Abstract

Un circuit d'attaque (112,226) produit une pluralité d'énergies d'attaque auxquelles sont associées une pluralité de répartitions thermiques qui interagissent avec des supports d'impression (14) pour former des images binaires présentant des zones actives et inactives. Un circuit de commande d'attaque (103) réagit avec les informations d'image sources pour appliquer des énergies d'attaque sélectives à des éléments chauffants sélectionnés (56a, 56b, 222). Ces énergies d'attaque produisent des répartitions thermiques permettant de positionner sélectivement des frontières entre les zones actives et inactives.
