Our corporate values of mindfulness, agility and sustainability are reflected in the following certificates.
With these, we document our continuous quality assurance as well as the conscious use of natural resources.


High product quality requires systematic quality management.

DIN EN ISO 9001 is a globally recognized standard that defines requirements for effective quality management in a company. Our customers can rely on us to make a decisive contribution to the safeguarding and continuous optimization of our products and service offerings through the certification and implementation of ISO 9001, which has an impact on performance, speed and cost-effectiveness.

For our employees, this means binding and transparent documentation and regulation of responsibilities, competencies, structures and workflows. The procedural instructions as well as the continuous improvement process ensure that quality orientation is lived by each of our employees day after day.

Sustainability header


The Forest Stewardship Council (FSC) is an international, independent, non-profit organization based in Germany. Its goal is to promote ecological, social and economic management of forests around the world.

The FSC certificate identifies forestry operations or products made from wood - such as paper and cardboard. The processed wood must come from forests that are managed in compliance with strict guidelines.

The FSC basic principles include, among other things, the compliance with national laws as well as international agreements and the preservation or improvement of the social & economic situation of all employees in the forestry operation. Furthermore, the following aspects are taken into account: Respect and protection of property and rights of use for cultivated land and forest stands, as well as the long-term preservation of social and ecological services of the forests.

The PEFC seal guarantees that wood and paper products come from sustainably managed forests. Currently, more than 265 million hectares of forests worldwide are managed according to PEFC standards.

Forest certification according to PEFC standards is subject to very strict guidelines. In addition to sustainable forest management, ecological, economic and social criteria are equally taken into account.

Compliance is verified by competent and independent organizations, so that retailers, processors and consumers can be sure that the entire product manufacturing process - from raw material to ready-to-use end product - is controlled and certified.

Certified for further processing

Our materials are characterized by high quality to create the best possible conditions for further processing.

Many of our products have been tested and recommended as ideal materials by partners such as Canon, Zünd, Esko, Eurolaser and HP.

HP, for example, has certified our KROMA® Displayboard and KROMA® Kraft among others, for printing with HP Latex Inks and recommended us in HP Media Locator. For this, both materials for the HP Latex R printer series were tested by Color Concepts, an independent testing laboratory for the professional digital wide-format printing industry. The test program checks for proper machine settings and includes various parameters such as optical print quality testing, ink adhesion and scratch resistance. Thus, this procedure ensures that the materials meet the highest standards.
