Abstract

L'invention concerne un procédé d'impression d'une image d'impression (D) sur des substrats (3) en particulier incurvés, comprenant une première étape dans laquelle une sélection (2') de réceptacles d'encre (2) formés par des protubérances ou des creux de la surface d'un support d'encre (1) flexible et/ou étirable et répartis sur toute la surface du support d'encre (1) est munie d'encre d'impression au moyen d'un procédé d'impression numérique, la totalité des réceptacles d'encre (2) munis d'encre d'impression reproduisant l'image d'impression voulue (D), comprenant une deuxième étape dans laquelle le support d'encre (1) portant ses réceptacles d'encre (2) munis d'encre d'impression est mis en contact avec le substrat à imprimer (3), comprenant une troisième étape dans laquelle on effectue par un procédé de durcissement un durcissement de l'encre d'impression contenue dans les réceptacles d'encre (2), et comprenant une quatrième étape dans laquelle le support d'encre (1) est enlevé du substrat (3) et l'encre d'impression durcie reste sur le substrat (3) à imprimer.
