Abstract (en)
Thermal paper (1) is introduced in flash-oven (7, 8). Thermal waves are absorbed by ink, allowing ink to set. Method compris cooling of thermal layer (4) during fusion phase of ink so as to maintain temperature of thermal layer to temperature lower to toning temperature. Cooling of thermal layer starts when thermal wave touches thermal face (6) of paper. An Independent claim is also included for the apparatus used to apply fixing method.
Abstract (fr)
La présente invention concerne un procédé de fixation d'une préimpression sur papier thermique (1), consistant à refroidir la couche thermique (4) dudit papier thermique pendant la fusion de l'encre de manière à maintenir la température de ladite couche thermique à une valeur inférieure à la température de virage (T1). La présente invention concerne également le système de mise en oeuvre dudit procédé. <IMAGE>
