Abstract

Procédé d'impression statique pour codage de documents pourvus d'une piste magnétique. Il consiste à appliquer sur un support prémagnétisé un écran en matériau magnétiquement perméable et à soumettre l'ensemble à l'influence d'un aimant permanent dont le champ magnétique est de sens inverse à la prémagnétisation. procédé permet de réaliser des dispositifs de codage magnétique dans des automatismes utilisant des documents comptables tels que des titres de transport ou des cartes de crédit
