Intense pulsed light (IPL) annealing of graphene inks is demonstrated for rapid post‐processing of inkjet‐printed patterns on various substrates. A conductivity of ≈25 000 S m −1 is achieved following a single printing pass using a concentrated ink containing 20 mg mL −1 graphene, establishing this strategy as a practical and effective approach for the versatile and high‐performance integration of graphene in printed and flexible electronics.
