Smudging and/or linting of resin printing plates is prevented or reduced by treating the plates with a flurocar- bon surface active agent having a perfluoroalkyl group with 4 to 14 carbon atoms. The surface active agent may be anionic, cationic or ampholytic and may be used in an aqueous, alcohol or aqueous-alcohol solution.
用具有 4 至 14 个碳原子的
全氟烷基的
氟碳表面活性剂处理印版,可以防止或减少
树脂印版的污点和/或起毛。 表面活性剂可以是阴离子、阳离子或两性离子,可以在
水溶液、醇溶液或
水醇混合溶液中使用。
