20100013875 | Printing Method And Ink Jet Printing Device - 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 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. | 01-21-2010 |
