Besides intentionally added substances (IAS) printing inks may also contain small amounts of substances, which are non-intentionally added (NIAS) and which may also not be listed in any official substance list approved to formulate food-packaging printing inks.
This document provides guidance for the risk assessment of non-intentionally added substances (NIAS) and non-listed substances (NLS) migrating from printing inks used for food contact materials.

In addition, it points out the reasons why an independent rigorous risk assessment must be carried out by the converter to ensure safety-in-use of the printed packaging.
