I probably shouldn't say this because I work in the lab, but the cutter in the lab should be used with extreme caution. I was there tonight and cut my pages only to realize that it cuts at a slant. Not sure what I did wrong, but the top of my text block is wider by about 1/8 of an inch, maybe even more, than the bottom of my book. Praise be that this is just a draft. For my final, I'm going to get the pages professionally trimmed. Good luck!
