Disclosed herein is a method for flexographically printing over a textured surface. The method comprises selecting a substrate for application of a print pattern and advancing the substrate through a flexographic coil paint line in order to apply a primer to at least one side of the substrate. Next a finish coat is flexographically applied to the primed substrate and due to a chemical reaction of the applied finish coat along with supplemental heating, the finish coat forms a textured surface. Next, a print pattern is flexographically applied atop the textured surface.

A method of printing an image on a substrate is described. Particularly, a coated covering adhered to a substrate may undergo plasma treatment to facilitate printing an image on the coated covering. Plasma treatment may be used to raise the surface energy of the coated covering to allow for printing an image on the coated covering.

A multi-optical-color optically-variable printing device having: a conveying unit; a screen printing unit, configured to printing an ink or a varnish containing a magnetic substance on a printing stock; and a plurality of optical-color optically-variable pattern forming units. Each optical-color optically-variable pattern forming unit comprises: magnetizing rollers, magnetic orientation components being arranged on each magnetizing roller and configured to performing magnetic orientation on the printing stock; and pre-drying and curing devices, configured to pre-drying and curing the printing stock, each pre-drying and curing device comprising optical mask curing devices, the optical mask curing device being fixedly arranged and configured to projecting dynamically refreshable variable optical field image-text, and the variable optical field image-text and the printing stock synchronously moving a predetermined distance.
