Abstract (en)
A method of thermal printing with a thermal printing dye-donor (10) having a light-to-heat converting material mixed with the thermal dye material (19) on a support member (14). The method comprises the steps of superposing a receiver member transparent to an information bearing radiation beam with the support member carrying the thermal dye material. An information-bearing radiation beam (22) is generated by supplying an information-bearing power signal to a radiation-generating device, and the thermal dye material is exposed to the information-bearing radiation beam through the receiver member (12) to transfer thermal dye material from the support member to the receiver member to generate an image on the receiver member, with the image having a density which varies linearly with the power level supplied to the radiation-generating device. <IMAGE>
