A toner (102) for printing documents that are difficult to forge and that are readily easy to visually verify and methods of using and forming the toner (102) are disclosed. The toner (102) includes a colorant for printing an image on a surface (106) of a document and a dye (110) for forming a latent version of the image underneath a surface (106) of a substrate (104).
