The invention relates to a method for the production of a digital printing ink and to the ink thus obtained. The inventive method comprises the following phases consisting in: dispersing pigments in a mixture of oligomers and monomers, including polyol acrylates, with a maximum particle size of 1 micrometer; diluting same with a mixture of monofunctional and multifunctional acrylic monomers until a viscosity of between 10 and 30 centipoise is obtained; introducing a photoinitiator system which starts the polymerisation of the oligomers and monomers from the first phase, in the presence of ultraviolet radiation; and subjecting the resulting ink to a filtration process
Le procédé de cette invention consiste à : disperser des pigments dans un mélange d'oligomères et monomères, contenant des acrylates de polyols, ayant une taille maximale de particule d'un micra, à diluer avec un mélange de monomères acryliques monofonctionnels et multifonctionnels jusqu'à l'obtention d'une viscosité comprise entre 10 et 30 centipoises, à introduire un système photoamorceur qui lancera la polymérisation des oligomères et monomères de la première phase, en présence d'un rayonnement ultraviolet, et à soumettre l'encre ainsi obtenue à un procédé de filtration.
