Hot Melt Inks for Colored Ink Jet Images Abstract In the particular embodiments described in the specification, hot melt inks (110,120) for colored ink jet images are described which have relatively narrow melting ranges while at the same time inhibiting crys- tallinity upon quenching to reduce attenuation of transmitted light. In addition, the inks (110,120) intended for application to the same substrate have matched surface tensions at the temperature at which they are maintained above their melting point on the substrate to avoid mingling of different inks at their interfaces. Furthermore, the inks have an elongation of at least 3%, and preferably about 5-10%, so as to avoid delamination from a transparent substrate de- spite relatively low adhesive strength of the ink to the substrate.
