tec4check - About us

Print inspection and Quality check software

As a system partner for the printing and processing industry we develop software and systems to check the print quality against the approved PDF-File, so called print inspection or print verification systems. Therefore we ensures the quality of digital and printed products throughout all process steps. The systems ensure a maximum of printing quality by detecting errors and faults.

Our story

Our story

tec4check was founded in 2008 in Braunschweig, as a resumption of „Krauß Software“ wich went insolvent beforehand.

We focused on the development of print quality check software and redeveloped the old product Pharma Print Control into the new Media Check.

In 2011 the company headquarter moved to Marburg. Our support- and development office was located in Northeim.

Several updates and upgrades were developed and issued.

In 2017 our Northeim office moved to Marburg. The operations were focused here, as our partner Dr. Gerriet Backer left the company end of 2017.
