Abstract
The present invention provides a method of producing a product comprising an array of product features () arranged on a surface () of a substrate sheet (), and an arrangement for the production of such products. In this method curable compound () is filled into recesses of a matrix (), pre-cured and then printed onto the substrate sheet (), thereby forming printed product features (). These printed product features () and additional product features () arranged on the opposed side of the substrate sheet () may form image objects and focusing elements, respectively, of a synthetic image device. By way of example a cast cure step can be used to form the additional product features (). Preferably the production of the product is performed in a continuous roll-to-roll process.
