Abstract

The color of organic pigments for commercial printing applications, commonly considered as invariable, can be “tweaked” by adjusting chemical environments surrounding the pigment particles. The extend of color change, though small, is frequently noticeable with a naked eye. This phenomenon is due to subtle interactions between the surface molecules of the pigment and surrounding polar moieties either chemisorbed or vicinal to the pigment surface. Detailed understanding of this effect may allow avoiding undesirable color changes degrading the printed color quality. It may also be used in development of advanced inks for various printing applications.
