If it is folded so that there is one smooth folded edge on the side (for inserting into an envelope) it is a "map fold" usually on a 22" X 26" sheet of paper. However if more than one fold is on both sides it is an accordian fold or some bastard variation of an accordian fold. Check with your printer before you attempt something like this as not many have the bindery equipment to handle this.

Subject: folded brochure
Anyone here know what the correct printing term is for a brochure that is folded up like a map, say into 16 or 24 sections (that is, counting both sides of the sheet)?
Thanks,
Rick
