In 12s, in which a 4-leaf off-cut is quired into the remaining 8 leaves, the corresponding practice is to sign leaves 1 and 5, likewise signing as "A2" etc., or sometimes 1,2 and 5 (as A1, A2, A3).</div><div class="gmail_default" style="font-family:georgia,serif;font-size:small"><br></div><div class="gmail_default" style="font-family:georgia,serif;font-size:small">In these examples, a full collation is routinely followed by a signing statement (using "$" to mean "any signature"); the patterns here are common ones:</div><div class="gmail_default" style="font-family:georgia,serif;font-size:small"><br></div><div class="gmail_default" style="font-family:georgia,serif;font-size:small">Collation: [A]⁴ b1[=Y12] B-X¹² Y¹²(-Y12) [$1,2,5 signed; signing $5 as
