摘要: This invention pertains to an ultrafiltration process which maintains a constant developer strength in a printing plate developing operation. Such a process enables development of more plates than conventional processes while using less developer and generating less liquid waste. The ultrafiltration process is suitable for both batch and continuous plate development operations. By this process, used developer is filtered and the fluid portion returned to the working developer solution. The filtered out remainder mass is treated with an absorber to convert it into a solid.

摘要: This invention discloses a novel process to maintain constant developer strength in a printing plate manufacturing operation. Such a process enables development of more plates than conventional processes allow, while at the same time using less quantity of developer and generating fewer liquid waste. The process is suitable for both batch type and continuous plate development operations. The invention also describes an apparatus suitable for the above-described process.
