Hey all,
Noob questions here: I recently bought a bunch of prints at an estate auction and they were rolled, some quite tightly. I have no idea how long they were stored this way but I'm under the impression they may have been stored like this for years and not just to get to/from the auction.

I've seen lots of advice on here on how to roll a poster for packing, but not on how to safely unroll a poster. To start I have just un-taped the outer kraft paper to let them relax a bit but they still hold their rolled shape quite firmly. I have at my disposal a couple of blueprint hanging clamps like these: https://www.engineersupply.com/Premium- ... PC624.aspx
Just the clamps, not the frame to hang them on. Anyone use these things? I was thinking if I used them, then I can at least hold the bottom edge evenly and straight as I try to unroll them. But I don't know if the lip on the inner face designed to grip the blueprints will damage/dent a poster. I was thinking if I put some kraft paper front and back so the clamp wasn't directly touching the print?

Anyway, any advice is greatly appreciated!

the pressure of the clamp might still indent the paper

I would use magazines/bean bags on the edges and slowly unroll, let paper relax, unroll some more.

depending on the paper, how long been tubed and how tight - you got some work cut out

Ok, thanks for the advice. I'll avoid the clamps and just take my time.

Follow up question then:
Within this lot I won at the auction, there are some pieces that I intend to sell. Should I just leave these rolled/tubed or should I still try to flatten them?

If its harder on the print to be rolled, flattened, rolled again, etc, then maybe I should leave them be. But I also want to be able to get them pretty flat to be able to give a fair assessment to any potential buyer.

Thoughts?

flatten them - if buyers can't assess condition it will be reflected in bidding

if these pieces are low dollar- then it might not matter

You can try reverse rolling the prints if you feel like it won't harm the prints. I had some art printed on very heavy paper stock that was rolled for a long time and the only way I could get the prints to flatten was to take a tube and do a reverse roll. After a day in the reverse roll, I used bean bags and other weights to flatten the print completely.
