Patent ID: 8360568

Claim:
A method for printing on a substrate, in particular a textile substrate, with the aid of an inkjet printing device, wherein a print image to be printed is constructed by drop-by-drop deposition of one or more ink fluids in picture elements which together form the print image, an ink fluid comprising at least one predetermined concentration of at least one dye in a main solvent, which method comprises the following steps: determining colour value of a picture element from the print image, determining one or more dye-comprising ink fluids to be applied to the picture element, in dependence on the determined colour value, determining colourless transport fluid to be applied to the picture element, in dependence on the determined colour value, wherein the colourless transport fluid comprises the main solvent of the ink fluid, determining a colourless auxiliary fluid, comprising rheology-modifying agents, to be applied to the picture element, in dependence on the determined colour value, wherein the auxiliary fluid comprises the main solvent of the ink fluid, in which the rheology-modifying agents are incorporated, and applying one or more ink fluids, the transport fluid and the auxiliary fluid to the picture element.
