Apologies if this has already been covered, I didn’t find this in any searches.
Does Proofgrade have a recommended expiration/shelf life? My original sample box arrived more than a year ago but I’ve just recently been able to use it. (The closed shipping box has always been stored flat)
On several sheets the masking is flat on one side but wrinkly on the other. I’m sure the GF can cut right through slight wrinkles but has anyone had a problem with that?
I’ve had some experience with this. It’s been more than just the aged masking, the wood finish itself becomes rather ‘pebbly’. At least it’s my belief that this is from long storage. I went through my entire stack of PG, peeled back a portion of a corner and checked each sheet out. Then I marked it accordingly…slightly rough, very rough, etc. right on the bar code sticker. That way I’m not taken by surprise. If it’s pretty bad, I just use it as I would draft board.
I got some with the rough finish straight from the factory. (They had a bad batch or two over the last couple of years.) The older stuff was perfectly fine, and actually in better shape than the bad batches. I’m still using some bits left over from a couple years ago - PRU material. Works fine. Little bit harder to get the masking off.
