For example, in the field of printing materials, in order to form a desired image, a negative or positive film is first bonded in vacuum, and then active light, such as UV light, is irradiated onto it to cause a photochemical change. Solubilize or insolubilize the photosensitive developable resin composition. Next, parts other than the formed image are developed (eluted) using an appropriate developer,
Dry and post-expose to obtain the desired plate material.

は施されていない。(Problems to be Solved by the Invention) Water, acid or alkaline water, which is free from problems such as the working environment and surrounding pollution, is generally used as a developer. In this case, as shown in FIG. 3, a developer is introduced from the water inlet 21, and after developing the printing plate 22, the developer is discharged from the drain 23. At present, no special treatment has been applied to this developing waste solution.

。In such cases, recycling a portion of the developer waste and reusing it as a developer serves the purpose of saving resources and regulating the total amount of waste water. It is difficult to use it as a developing solution. If this is reused as a developer, the plate material obtained will be contaminated with eluted resin residue and cannot be used unless washed, making it impossible to achieve the objectives of saving resources and controlling the total amount of water discharged.
