Country Definitive printing dates, cylinder numbers, (updated)

Royal Mail have confirmed that the printing dates for the 2011 Country Definitives are on the litho plates.

The printings for both England and Scotland ran over two days because they are still produced in reasonable volumes. Cartor currently has no ink-jetting facilities and so to change the print date required them to make a new plate. Wales and Northern Ireland printing was completed in one day so only one set of plates was used.
