Paper and cardboard responds very well to the wavelength emitted by CO2 laser beams. That makes paper digital converting extremely efficient. Being a non-contact process, laser finishing avoids the risk of deformation or distortion of the base material, always ensuring clean cuts and square edges, even with the most intricate designs. For those reasons, cutting and marking are the obvious applications of laser paper processing. Owing to their accuracy, El.En.'s CO2 laser sources are also used in applications such as laser kiss cutting and laser micro-perforation, especially in the packaging and decorating.
