"Can print maker prevent ink discoloration on etching plates?"



2005


I am a print maker and am having trouble with the pigments in my inks changing color or discoloring when using zinc or nickel as my etch plate can you tell me if I can prevent this by wiping fist (before inking up) with sodium hydroxide?

Without knowing exactly what is causing the discoloration (most probable cause are oxides that are reacting with something in your inks), I can tell you not to wipe the zinc plates with caustic soda. They will be severely attacked. Nickel will not be attacked by this mixture but it may simply not fix the problem. G. Marrufo-Mexico
