Since the food scare that developed from the discovery of the photo-initiator ITX (2-isopropylthioxanthone) in infant formula, there has been a focus on migration of chemicals from printing inks, particularly photo-initiators and their decomposition products. This e-book examines the technology issues with regard to compliance with both the GMP Regulation (EC) No 2023/2006 and the Framework Regulation (EC) No 1935/2004.
