[origin: DE19747302A1] The invention relates to a device (1) for inscribing thermographic material (5). The inventive device (1) comprises a heating means (20) with which the thermographic material (5) is preheated to a temperature, said temperature being lower than a writing temperature, in order to inscribe the thermographic material (5). The thermographic material (5) can be inscribed with a writing means (10) which is distanced from the thermographic material (5) after input of an information signal (s(t)). According to the invention, said writing means (10) have a plurality of individually controllable point sources (30-33; 51-53). The thermographic material (5) can be inscribed in a point-by-point manner with said point sources (30-33; 51-53).
