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.
