FIELD: printing.
SUBSTANCE: device for irradiating substrate material (S) in form of a sheet or web in a sheet-fed or web-fed processing system, especially in a sheet-fed or web-fed printing press. Device comprises at least one flexible light-emitting sheet (10) for producing radiation of a desired wavelength or wavelength band; which flexible light-emitting sheet (10) is disposed along a path of substrate material (S) to subject substrate material (S) to radiation. Flexible light-emitting sheet (10) is a sheet of organic light-emitting device.
EFFECT: irradiation of substrate material.
