description A method for transferring a printing substance provided as a coating on a carrier onto a substrate by laser radiation from a laser beam source that comprises an amplifier and that has an output power includes initiating a transfer process at the start of an active phase during a first time period by a temporary increase in the output power above an upper power threshold of the laser radiation, and adjusting the output power during a second time period of the active phase following the first time period, wherein the output power is adjusted during the second time period constantly in the range between the upper power threshold and a lower power threshold. The laser radiation and the carrier are moved relative to one another and the output power of the laser beam source is time modulated.
