摘要： A method for monitoring a characteristic of a printed image of a thermal transfer printer. The method comprises providing a ribbon and a substrate at a printing location of the thermal transfer printer. The method further comprises printing an image on the substrate at the printing location by transferring ink from a region of the ribbon in a printing operation, a negative image being formed on the region of ribbon. The method further comprises transporting the region of ribbon, by a ribbon transport system, from the printing location towards an imaging location along a ribbon transport path. The method further comprises when a characteristic of the ribbon transport meets a predetermined criterion, obtaining, by an image capture system, a ribbon image of the negative image. The method further comprises processing said ribbon image to generate data indicative of the characteristic of the printed image.

摘要： A printer includes a thermal print head (111), a supply shaft (120), a winding shaft (130), a light emitting device (141) , and a photodetector (142). The light emitting device and the photodetector are aligned along a line parallel to a line passing through rotational axes (O1, O2) of the supply and winding shafts at a predetermined distance. The predetermined distance is greater than a radius of the supply shaft and a radius of the winding shaft. The predetermined distance is less than a radial distance from the rotational axis of the supply shaft to an outer surface of the ink ribbon on the supply shaft and a radial distance from the rotational axis of the winding shaft to an outer surface of the ink ribbon on the winding shaft when a length of the ribbon on the supply shaft is equal to a length of the ribbon on the winding shaft.

摘要： There is provided a thermal transfer sheet capable of being identified by a thermal transfer printing apparatus, as well as being capable of preventing color property changes in high-resolution printing and reducing production cost. The thermal transfer sheet (5) of an embodiment includes a dye layer (52) and a protective layer (54) on one surface of a substrate (50). The protective layer (54) contains an invisible light absorbing material and is provided with an identification mark (55) having at least one of a recessed portion and a protruding portion.
