONE appears to be orientating itself on the PANTONE Connect prices: All price queries have the lowest price category < $ 7,- / month, i.e. … 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
Whether it’s a large global corporation or a small company, the following often applies to designs or redesigns today: we develop everything for digital first.
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
Peter Jäger is an expert in colour management that reliably works across the boundaries of printers and monitors, web and print – essentially: cross-media.
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
