I assume these are photopolymer plates. Put each of them in a zip lock bag. Blow into the bag before closing it (they like carbon dioxide–oxygen is their enemy). Put them in folders in a file cabinet.


Further note: Photopolymer plates, if not too old, can sometimes be revived with a carbon dioxide bath. Basically, configure an enclosed box with a shelf to hold the plate and a lower container to hold dry ice.

It’s a technique used in the earlier years of photopolymer, and, actually works, if done fairly routinely.


Nylos ?

You mean a Nylon plate ? (Spelling)

And yes, that too would be a polymerplate.

I hate to be an annoying, but you breath out only a little bit less oxygen than you breath in (roughly 21% in, and 17% out). Will help no doubt. but to be super anal, get bizzy with the fizzy.


I wonder if its time that when people hit this web site they get an explanation of where they are and what we do , then they can claim that we are mad as well as overpaid and lazy. The proof will be here , in print ,not to vary on waves of sound………….

A nylon plate (such as Nyloprint) IS a photopolymer plate. They don’t last forever, have to be protected from light and damp, for example in the sealable bag Gerald mentioned.
Last month I printed a mounted photopolymer plate that has been sitting on an open galley for 15 years, yet other plates that have been wrapped in tympan paper and stored away from light have gone bad in two years. They degrade variably.
The most important thing is to retain negatives for remakes.


So, don’t blow in the bags. No skin off of my nose.
