System and method of employing indicia on web material and web material using same

摘要

A donor web for use in a thermal transfer printer comprises a foil having a transfer side and a non-transfer side. A layer of thermal transfer material is disposed on the transfer side of the foil material. Indicia is ink-jetted to the foil. The indicia includes information pertaining to at least one of the length of used foil and the length of unused foil so that an operator can determine whether there is enough foil left for a printing operation. Preferably, the indicia is disposed on the non-transfer side and at a longitudinal edge portion of the foil in order to not affect or otherwise damage the printing portion of the foil. Also, the indicia is preferably white or black ink in order to be clearly visible against various colors of the thermal transfer material. The indicia can also be disposed on a receiver web.
