Food Compliance

High-Speed Performance through Regulatory Intelligence The Challenge Printing on food-contact materials like napkins requires strict adherence to the Swiss Ordinance (SR 817.023.21) and the German BfR guidelines. However, many “off-the-shelf” food-safe inks are technically limited; they often fail in single-pass systems because they lack the sophisticated additives needed for high printing speeds and long opening […]

Marking and Coding

Pushing the Limits of HP45 (TIJ) Technology The Challenge In industrial coding—printing batch numbers, expiration dates, and barcodes—reliability is the only metric that matters. Many systems based on HP45 (Thermal Inkjet) technology operate in harsh factory environments where the printheads are often mounted without any capping system (the mechanical seal that protects nozzles during idle […]
