Abstract: A process for irradiating material in web form by means of electron beams and/or UV rays, wherein
the material is applied to a transport means,
the material on the transport means is guided through a first irradiation in which the material is irradiated on the open side,
the material is transferred from the transport means to a substrate, and
the material on the substrate is guided through a second irradiation in which the material is irradiated on the second, hitherto unirradiated, open side.
