College is making me miserable

"Corrugation" or "corrugated fiber" is the proper term for the material used to make boxes. when you look at a board used to make boxes, the woven piece inside (flute) is what makes it corrugated. Pre-press has everything to do before the manufacturing process of a box, in this case, proper staging, maintenance, and storage of print plates, and cutting dies.

I wouldn't expect anyone to know that off the top of their head unless they watched some "how it's made" video or worked in the industry. So yes it's normal haha
