An optimal laser drying of offset color layers requires the direct integration of the beam source into the printing system. This is the only way to achieve a possibly effective drying and thus an efficient process control. For this, the laser head, supply unit, as well as the necessary homogenizers and line focus optics have to be integrated exactly into the given assembly space. This requires compact, individually suitable components. The diode lasers and optics of Laserline meet these demands in an optimal way: their modular and compact design makes it possible to tailor all components precisely to the individual customer’s needs. Power compromises do not need to be accepted. Despite their highly compact design, Laserline's diode lasers can easily provide powers in the double-digit kilowatt range.
