Can anybody explain what could cause- in a cyan ink- the oxidation? of the cyan plate. It only happens in cyan after a prolonged press stop. Change the ink to another supplier and the problem disappear. I am not sure that it is oxidation but the non-image area becomes not clean anymore in the normal process.

Thanks in advance
