Method for processing light sensitive planographic printing plate material |
(57) Disclosed is a method of processing a light sensitive planographic printing plate
material comprising an aluminum support, and provided thereon, a photopolymerizable
light sensitive layer containing a polymerizable ethylenically unsaturated compound,
a photopolymerization initiator, and a polymer binder, the method comprising the steps
of imagewise exposing the light sensitive planographic printing plate material, developing
the exposed light sensitive planographic printing plate material with a developer
to obtain a planographic printing plate, the developer containing no silicate or containing
a silicate in amount of not more than 0.1% by weight in terms of SiO
2, and plate processing the resulting planographic printing plate with a plate protecting
solution containing a phosphonic acid compound at a temperature of from 40 to 90 °C.
