Inks consisting of two and three pigments as well as an infrared absorber were printed onto plain paper and treated using a Q-switched Nd:yttrium–aluminum–garnet laser. It has been shown that the color of these inks can be altered through selective pigment decay: a red, green and blue ink decayed red first, then green, leaving a blue mark or a purple one, selectively. The process is related to the thermal decomposition temperature of the pigments used which is dependent upon the incident laser intensity. © 2003 Laser Institute of America.
