Abstract
Embodiments of the present invention feature apparatus and methods for manufacturing a personalized identification document including one or more dyes and/or pigments embedded in the substrate.
Claims22
A method of manufacturing a personalized identification document, the method comprising the steps of:
- providing a polymeric substrate for the identification document;
- carbonizing the polymeric substrate with a carbonization laser so as to generate non-removable blackened marks thereon;
- providing a plurality of panels or containers, each having a dye or a pigment therein;
- sequentially activating a green laser operating at substantially 532 nm or an ultraviolet laser operating at substantially 355 nm to transfer, to the substrate, a first dye or pigment from a first one of the panels or containers and then to transfer, to the substrate, a second dye or pigment from a second one of the panels or containers, the second dye or pigment in the second panel or container having a second color different from a first color of the first dye or pigment in the first panel or container;
- and
- thereafter, simultaneously heating all of the polymeric substrate to a glass-transition temperature of the polymeric substrate so as to cause the first and second dyes or pigments to diffuse into the substrate.

Apparatus for manufacturing a personalized identification document, the apparatus comprising:
- means for supporting a polymeric substrate for the identification document;
- a laser for carbonizing the polymeric substrate so as to generate a non-removable layer having a black color thereon;
- means for supporting a plurality of panels or containers, each having dye or a pigment therein;
- a green laser operating at substantially 532 nm or an ultraviolet laser operating at substantially 355 nm for transferring, to the substrate, a first dye or pigment from a first one of the panels or containers and thereafter a second dye or pigment from a second one of the panels or containers, the dye or pigment in the second panel or container having a second color different from a first color of the dye or pigment in the first panel or container;
- and
- means for simultaneously heating all of the polymeric substrate to a glass-transition temperature of the polymeric substrate so as to cause the first and second dyes or pigments to diffuse into the substrate, the heating means being different from the carbonizing laser, the green laser, and the ultraviolet laser.
