Printing ink set-off testing with ethanol solution; analysis with GC-MS

Printing ink set-off can occur on the reverse side of printed labels, lids, cups, and packaging film, either in a stack or in the reel after printing. This creates a potential for low-molecular-weight substances to transfer to the unprinted surface of the packaging that makes contact with the packed contents.

The price includes a simple risk assessment based on the Swiss Ordinance for printing inks (SR 817.023.21), EU regulations for food contact materials, and EFSA's Threshold of Toxicological Concern (TTC) approach. More extensive risk assessment is available upon request.
