OS QM Tool: Quality analysis made easy

The OS QM-Tool is a software solution with which all relevant quality features of digital images can be analysed and evaluated according to ISO standards and guidelines.

Using ISO 19264-1 compliant Universal Test Targets (UTT), the analysis software captures and evaluates all relevant parameters with just one scan. Thus, the QM tool can determine within a few seconds whether an image complies with the required standard or not. Integration with the OmniScan scanning software is possible via an optional direct interface.

In this way, quality control is automated in the production process and not afterwards in a process downstream of production.

Quality analysis can be carried out on a random basis, for example after 100 or 200 scans. With a new solution from Zeutschel, inline quality inspection is now also possible with every scan. This means that there is no longer a single scan that falls outside the defined standard.
