Printing ink tempering device for rotary printing press, has laser emitter emitting electromagnetic waves whose wavelength essentially corresponds to absorption maximum of printing ink that is fed to rubber blanket

摘要

The device has a laser emitter (5) that finds its application for tempering printing ink, where the laser emitter emits electromagnetic waves. Wavelength of the electromagnetic waves emitted by the laser emitter essentially corresponds to absorption maximum of the printing ink that is fed to a rubber blanket (41). The rubber blanket of an offset cylinder works together with a dry offset plate.
