27 March 2003 - Europe Airmail 40g booklet
Booklet of 4 stamps, and 4 airmail labels, printed by Walsall SP, with cylinder numbers W!(p) - W1 - W1 as shown. When these booklets were printed the phosphor was applied over the paper between the stamps (known as the matrix), which was later removed. Thus any booklets with upward or downward Phosphor shifts would result in short bands at top or bottom, but only on two stamps out of 4.
[Later the 20g booklets were printed with the phosphor intended to be applied on the stamps only as a cost-saving move. Upward or downward Phosphor shifts on those booklets resulted in all four stamps being affected.)
