Problems solved by technology

Too high a printing speed generally deteriorates the wiping efficiency and thus the quality of the final product
[0009] In other words, in prior art manufacturing methods, there may be problems with ink scatter and wear when they are used for high speed manufacturing

Embodiment Construction

[0021] Throughout the drawings, the same reference numerals are used for similar or corresponding elements.

[0022] 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 base 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 surfaces....

Abstract

A method of making a printed product comprising providing a substrate including a substrate surface having at least one recess. The first curable compound is coated on the surface of the substrate, and the coating amount is controlled so as not to exceed the volume of the recess. The first curable compound creeps down into and partially fills these recesses, leaving the protruding surfaces substantially free of the first curable compound. The substrate surface and filled recesses are covered with a pick-up layer of a second curable compound. The matrix is ​​brought into contact with the substrate surface, and the first curable compound and the second curable compound are cured. The substrate surface is separated from the substrate surface to leave the pick-up layer and the first curable compound on the substrate surface. The first curable compound forms print product microfeatures at the pick-up layer overlying the surface of the substrate.

Description

technical field [0001] The present invention relates generally to the manufacture of printed products, and in particular to methods and apparatus for producing printed products having printed product microfeatures disposed on the surface of a substrate sheet. Background technique [0002] Optical devices 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 devices 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 also referred t...
