Abstract (en)
[origin: EP0943443A2] The thermochromic layer is heated for erasure. Appropriate set values of time and temperature are used, rendering the layer colorless. Localized further heating, using a different set interval and temperature, bring about color change, which is followed by rapid cooling below erasure temperature, to leave the printed points intact. The process is repeated until all rows of points have been printed. An Independent claim is included for the corresponding thermal printing equipment.
