Topic of your interest

Everything the offset heart desires!

We deal with topics related to the offset printing process, whether sheet-fed or web offset, including heatset and coldset. Material influences are taken into account as well as measures for process reliability.

Research

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.

Research

[Translate to EN:]

Mackle and CO2 savings through paper-dependent pre-adjustment of sheet-fed offset presses

Offset printing   09/01/2020

The aim is to establish a new paper characteristic value that allows to predict the expected solid tone densities and tone value increases.

Laboratory method for the practical and reproducible determination of the residual strength of papers for heatset web offset printing

Offset printing   03/31/2020

Within the scope of the research project, an already existing laboratory method for testing the residual strength is to be further developed.

Integration of the highspeed inkjet into conventional offset production environments

Offset printing   10/31/2019

Typical offset print products are to be identified and provided with quality requirements that are customary in practice.

Communication of characteristic values describing the metallic appearance of prints

Offset printing   11/01/2018

Objective parameters are to be established that correlate with the visual impression of printed metal surfaces.

Modelling the printing behaviour in sheet-fed offset printing on the basis of measurable paper properties

Offset printing   04/30/2018

The paper-side factors influencing solid tone colouring and tone value increases in sheet-fed offset are to be determined.

Reduction of "Picture Framing" in sheet-fed offset printing through targeted selection of material and application parameters

Offset printing   03/31/2018

Within the framework of the research project, a better understanding of the development mechanisms of "Picture Framing" is to be achieved.

Testing

Our clients are print shops and print buyers as well as manufacturers of printing machines, inks and papers.

A typical concern is the assessment and troubleshooting of complaints regarding print quality or the used materials. However, there is also a frequent demand for investigations that are intended to serve the further development of products.

In order to assess how we can help our customers, we recommend to first send us some samples for a non-binding and rough examination.

Our core competence lies in the evaluation of print results and error analysis. This includes technical and colourimetric evaluations of printed copies. Furthermore, we offer testing accessories and material examinations which are directly related to the printing process.

Testing

Certification

The ProcessStandard Offset (PSO) and the ISO 12647 series of standards are considered to be indispensable tools for colour reliable print production. The use of printing inks in accordance with ISO 2846 is a prerequisite for achieving the target values specified therein. Fogra also certifies the consumables and additives required for the printing process, e.g. fountain concentrates and washing agents.
