Patterns and preparation method with security optically variable structure

The present invention discloses a method for preparing a security Designs and having light redirecting structure, the security Patterns having light redirecting structure comprising printing on a support of lithographic printing lines and blind embossing intaglio embossed lines; lithography a set of lines is offset curve line with the curvature, the width of a lithographic line curve coarse to fine coarse or fine; blind embossing intaglio relief and lithographic printing line is a line corresponding to a group of lines having the same curvature of the curve, overprint in the above lithographic printing line, the same variation width of the relief line lithographic printing line; the line width of the present invention by accurately overprinting two kinds of printing method, the resulting relief structure continuously varying curve. Occurs when prints rotated continuously optically variable effects observed with an intuitive, easy to identify, copy-, difficult to forge. The dynamic light change security Designs and fabrication method can be applied to securities security.
