Beschreibung
Zusammenfassung:	A method for processing a lithographic printing plate comprising development with an alkaline solution and gumming with a first gum solution and subsequently with a second gum solution, wherein both gum solutions are provided in a cascade configuration whereby the second gum solution overflows into the first gum solution and wherein an alkaline silicate-free developer is used. La présente invention concerne un procédé de traitement d'une plaque d'impression lithographique comprenant le développement avec une solution alcaline et le gommage avec une première solution de gomme et ensuite avec une seconde solution de gomme, les deux solutions de gomme étant fournies dans une configuration en cascade dans laquelle la seconde solution de gomme déborde dans la première solution de gomme, un développeur sans silicate alcalin étant utilisé.
