Abstract: Provided is a developer for processing planographic printing plate precursors which is characterized by having a non-reducing saccharide with two or more monosaccharides combined together and a pH equal to or greater than 6 and equal to or less than 14. The developer has a pH that is stable with time, and enhanced film formability. The developer enables a method for preparing planographic printing plates to prepare a planographic printing plate even in one step of simplified processing with one fluid without a step of washing in water, the planographic printing plate being improved in developability and the property of scattering development residues to prevent a non-image portion from becoming dirty. Also provided is the developer that is used for the method. Further provided is a method for printing by employing the method for preparing planographic printing plates.

Abstract: According to a method of preparing a lithographic printing plate comprising processing a lithographic printing plate precursor having a photosensitive layer containing a hexaarylbiimidazole compound and a protective layer with a developer containing a specific organic solvent and at least any of a surfactant and a water-soluble polymer compound, the occurrence of development scum is prevented and both good developing property and printing durability can be achieved. Further, since it becomes possible to conduct one bath processing with a weak alkaline developer, advantages, for example, simplification of processing steps, consideration for global environment and adaptation for space saving and low running cost can be achieved.
