Offset printing

The research projects are directly related to printing practice. In most cases, a connection is established between the print quality, the process parameters and the materials used. The results also contribute to the further development of national and international standardisation.

Focus areas

Print quality

The term print quality does not only refer to optical properties such as colour, gloss, detail reproduction, print evenness or image register. It also includes ink adhesion or other strength properties of the printed product.

Print production and process parameters

In order to ensure economical and high-quality print production, sophisticated adjustment and control of the printing machine is required. Furthermore, the parameters stipulated in the standardization concept, solid tone colour and tone value increases, as well as ink acceptance in multicolour overprinting, must be adhered to.

Material influences

The interaction of the materials substrate, ink, dampening solution, blanket and printing plate is crucial for achieving a satisfactory print quality. They also have a major influence on solid tone colour and tone value increases as well as the stability of the printing process.

Our research projects are characterised by a high level of practical relevance. Therefore, I always have an open ear for problems that go beyond a simple expert opinion. Perhaps a future Fogra research project will develop from this!
