<p>[QUOTE="lettow, post: 291477, member: 6986"]The numbering scheme is not so strange if you understand the printing process. When the finished sheets come off the presses, they are stacked on top of each other so that the numbers are in sequence going down through the stack in each position. In other words, if serial number 00000001 is in the upper left corner, the sheet below it will have 00000002 in that same corner. The sheets are then cut down through the stacks so all the finished notes are already in sequence going down through the pile. </p><p><br /></p><p>This is more efficient than having the notes in sequence on each sheet. If this were the case, the cut notes would have to be moved to be in sequence.
