Iron it under a blanket

Step №1: carefully fold it along the creases, as it was stored. Step №2: go fold by fold, bending them in the opposite direction such that each crease gets flattened out. Step №3: press it between two very flat panels, if possible store it like that forever. For instance: wooden or MDF backplate, put some cardboard between the poster and the backplate. then use either a Perspex or glass front, press them together. Step №4: add a frame. Step №5: ??? Step №6: PROFIT! Your poster is now de-creased as best as possible and stored correctly. Never take it out of the frame / glass with backplate. Hang it up like this. If you wanna go super-fancy you can use brushed steel or aluminium as backplate to show proper respect for 2nd best girl of NGE…

nice poster

It cannot be done since the paper is already permanently bent

>>6210 You reminded me of this gem, also

>>6307 My room isn't that dirty. And I only have 3 anime posters

Spray a bit of water. Humidity relaxes the fibers such that they can be easily reshaped... Which is why it's so easy for it to warp in all sort of ways as it dries out. Just find a way to keep it flat and stretched while it dries out and don't let it dry out to fast. >>6216 Or this, is basically the same, you're just relaxing the fibers with heat instead of water. But it takes more physical effort ime. I guess you could use a slightly damp blanket...

>>6412 doesn't work, if the poster is varnished. I'll only shrivle up. There are restoration liquids, which is like a glycol compound you soak the poster in and then press it between two flat panels to dry it. Just water will destroy it further.
