  • Patent number: 10688819
    Abstract: In a printing method, a coating substance is applied onto the recording medium depending on spatially resolved temperature data with regard to the temperature of the surface of a recording medium to be printed to in preparation for printing of a print image. The quality of the print image may thus be increased, in particular given the presence of an inhomogeneous curve of the temperature of the recording medium.
