The labels are made with a method defined "photo-composition", as it is a process similar to photography, which uses the same materials and the same procedures.
This method is based on the use of a cathode-ray which prints special light and responsive paper, giving the following advantages over the traditional use of ink: the bar coding results are particularly resistant, while allowing a large number of passages from the optical device.
Printing labels is extremely clean, and it provides a careful and precise de-coding.
The outer surface of the labels, produced in chemical resin, does not allow any abrasion of the bar code which therefore, remains inviolable.
The material was thus designed to be archived and therefore it does not degrade over time
The labels above are compatible with most commercial software, among others, ALEPH.
