Abstract (en)

A label-printing process for obtaining a desired optical density and a desired colour tone with an elongated imaging material comprising the steps of: selecting an elongated imaging material; supplying image data to a processing unit of a thermal printer including a printhead having energizable heating elements arranged in a column C; converting the image date, which are not zero into at least one activation pulse per pixel to be printed; energising the heating elements printing-line by printing-line adjacent to the selected elongated imaging material thereby producing an image; transporting the imaging material past and adjacent to the printhead in a transport direction with a transport means; characterized in that the selected elongated imaging material includes a support and a thermosensitive element containing a substantially light-insensitive organic silver salt; and a heat energy of 50 to 200mJ/mm<2> of heating element surface area is used for the formation of an image dot; and an apparatus therefor. <IMAGE>
