Title
(EN) METHOD OF INK- JET PRINTING
(FR) PROCÉDÉ D'IMPRESSION À JET D'ENCRE
Abstract
(EN) The present invention provides a method of inkjet printing comprising: (a) providing a colourless inkjet ink comprising at least 30% by weight of a monofunctional (meth)acry!ate monomer based on the total weight of the ink and a photoinitiator; (b) jetting the ink on to a substrate; and (c) exposing the inkjet ink to actinic radiation, wherein the ink is printed in a multi-pass mode and the first exposure to actinic radiation of the ink in the final pass commences during a time interval of from 0.2 to 1.6 seconds from the ink impacting the substrate.
(FR) La présente invention concerne un procédé d'impression à jet d'encre comprenant les étapes suivantes: (a) la mise à disposition d'une encre incolore pour jet d'encre comportant au moins 30% en poids d'un monomère de (méth)acrylate monofonctionnel basé sur le poids total de l'encre et un photo-initiateur; (b) la projection de l'encre sur un substrat; et (c) l'exposition de l'encre pour jet d'encre à un rayonnement actinique, ladite encre étant imprimée en mode multi-passages et la première exposition au rayonnement actinique de l'encre lors du passage final débute lors d'un intervalle de temps compris entre 0,2 et 1,6 secondes depuis l'instant d'impact de l'encre sur le substrat.
