Embodiment Construction

[0019] Throughout the drawings, the same reference numerals are used for similar or corresponding elements.

[0020] A product manufactured according to the present teaching comprises a body constituting, either in the product, or in an intermediate product, a substrate sheet having a finite thickness with respect to its extension in an orthogonal direction thereof. The product has printed product microfeatures disposed on or in one or both major surfaces of the substrate sheet. As an example, one embodiment of the product may include primary product microfeatures on a first side of a base sheet and secondary product microfeatures on an opposite side of the base sheet. Primary product microfeatures are usually positionally related to secondary product microfeatures. Other embodiments of the product may include three or more sets of product microfeatures. In its most basic form, the product comprises a substrate sheet with product microfeatures printed on only one of its surf...

Abstract

A method for manufacturing a printed product comprises provision (210) of a matrix comprising a matrix surface having a plurality of recesses. A first curable compound is applied (212) to the matrix surface to fill the recesses with the compound. The matrix surface and the filled recesses are covered (220) by a pickup layer of a second curable compound. The matrix is brought (230) in contact with the substrate surface and the first curable compound and the second curable compound are cured (232). The matrix surface is separated (234) from the substrate surface, leaving the pickup layer and the first curable compound on the substrate surface. The pickup layer and the first curable compound are thus transferred (240) together from the matrix surface onto a substrate surface of a substrate sheet. The first curable compound forms printed product micro features at the pickup layer covering the substrate surface.

Description

technical field [0001] The present invention relates generally to the manufacture of printed products, and in particular to methods and arrangements for producing printed products having printed product microfeatures disposed on the surface of a substrate sheet. Background technique [0002] Optical arrangements that produce composite three-dimensional images or images that change their appearance at different angles have been used in many applications. Apart from purely aesthetic uses, such arrangements have been used, for example, as security markings on banknotes or other documents of value, identification documents etc. or as brand protection. Synthetic three-dimensional images have also been used to provide a better geometric understanding of complex shapes, eg in two-dimensional information files. [0003] The composite image device is based on the interaction between an array of focusing elements and a microimage portion. In some prior art, a "synthetic image" is al...
