A method of applying an authentication image to an article is presented. The method comprises obtaining a digitized version of the authentication image, encoding the digitized version of the authentication image to produce an encoded latent image, and printing the encoded latent image on a printable surface of the article containing a primary image using a transmittent printing medium.
