Abstract

In order to achieve deposit of very complex embossed designs which require thick layers of inks or paints in sharply defined patterns on flexible sheet substrate material suitable for packaging and high-volume production, a new combination of production sheet-fed printing elements is disclosed. As the typical materials will be sheet material supplied on rollers, a continuous process of moving the material from a supply roller to a take-up roller through a series of application and curing steps is provided, including elements for the steps of thick-deposit of design print material, embossing or impressing the deposited material, curing the material and sealing or covering the print material, and taking up the imprinted material for further shaping or processing. Since any number of complex design features, such as multiple colors, differing embossed patterns, and varying thicknesses of design may all be combined in one overall design, the various parts of the design may require sequential application, and the continuous process may therefore embody two or more repetitive stations to apply different aspects of the design. Thus a continuous sequential printing process is provided with separate stations adapted to application of the varying parts of complex designs and the distinct layered construction required for deposit, fixation and stabilization of the imprinted designs.
