Have you ever known too much about something? I know just enough about paper to make things difficult in printing the signatures for my latest project.
Paper has grain. It's a bit like a good stake that way. You can cut it along the muscle fibers or across them. Paper has pulp fibers that do the same thing. So, when making a book the grain should run the same direction as the spine.
The difficulty arises when you need 17x11 paper. NO, not 11x17. The second number tells you which direction the grain runs and I need it the 11 length to be the grain.
unfortunately the local prints shops have no idea what I'm talking about...I seem to remember this same problem with the local Joann's store and hook and eye tape...Ignorance isn't bliss, but it makes like a little easier when you don't know enough to care.
