Abstract

Fabrication de plaques d'impression en creux. On part d'une matière photosensible comprenant une feuille de base transparente 1 et une couche photopolymérisable 2. On expose la matière photosensible conformement au négatif d'un dessin en grille 3, on expose ensuite (parfois même en même temps) à travers la feuille de base conformément à un positif de l'image que l'on veut imprimer. Cela fait, on développe la matière de manière à laisser subsister un ensemble de cellules de profondeurs différentes correspondant aux zones de l'image que l'on désire imprimer. Ce procédé est beaucoup plus simple et beaucoup moins coûteux que les procédés de la technique antérieure.
