METHOD AND DEVICE FOR THERMALLY TRANSFERRING RECORDING

摘要

PROBLEM TO BE SOLVED: To provide a method and device for thermally transferring recording capable of executing high quality intermediate gradation recording by utilizing a light emission device array wherein a plurality of light emission devices are juxtaposed in a main scanning direction. SOLUTION: A plurality of light emission devices each of which has a length in a sub-scanning direction is longer than a recording pixel are juxtaposed in a main scanning direction. The emission light generated by applying a voltage pulse to each of the light emission devices 1a is passed through an optical lens 2 capable of collecting the light in the sub-scanning direction to be made the collected light of which length in the sub-scanning direction is shorter than the recording pixel and to be emitted on an ink donor film 10. A voltage is repeatedly applied to the light emission device 1a so that the collected light is repeatedly emitted on a region to be melted on the ink donor film 10 in accordance with density data of each pixel and the ink donor film 10 is conveyed. The ink donor film 10 is intermittently conveyed by an interval shorter than the length of the recording pixel in the sub-scanning direction. An area of a dot in the recording pixel is varied to represent the intermediate gradation density.
