De La Rue (Dunstable) ATN security self adhesive definitive sheet printings.
Revised Machin definitives counter sheets were issued on 17th February 2009 featuring new security devices. These new sheets use self adhesive paper and come in new sheet sizes.
The stamps will include new security features namely:- Each stamp will carry four 'U' shaped die cuts within the design - one set of two over the value tablet and the other set behind the Queens back. A different self adhesive paper will be used that does not include the water soluble layer.
Additionally, an iridescent ink will be used to print a repeating wavy line text pattern of 'Royal Mail' in background around the Queens head; the head is overprinted also, but with a different pattern.
