A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes ethyl cellulose as a binder. The dye-donor element is capable of printing a defect-free image on a receiver element at a line speed of 2.0 msec/line or less while maintaining a print density of at least 2.0.

Thermal donor for high-speed printing

Thermal printers and methods for operating a thermal printer that applies donor material from donor patches on a donor ribbon to a received medium, the donor material being organized into sets, each set including at least one colored donor material patch and a protective material donor patch. A non-visible light is applied to a location on the donor ribbon, and a portion of the non-visible light that is not absorbed by the donor ribbon is sensed. The sensed non-visible light determines whether the portion of the donor ribbon to which the non-visible light has been applied has unused protective donor material thereon.

Printer and method for detecting donor material

A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes hydroxyalkyl cellulose as a binder. The dye-donor element is capable of printing a defect-free image on a receiver element at a line speed of 2.0 msec/line or less while maintaining a print density of at least 2.0.

A print assembly including a dye-donor element and a receiver element, wherein the print assembly has a donor having a dye-donor layer having a first glass transition temperature and at least one dye, and a receiver having a dye-receiving layer having a second glass transition temperature on a support, wherein the print assembly has a receiver/donor dye partition coefficient of at least 2.5 when the print assembly is heated above the higher of the first or second glass transition temperature for a time sufficient to achieve an equilibrium state of dye distribution between the dye-donor layer and dye-receiving layer. The print assembly can be used at fast print speeds of 2.0 msec/line or less.

Thermal print assembly

A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes a binder including an hydroxyalkanoic acid polyester and one or more co-binder, wherein the co-binder is not polyester.

Thermal donor

A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes a polyvinylacetal copolymer as a binder.
