UV-curable inkjet printing is a new technology that is expected to grow significantly in the next few years. The extremely low ink viscosities required for this application entail extensive modification of the conventional formulation equilibrium between oligomers, monomers, and photoinitiators. The impact in terms of curing efficiency then has to be balanced by modifying combinations of photoinitiators in this new binder environment. Pigment selection will be driven by more demanding requirements in terms of resistance to flocculation and gelling. This paper describes the influence of optimized additive and pigment selection on UV inkjet inks.
