So, I see that my finishers will tell me how many 11x17 pages are used for each finisher. In my case one of the finishers is capable of 20-11x17s and the other is 40- 11x17s.
Of course this is for 20lb paper and paper that is thicker will reduce the amount of 11x17 pages that can be saddle-stitched. Is there a formula for thicker paper? to out what the max booklet would be?
