METHODS FOR THERMAL MASS TRANSFER PRINTING

A method of thermal mass transfer printing a colorant including a binder media from a ribbon onto a first surface of a web having a non-homogeneous thermal conductivity, a non-planar printing surface, a non-homogeneous structure or chemical incompatibility. The first surface of the web is preheated...

More Information
Summary:A method of thermal mass transfer printing a colorant including a binder media from a ribbon onto a first surface of a web having a non-homogeneous thermal conductivity, a non-planar printing surface, a non-homogeneous structure or chemical incompatibility. The first surface of the web is preheated prior to thermal mass transfer printing. The surface of the ribbon containing the colorant is positioned opposite the first surface of the heated web at an inner face. A thermal print head is positioned at the interface on the side of the ribbon opposite the colorant. The web is moved relative to the thermal print head. Printing is completed by selectively applying localized heat to the ribbon from the thermal print head and pressure at the interface to cause the transfer of colorant from the ribbon to the heated web.
