Abstract

Sono stati sviluppati un metodo e un'apparecchiatura per la mattatura di lastre da stampa fotosensibili (1); il metodo è basato sulla spruzzatura di un fascio goccioline finemente suddivise di una composizione poco viscosa di una o più sostanze adatte per mattatura e di un solvente, in modo che, per evaporazione di gran parte del suddetto solvente, le suddette goccioline siano molto viscose quando raggiungono lo strato fotosensibile, vi aderiscano, e si asciughino rapidamente, formando minuscole protuberanze; l'apparecchiatura comprende mezzi di spruzzatura (5) capaci di indirizzare sulla suddetta lastra da stampa (1) il suddetto fascio di goccioline finemente suddivise.(Fig. 1).
