Abstract:
A method of forming a lenticle on a substrate includes operating a plurality of inkjets to eject a plurality of ink drops of an optically transparent ink onto a surface of a substrate between a first printed line of an optically opaque ink and a second printed line of the optically opaque ink to form a lenticle from the optically transparent ink, the first printed line being formed substantially parallel to the second printed line with a separation between the first printed line and the second printed line corresponding to a predetermined width of a lenticle to be formed on the substrate.
