Patent ID: 7688339

Claim:
Device for scribing a visible label on a medium ( 11 ), the medium having a label side provided with a radiation sensitive layer for creating the visible label by scribing a pattern of substantially parallel traces of dots via a beam of radiation ( 24 ), the device comprising a head ( 22 ) for providing the beam of radiation for generating a scribing spot on the radiation sensitive layer for scribing the visible label, a control unit ( 20 ) comprising label control means ( 33 ) for controlling the scribing in dependence of label data, and positioning means ( 25 ) for positioning the scribing spot in a transverse direction that is transverse to a longitudinal direction of the traces of dots, which positioning means ( 25 ) comprise course positioning means for course positioning the scribing spot in the transverse direction by movements of the head and fine positioning means for fine positioning the scribing spot in the transverse direction, and generator means ( 32 ) for, during at least one boundary trace of the substantially parallel traces which precedes or succeeds one of the head movements, temporarily applying a broadening signal ( 35 ) to the fine positioning means for broadening the boundary trace in the transverse direction.
