09557675 · 2017-01-31 · ·

Fluorescing highlights can be provided in selected portions of non-color image areas of a printed toner image using fused fluorescing dry toner particles, such as fused fluorescing magenta or fused fluorescing yellow dry toner particles. Before fixing, each fluorescing dry toner particle comprises a polymeric binder phase and a fluorescing colorant that emits at one or more .sub.max wavelengths of at least 420 nm and up to and including 690 nm and that is dispersed within the polymeric binder phase. The resulting printed color images and fluorescent highlights can be provided on receiver materials of various types to accentuate or emphasize the printed color images with a variety of light-colored fluorescent shading.

Digitally printed labels

Described are primer coatings, overprint varnishes, and seaming solution solutions for application to substrates such as those used to make wrap around and sleeve labels, particularly shrink wrap labels, which are used to label containers. The labels can be digitally printed with or without lane priming. With certain seaming solutions, the labels can be removed in the wash stage to enable the recycling of containers.
