Clear inks are prone to heat-induced micro-gelling that can cause their storage stability to drop, and micro-gelling may also occur in clear inks with the passage of time, in which case their inkjet discharge property may drop. As a solution, a photocurable clear ink composition for inkjet printing is provided, which contains a photopolymerizable compound, a photopolymerization initiator, and an inorganic filler of 1 to 200 nm in average grain size accounting for 0.05 to 5.0 percent by mass in the composition, and whose visible light transmission factor is 30% or higher.

The disclosure relates to systems and methods for photonic sintering of conductive ink compositions with metal nanoparticles. Specifically, the disclosure relates to methods and systems for sintering ink compositions with metal nanoparticles using an illumination source comprising an array of pulsed light emitting diodes (LEDs).
