The invention concerns a method for cross-linking photosensitive inks in particular polymerisable inks (36) by ultraviolet radiation consisting in a step (35) inking dots (31) on a base (38) and a subsequent step consisting in applying a concentrated ultraviolet beam (32) on the inked dots (31), except for the base non-inked surfaces (30). The beam is in particular an ultraviolet laser beam. The invention is applicable to jet dot-matrix printing and polychromy.
L'invention concerne la réticulation d'encres photosensibles notamment d'encres (36) polymerisables par rayonnement ultraviolet. L'invention prévoit un procédé de réticulation d'encres photosensibles comportant une étape (35) d'encrage de points (31) d'un support (38) et une étape ultérieure consistant à appliquer un faisceau (32) ultraviolet concentré sur les points (31) encrés, à l'exclusion de surfaces (30) non-encrées du support. Le faisceau est notamment un faisceau de laser ultraviolet. Application à l'impression point par point par jet d'encre et à l'impression en polychromie.
