   >This is called "imposition". Printing a book means arranging the pages   
   >(usually) 16 (possibly 32) per side of a very large sheet (and therefore   
   >16 the other side) making a "signature", laid out so that when folded   
   >and folded and folded etc and trimmed, page 1 has page 2 on the back of

   >X00 pages are accounted for. Printed off a reel of paper (confusingly   
   >called a web) nowadays, and slit to sheets before folding. Then stacked   
   >together, the spines abraded and glued (or sewn with thread for fancy   
   >books), then draw on the cover (printed separately on board), glue it,   
   >and give it a final trim.
