Abstract
A micro-lens enhanced element comprises a substrate bearing sequences of printed image elements, each sequence containing image elements from more than one image. A transparent spacer layer is coated over the interlaced image strips. Lenticular lenses are fashioned over each sequence of image elements by deposition of a transparent layer of low surface energy polydimethyl siloxane based material and ablation of the same to create strips of material abhesive to a polymeric lens forming material between consecutive sequences of printed image elements. During deposition of a liquid lens forming material, the liquid withdraws from the liquid abhesive low surface energy strips to form a meniscus, thereby providing lenticular lenses. The transparent low surface energy material comprises a near infrared dye with low absorption in the visible range of the spectrum to render the material both transparent and ablateable by infrared laser.
