Abstract

L'invention porte sur un procédé pour sécher des matières imprimées. Le procédé comprend les étapes suivantes : l'utilisation de deux électrodes (1) avec une différence de tension, la formation d'une couronne de champ électrique entre les deux électrodes par une tension élevée, et le passage d'un substrat (3) avec une couche d'impression (2) à travers les deux électrodes de décharge électrique à haute tension (1) dans la condition de décharge du champ électrique. Des liaisons insaturées contenues dans la couche d'impression (2) sont rompues, de façon à former des composés à liaison longue sous l'action du champ électrique, de façon à produire ainsi un durcissement et un séchage. Ledit procédé présente des avantages d'économie d'énergie, de protection de l'environnement et de rendement de production élevé. L'invention porte également sur un dispositif, qui a une structure simple et un faible coût.
