There is disclosed a method of processing a lithographic printing plate which comprises the steps of exposing, developing and baking the plate, in which a pre-baking liquid is applied to the plate prior to the baking step, and which is not tacky, has a long storage life, and does not require rinsing with water after baking. The pre-baking liquid includes one or more of a sulphosuccinamate or sulphosuccinate and of a type and present in an amount sufficient to form a non-water soluble baked coating on the developed plate which acts as an effective barrier to contaminating material tending to come into contact with the developed areas of the plate during the baking step, and which has no adverse reaction with the image and non-image areas and allows the plate to be baked, and thereby to improve the durability of the processed plate for use on a press. The baked coating is removed subsequently by an alkaline solution. |
