SISTEMA E PROCEDIMENTO DI REGOLAZIONE E CONTROLLO DELLE PRESSIONI DI CILINDRI DI STAMPA IN UNA MACCHINA DA STAMPA FLESSOGRAFICA A TAMBURO CENTRALE

摘要

A system for adjusting and monitoring the pressures of the printing rollers of a flexographic printing machine, which comprises at least one reader which is adapted to be placed at the printing rollers of the printing machine. The reader is adapted to detect the contrast of the print on the printing material wrapped around the central drum of the printing machine and is connected to a processing unit which is adapted to determine and control, as a function of the contrast detected by the reader, the position of the printing rollers with respect to the central drum in order to achieve the desired print.
