The present invention relates to an improved method for reclaiming and recycling developing solvents used in the production of flexographic printing plates. More specifically, the invention relates to reclaiming and/or recycling of the developing solvent through centrifugation and/or filtration. According to the invention, the solvent used in developing printing plates can be reclaimed and/or recycled by simply centrifuging the polymer-contaminated solvent. In certain embodiment, the centrifuged solvent is further filtered. The process involves transferring the contaminated solvent, from a plate processor or a dirty holding tank, to a centrifuge, and centrifuging the contaminated solvent to remove the polymer. The reclaimed solvent can be transfer directly back to the plate processor or to a clean holding tank.
本发明涉及一种用于回收和循环利用柔版印刷印版生产中所用显影溶剂的改进方法。更具体地说,本发明涉及通过离心和/或过滤回收和/或再循环显影溶剂。根据本发明,只需对被聚合物污染的溶剂进行离心,即可回收和/或循环使用显影印版所用的溶剂。在某些实施方案中,离心溶剂会被进一步过滤。该工艺包括将受污染的溶剂从印版处理机或脏污容纳槽转移到离心机中,然后对受污染的溶剂进行离心以去除聚合物。回收的溶剂可直接转回到平板处理机或清洁的容纳槽中。
