Another "darkroom" question:

[Asha]

Re Wet printing:

Once exposed, can paper be stored with its latent image in a lightight environment then developed at a later date like one can do with exposed film?

Technically yes but you will be surprised how light can leak through a solid object. If you do have a go I would use the actual box the paper came in along with the black plastic bag.

Yes I have suitable empty light tight bags and "cartons" / envelopes that have housed paper

I understand that not unlike film, the sooner that development is performed the better, possibly even more so with the paper process.

I've seen references to this being used as a method of cryptography from the 19th century. The paper used was very thin and it would be hidden inside a suitable light tight container such as a fountain pen. Anyone opening the container without the correct precautions would expose the paper and wipe out the message. Once the idea got around counter espionage agents made a point of checking such things in a darkroom so the method had a short lifespan.

I've never tried this Asha, so no help there I'm afraid. My problem would be that I often wanted to tweak the exposure or the contrast grade once I'd seen the print, and that's obviously way easier when the enlarger is still set up with the negative in place for a quick reprint.
