Abstract (en)
A printing process for a substantially light-insensitive thermographic monosheet material having two edges parallel to one another and > 12 cm apart (non-label) for obtaining a desired optical density and a desired colour tone comprising the steps of: selecting a thermographic monosheet material, the selected thermographic monosheet material being a black and white thermographic monosheet material having a support and a thermosensitive element; 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 data 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 substantially light-insensitive thermographic monosheet material thereby producing an image; transporting the imaging material past and adjacent to the printhead in a transport direction with a transport system; characterized in that a heat energy of 50 to 200mJ/mm<2> of heating element surface area is used to form an image dot; 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 an encapsulated organic silver salt in a heat-responsive microcapsule.
