Fremgangsmåde til fremstilling af sikkerhedsetiketter

摘要

The invention concerns a method for making safety labels which consists in producing a base deposit on the film (100), then in defining a label shape (101). It further consists in producing (102) a printed window preferably by photogravure with cells bordered by a stripe forming the window outline; printing (103) the printing window on the base deposit with a passivation coating, and developing the window (104) by a physico-chemical operation.
