<p>[QUOTE=&quot;Numbers, post: 2803949, member: 11668&quot;]Yes.</p><p><br /></p><p>The new SOI presses, used for the 50-subject $1 notes, hold three plates at a time, which keep cycling around the press.&nbsp; The three plates mounted on a press may or may not have consecutive numbers, and may or may not be mounted on the press in numerical order.&nbsp; In particular, if one plate wears out or becomes damaged, it&#039;ll often be replaced while the other two remain in use--so all sorts of different combinations of plates are possible.</p><p><br /></p><p>The backs of the notes are printed first, then the faces.&nbsp; This means that if you get a stack of consecutive notes, the back plates most often cycle *backwards*.&nbsp; Let&#039;s say the BEP put back plates 6, 7, 8 on a press in that order; then a stack of consecutive notes would show back plates 8, 7, 6, 8, 7, 6, 8, ...&nbsp; (Of course, if plate 7 then needed replacing, they might very well replace it with plate 15 or something, and keep running the press with plates 6, 15, 8 installed.)</p><p><br /></p><p>Also, the sheets are inspected after the back printing, and again after the face printing; each time, defective sheets are removed.&nbsp; That means that the cycle of plate numbers may &quot;skip&quot; occasionally, when a bad sheet is pulled out.&nbsp; (These inspections take place before the serial numbers are even printed, so no star notes are involved here--the bad sheets are just removed and destroyed.)&nbsp; So in general, there&#039;s no way to predict the plate number of one note by looking at the plate number of the next consecutive note.[/QUOTE]</p><p><br /></p>
