A process including selecting an ink having a viscosity that varies continuously over a range of transfuse process temperatures; forming an image on a preliminary receiving surface or on a final receiving substrate with the selected ink; providing a final receiving substrate at a selected temperature optionally comprising modifying the temperature of the final receiving substrate to achieve a selected temperature; optionally passing the final receiving substrate through a nip; optionally exerting pressure on the final receiving substrate in the nip to transfer the ink image from the preliminary receiving surface to the final receiving substrate; optionally fusing the ink image onto the final receiving substrate at a transfuse temperature; and controlling the viscosity of the ink during printing to match a selected characteristic of the final receiving substrate; and preserving the ink image.
