Have you changed any press chemistry lately? Did the plates sit out in bright light for a period of over 45 minutes? These are the things I would check first

Wearing out. can you explain wearout? the whole plate or spots. Are you using a one step or two step fountain. Is this the new proT or older. there is a few things that we need to clarify before proceeding. Wearout can happen everywhere even with a low quality paper. the alkalinity maybe killing the fountain or breaking down the gum in the fountain. This is what assist the protecting the plate. Are you using UV? What press do you have? do you run segregated or intergrated?

many questions

Lets see if we can get to the bottom of this
