Method for producing and handling of planographic printing plate precursor

Abstract

A planographic printing plate precursor which prevents deformation and destruction of fine particles dispersed in an image forming layer thereof and has high developing performance and a high speed thin layer coating aptitude is provided. A method for producing and handling a planographic printing plate precursor having an image forming layer containing a photosensitive composition having fine particles dispersed therein is provided. The pressure acting on the image forming layer during or after formation of the image forming layer is 1.5×105 N/m2 or less. The pressure conditions are achieved by controlling any one of the pressure PL, which acts on the coating liquid during formation of the image forming layer, the sum of the PL and shear stress τ, the pressure PF, which acts at the time of transfer of the support after formation of the image forming layer, the pressure PR, which acts at the time of winding the long strip support, the pressure PP, which acts at the time of stacking the sheets of the planographic printing plate precursor, and the pressure PK, which acts at the time of storing the stock roll of the planographic printing plate precursor. The fine particles are preferably polymer fine particles.
