Abstract
A method for producing a printing plate, containing: an exposure step of forming a relief by the exposure of a photosensitive resin composition; and a developing step of performing development by attaching or adsorbing the photosensitive resin composition of an unexposed portion in the exposure step to a development medium, wherein a storage elastic modulus of the photosensitive resin composition of the unexposed portion at a development temperature of the developing step is 100 Pa or more and 4000 Pa or less, and the development medium is a wiper having an elastic recovery rate of 30% or more and 99% or less.
Claims11
A method for producing a printing plate, comprising:
- molding a photosensitive resin composition that is liquid at room temperature to form a molded photosensitive resin composition;
- exposure by forming a relief by the exposure of the molded photosensitive resin composition;
- and
- developing by performing development by attaching or adsorbing the photosensitive resin composition of an unexposed portion in the exposure to a development medium, wherein
- a storage elastic modulus of the photosensitive resin composition of the unexposed portion at a development temperature of the developing is 100 Pa or more and 350 Pa or less, and
- the development medium is a wiper having an elastic recovery rate of 40% or more and 99% or less.
