[origin: WO9633872A1] The invention relates to a process and a device for curing a u/v hardening printing ink (4) on a printed material (9) in which the printing ink (14) is irradiated with u/v light from a u/v radiation source (8). A low-pressure gas discharge lamp (7) is proposed as the u/v radiation source (8). A further special feature of the device of the invention is that it has a fixed reflector (5) comprising in particular a special reflecting coating of a diffusely reflective material based on a silicone rubber with diffusely reflective particles embedded therein.
