Abstract: In a method for printing on a substrate, in particular a textile substrate, with the aid of an inkjet printing device, 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. The method includes for this purpose the following steps: (a) the determination of the color value of a picture element from the print image, (b) the determination of one or more dye-comprising ink fluids, in dependence on the determined color value, (c) the determination of colorless transport fluid to be applied to the picture element, in dependence on the determined color value, (d) the determination of a colorless auxiliary fluid, comprising rheology-modifying agents, in dependence on the determined color value, and (e) the application of the ink fluids, the transport fluid and the auxiliary fluid to the picture element.

The method comprises for this purpose the following steps: • the determination of the colour value of a picture element from the print image, • the determination of one or more dye-comprising ink fluids, in dependence on the determined colour value. • the determination of colourless transport fluid to be applied to the picture element, in dependence on the determined colour value, • the determination of a colourless auxiliary fluid, comprising rheology-modifying agents, in dependence on the determined colour value, and • the application of the ink fluids, the transport fluid and the auxiliary fluid to the picture element.

Abstract: In a method for printing a substrate which is provided with a polymeric ink-receiving layer with ink drops according to the “drop-on-demand” principle, using an ink jet printing device, the printhead of which is provided with a piezo element for generating ink drops, the method comprising the steps of supplying the substrate, generating ink drops and depositing the generated ink drops on the substrate, the ink from which the ink drops are formed, has an ink composition which comprises a dye, water, a lower alcohol and humectant, the lower alcohol content thereof being 5-30% by weight.
