Do you use papergraphics for any media? They’re our main supplier and we use a lot of MS20. It’s like 200gsm and great for just general posters. Works on solvent and UV.
If you want me to put you in touch with our rep let me know. Stuff is all good and their prices are excellent.
They have all the really cheap blueback etc that’s like 38p/sqm And a few higher quality poster materials.
We buy some 135gsm silk from canon and it’s like £50 for a 125m roll but I think that paper is just for UV. That’s one of two media’s we buy from canon. Everything else costs an arm and a leg lol
