SYSTEM FOR DETECTING OFFSET PRINTING AND MACHINE USING SAME

摘要

The invention concerns a detection system (7) for measuring at least one characteristic of an inked zone (5) comprising at least one sensor adapted to sense a light radiation reflected by said inked zone (5) and to generate a measurement signal representing at least the characteristic of the inked zone (5). Such a system further comprises at least one first optic fiber (10), adapted to convey up to the neighbourhood of the inked zone (5), a light radiation emitted by a light source (11).
