Abstract

La présente invention concerne un procédé d'impression offset utilisant une encre d'impression à l'eau. La conduite du processus nécessite une hygrométrie se situant entre 75 et 100 %, et de préférence une température comprise entre 10 et 30 DEG C. L'encre à l'eau utilisable avec ce procédé est constituée d'eau, d'un liant macromoléculaire, d'un pigment et d'un lubrifiant. Le liant macromoléculaire: (i) peut être éventuellement présent et de type hydrosoluble quel que soit le pH de la phase aqueuse, ou (ii) être présent et de type hydrosoluble uniquement pour une valeur définie du pH, ou (iii) être éventuellement présent et sous forme d'une émulsion dans l'eau. Un agent tensio-actif non ionique peut également être présent dans l'encre.
