Abstract

L'invention concerne un procédé pour le séchage-désorption de plaques de flexogravure, lesdites plaques étant préalablement gravées puis lavées par un solvant approprié, puis placées dans une enceinte de séchage, caractérisé en ce qu'il consiste à exposer les plaques placées dans l'enceinte à l'action d'au moins un rayonnement en l'absence de circulation d'air chaud.The invention relates to a method for the drying-desorption of flexo-engraving plates, said plates being previously etched and then washed with a suitable solvent, then placed in a drying chamber, characterized in that it consists in exposing the plates placed in the enclosure with the action of at least one radiation in the absence of circulation of hot air.

Ce rayonnement peut consister en une irradiation infrarouge et/ou un rayonnement hyperfréquence.This radiation may consist of infrared radiation and / or microwave radiation.

L'invention concerne également une enceinte de mise en oeuvre du procédé.The invention also relates to an enclosure for implementing the method.
