ABSTRACT OF THE DISCLOSURE A method is provided herein for modifying the surface state of a material or a medium, in particular of the paper and/or card type for the purpose, in particular, of printing on the surface or medium. The method includes the step of substantially simultaneously applying a plurality of printing fluids on the surface of the print medium in such a manner as to provide dusting zones on the medium suitable for retaining dusting powder particles which adhere exclusively on the zones. A dusting powder is dusted onto the medium including the dusting zones, the dusting powder comprising a substance which melts on heating and which is set after subsequent cooling. Excess dusting powder is removed by means of a flow of air. The medium is then heated to fix the printing fluids and the dusting powder particles retained thereby. The heating step is performed in an atmosphere of hot air at a temperature sufficient to melt the dusting powder and having a degree of humidity sufficient to counter a large drop in the humidity of the medium under the effect of the heating.
