DAE check the grain direction before gluing up? Watched a guy in Columbus ruin 3 signatures in 20 minutes
I was at the Ohio Bookbinders meetup in Columbus two weeks ago and this guy next to me was folding signatures for a coptic binding demo. Nice paper too, Stonehenge, probably $8 a sheet. Thing is, he never once checked the grain before folding, just grabbed sheets and went to town. Me and another lady watched him fold, score, and press all three signatures, and every single one cracked along the spine when he opened them. The grain was running crosswise and the fibers just split right there. He kept saying the paper was bad and blamed the shop he bought it from. Finally the lady running the demo walked over, picked up a scrap, did the wet finger test, and showed him the curl went the wrong way. He'd been binding for a bit too apparently, not brand new. I check grain on everything now, even cheap copy paper for practice books. Any of you ever catch a whole batch of paper cut wrong from the mill, or is it pretty rare once you know what to look for?
