An inkjet marking module includes an inkjet marking device adapted to jet droplets of an inkjet marking material to form an image on recording substrate; and an evaporation device arranged for evaporating a solvent to a gaseous medium. The evaporation device includes an aerosol generator for creating an aerosol of the solvent in the gaseous medium; and a droplet eliminator for removing droplets from the aerosol, the droplet eliminator being arranged downstream of the aerosol generator. A printing system includes such an inkjet marking module and a method is disclosed for controlling the relative degree of saturation of a solvent vapor in a gaseous medium in an inkjet marking module.
