It is equipped with a tank for storing the developer, and performs rubbing development with a brush etc. while immersing the photosensitive resin plate in that tank or a tank prepared separately, or by circulating the developer from the tank with a pump etc. It is supplied to the resin plate and rubbed with a brush.

にくくなることがあった。In such a conventional method, since the scraped-off photosensitive resin component is mixed in the developing solution, the resin concentration in the developing solution increases as the number of developed photosensitive resin plates increases. That is, since the developing solution is fatigued, the developing performance of the photosensitive resin plate is different between the case of a new developing solution and the case of a developing solution in which fatigue is advanced, so that it is difficult to perform stable development from beginning to end. Also, in the case of a circulation type automatic developing machine, since the developer containing the photosensitive resin component is used for development while circulating, the photosensitive resin component adheres and accumulates inside the liquid circulation pipe, etc. There was a case where the developer was blocked and the supply of the developer became difficult.

かった。Further, in general, the developing solution tank is equipped with a heater for raising the temperature of the solution, and the developing solution containing the photosensitive resin component is heated by the heater so that the photosensitive resin is Since the components may aggregate, it was not easy to clean the resin adhering to the heater after using the automatic developing machine.

液の排出量が増える要因となっていた。In recent years, consideration for the environment has become indispensable, and the used developing solution is appropriately drained and then drained, or a waste solution processing company is requested to pick up the solution. Then, even if the number of developed photosensitive resin plates is small, the developer is replaced, which is a factor of increasing the discharged amount of the used developer.

出量の削減には寄与できていなかった。In order to solve these problems, an automatic developing machine for photosensitive resin letterpress called "FTP460III" manufactured by Toray Industries, Inc. is sold. Since the developing machine supplies the unused developing solution only when the brush rubbing development of the photosensitive resin relief printing plate is performed, stable development is possible from beginning to end. Further, by constantly supplying the unused developer, it is not necessary to circulate the developer containing the photosensitive resin component, so that clogging of the liquid circulation pipe can be avoided. Furthermore, since the developer containing the photosensitive resin component is discharged out of the machine as it is, aggregation of the photosensitive resin component due to the temperature rise of the heater is also eliminated. However, in this developing machine, the amount of the developing solution used is as large as about 4 liters per minute, and it has not been possible to contribute to the reduction of the discharged amount of the used developing solution.
