The invention relates to a method for heating and fixing an inking, particularly a toner powder on a plate-shaped support, according to which the inking applied to the coated upper side of the support is fixed on the support by heat action. The aim of the invention is to be able to fix toner inkings on thick-walled supports whereby adhering well thereto. To this end, the coated upper side and/or the uncoated underside of the plate-shaped support is subjected to the action of infrared radiation and/or of a hot air stream and/or of a microwave radiation, and a support having a high weight per unit area is used, which permits a portion of the infrared radiation and/or hot air stream and/or microwave radiation directed onto the uncoated underside of the support to pass through while absorbing another portion of the same.
L'invention concerne un procédé permettant de chauffer et de fixer une couche de couleur, notamment de la poudre de toner sur un support sous forme de plaque, selon lequel la couche de couleur appliquée sur la face supérieure recouverte du support est fixée sur ledit support sous l'effet de la chaleur. Des couches de couleur de type toner sur des supports à parois épaisses peuvent être fixées avec une bonne adhérence, du fait que la face supérieure recouverte et/ou la face inférieure non recouverte du support sous forme de plaque sont soumises à l'action de rayons infrarouges et/ou d'un flux d'air chaud et/ou de rayonnements par micro-ondes et qu'on utilise un support de grammage élevé, qui laisse passer une partie des rayons dirigés sur la face inférieure non recouverte du support et en absorbe l'autre partie.
