摘要
A laser thermal system that uses a dye donor produces a desired relationship of exposure to density by modifying the input current waveform supplied to the exposure source. The modification is a combination of amplitude modulation and pulse width modulation in an imagewise fashion. The efficiency and the speed of image formation is increased by bringing the dye donor temperature near the threshold of dye transfer using a segment of the total current waveform for a very short duration.
