Abstract: A method for determining a tonal vector for generating a control signal for a printing device includes providing a device-independent color value vector. The method includes transforming the device-independent color value vector into the tonal vector using a backward transformation. The method includes determining the backward transformation such that a cost function including an image difference metric term is minimized. The image difference metric term represents a difference between a reference image including device-independent color value vectors and a simulated image. The simulated image is determined by transforming an input image into a tonal image using the backward transformation and transforming the tonal image into the simulated image by using a forward transformation.

Abstract: A method for three-dimensional printing includes dithering a set surface of the printing object and printing the printing object with the dithered surface. The dithering includes determining the set surface of the printing object, providing a spatially high-frequent dithering signal, and modifying the set surface as a function of the dithering signal. A non-transitory computer-readable medium includes instructions that implement the method. A 3D printing device includes a printing device and a control unit configured to control the printing device using the method.
