Abstract
A label-printing process for obtaining a desired optical density and a desired color tone with a substantially light-insensitive elongated imaging material comprising: PA1 selecting an elongated imaging material, the selected elongated imaging material having a support and a thermosensitive element; PA1 supplying image data to a processing unit of a thermal printer including a printhead having energizable heating elements arranged in a column C; PA1 converting the image data which are not zero into at least one activation pulse per pixel to be printed; PA1 energizing the heating elements printing-line by printing-line adjacent to the selected substantially light-insensitive elongated imaging material thereby producing an image; PA1 transporting the imaging material past and adjacent to the printhead in a transport direction with a transport system; PA1 forming an image dot with a heat energy of 50 to 200 mJ/mm.sup.2 of heating element surface area; wherein the thermosensitive element contains a substantially light-insensitive organic silver salt, a reducing agent therefor in thermal working relationship therewith and a binder; and the thermosensitive element excludes a colorless or…
