A visual security feature is provided that is disposed on a target. The visual security feature includes two substantially transparent layers. At least one of the two substantially transparent layers is present in an image-wise pattern.

Apparatuses and methods for printed security features

A method is provided for printing to a target. The method includes printing a first image to the target. The first image is printed with a metallic material. The method also includes printing a second image to the target over the first image. The second image is printed with a colored semi-transparent material.

Apparatuses and methods for optically variable printing

A method for enabling D2T2 printing onto non-D2T2 printable substrates uses a diffusible primer material provided on a dye-sheet or ribbon. The primer comprises a polymer, a release agent and a plasticizer. The release agent and the plasticizer are diffused into the substrate, while the polymer remains on the dye-sheet or ribbon. Printing of the primer onto the PC substrate is controlled via a computer image program corresponding to a colored image. This computer image program also controls the printing of the colored image at the primed locations. Accordingly, image-wise treatment of a plastic material via the primer selectively renders the PC substrate surface D2T2 printable at the point of personalization, providing for a 100% PC full card body having the colored image.
