Best way to flatten out posters

sanangelohorn

Just got back home from my first 2 shows picked up 2 of each of the posters. I need to start the flattening process and wanted to know the best methods. I was thinking about slipping them into a broken down box's and placing books on the them but I'm sure someone else here know of a better way.

Put them on a table with at least 4 books on the corners.  Depending on how long they were rolled it could take a day or a few to be completely flat before framing.

I buy cheap poster frames and store them that way

2 pieces of thick foam posterboard + acid free paper (front and back) + 10-15 binder clips. Then put under my mattress for a while.

The best idea. My problem has always been that I cannot find poster board and glassine paper without having to buy a stupid amount in bulk through ULine. Sometimes it sucks having prints beyond 18" x 24" or the occasional odd shape (looking at you Hale NYC 2015).

I collect movie posters and use heavy books....that, and time, will flatten your posters just fine for framing.

I use a presentation board to store my posters flat.  It works great!  I have a layer of kraft paper between each one, and I use big binder clips to hold the presentation board closed.  It's cheap and will hold plenty as well, I probably have 40 posters in mine right now.

I'll second this as it's the method I use.  I use glassine sheets in between each poster but any acid-free paper will do fine.

If the poster has been in a tube for a long time (like a month or more), let it relax on its own for a couple days then transfer it to the display board. If it's only been in a tube for a short time, you can go straight to the display board without fear of the ink cracking or anything.

This is only after they have been flattened, correct?

I use NES games to flatten mine. With poster/craft paper between the poster and the games.

I got something like this.  First i lay them on a table with weights on the corners for a couple of days, usually with some acid free paper over it. Then i store them in the portfolio, which i also lay flat with weights, and I use a small piece of particle board in the back so nothing gets bent.

And time.

As others say, just unroll it and put weight on it, though I wouldn't recommend just pinning corners down. Evenly distribute the weight all over the poster. Leave it for a long time. Like 2 weeks.
After that, I put them in a big zip up portfolio that I bought at Michael's for $40 or something. I lined it with foam board to keep it rigid. I can fit probably 25 posters in there, including the paper in between each one (I just use the same paper that the poster comes with).

Nope, I use the presentation boards for both the flattening time and post-flattened storage.  When flattening, I tape the board shut and evenly distribute weight on top.

I lay it on a table under some books and use a hammer to flatten out any high spots.
