UV curable jet inks are viable materials to meet some industrial printing requirements, especially on non-porous materials such as coated papers, plastics, and metals. The chemistry of these systems is well understood but has not been widely discussed in the context of jet ink printing architectures.This paper will discuss some of the challenges of using UV curable drop on demand inks, specifically free radical cured jet inks, and discuss some practical considerations for the printing system architecture.Discussions will include various curing protocols and their affect on final ink properties, image quality and UV lamp power requirements.
