Zusammenfassung:This invention is directed to a method of a radiation induced printing comprising the following steps: printing a printing ink comprising effect pigments on an ink carrier, which is optically transparent at a certain wavelength; followed by irradiating the ink carrier by means of an energy-emitting apparatus emitting energy in the form of electromagnetic waves, wherein the printing ink absorbs energy of the electromagnetic waves and undergoes a change in volume and/or position causing a transfer of droplets of the printing ink from the ink carrier to an imprinting material, wherein the printing ink comprises an effect pigment mixture containing flaky pearlescent pigments and flaky metal effect pigments.
