Here is provided a method of printing on a substrate, the method comprising: providing a substrate, wherein the substrate has been primed by a primer composition comprising water, an epoxide crosslinker, polyethyleneimine and a glycol co-solvent, the primer composition having formed a primer layer on the substrate, and printing an electrostatic ink on the primer layer. A fluid set comprising the primer composition and an electrostatic ink is also described herein. L'invention concerne un procédé d'impression sur un substrat, le procédé comprenant : l'utilisation d'un substrat, le substrat ayant été prétraité par une composition de primaire comprenant de l'eau, un agent de réticulation époxyde, une polyéthylèneimine et un co-solvant glycol, la composition de primaire ayant formé une couche de primaire sur le substrat, et l'impression d'une encre électrostatique sur la couche de primaire. L'invention concerne également un ensemble de fluides comprenant la composition de primaire et une encre électrostatique.
