Problems solved by technology
The problem with this device is that conventional UV lamps have a limited lifetime due to erosion of the electrodes and due to the number of switching times required before the UV radiation becomes effective
[0008] The complexity of the described device for separating the region of the irradiation device from the region in which microwave radiation is applied to the printing agent or printed material is not only considerable and cost-intensive, but also prone to damage due to this complexity

Embodiment Construction
[0040] FIG. 1 shows a schematic side view of a melting device 1 as a heating device. Thus, the melting device 1 comprises a microwave source 2 which directs microwave radiation via a microwave input line 4 to a microwave heater 5 . In turn, the microwave heater 5 comprises a microwave application zone 6 , wherein in the case shown here an irradiation device configured as a gas discharge lamp 8 is provided.
[0041] The printed material 10 is conveyed through the microwave heater 5 . In this way, the printed material 10 is conveyed and guided by conveying and guiding elements not shown here. The printed material 10 can be paper, for example. The printed material 10 moves along a transport path 11 indicated by arrows. The printed material 10 is guided through the microwave heater 5 because it is guided through the slits 12 and 13 .
[0042] FIG. 2 shows a side view of a schematic representation of the melting device 1 . In this case, in addition to the above-mentioned eleme...

The invention relates to a heating device (1) for heating at least one printing agent provided on a printing material (10), said heating device comprising at least one microwave applicator (5) for bombarding the printing material (10) with microwave radiation, and comprising at least one irradiation arrangement (8) for irradiating and melt-depositing the printing agent by means of electromagnetic radiation; as well as to an appropriate method for heating at least one printing agent. A heating device (1) and a method are to be provided which allow a design that is less complex overall. In accordance with the present invention this object is achieved, considering the apparatus, in that the radiation arrangement (8), as well as the printing material (10) and the printing agent, are bombarded by the microwave radiation of the microwave applicator (5), so that the irradiation arrangement (8) is excited to emit electromagnetic radiation.
Description
technical field [0001] The invention relates to a heating device for heating at least one printing agent applied to a printing material, said heating device comprising at least one microwave heater for bombarding the printing material with microwave radiation and at least one An irradiation device that irradiates and melts the deposited printing agent with radiation. Furthermore, the invention relates to a method for heating at least one printing agent applied to a printing material by bombardment with microwave radiation and irradiation with a radiation source while heating with microwave radiation. Background technique [0002] In virtually any printing process, solid or liquid printing agents such as dyes, inks, lacquers or toners are applied to the printed material. During the continuation of the printing process, the liquid printing agent or part of the liquid printing agent must be evaporated or the solid printing agent or part of the solid printing agent must be fuse...
