Abstract

A method for heating and fixing an inking, particularly a toner powder on a plate-shaped support. Heat is applied and fixes the inking to a coated upper side of the support. The method of this invention can be used to fix and adhere toner inkings on thick-walled supports. In one method step of this invention, the coated upper side and/or an uncoated underside of the plate-shaped support each is subjected to infrared radiation and/or a hot air stream and/or a microwave radiation. At least a portion of the infrared radiation and/or the hot air stream and/or the microwave radiation directed onto the uncoated underside of the support passes through while another portion is absorbed, such as if the support has a high weight per unit area of the support. A ceramic or thermosetting toner forms the applied ink.
