Abstract

Sono stati sviluppati un metodo e un dispositivo per indurire lo strato fotosensibile rimasto su lastre fotolitografiche negative per stampa, dopo esposizione, sviluppo e gommatura, mediante irradiazione prevalentemente con radiazione ultravioletta media emessa da almeno una sorgente, avente picco d'emissione a lunghezza d'onda compresa fra circa 400 nm e circa 200 nm, e presentante densità di potenza sulla lastra compresa fra circa 300 mW/cm 2 e circa 150 mw/cm2 ; dette lastre sono irradiate per un tempo molto breve, compreso fra circa 30 sec e circa 90 sec. (Fig. 1)
