If you have the Star Wars stamps and don't have an ultra-violet lamp, then you won't be seeing the features on the stamps issued yesterday that are invisible in ordinary light. As far as I know The Drum is the first to reveal this, which isn't in the publicity information that was sent out by Royal Mail to dealers.
The stamps showing the new characters have a fluorsecent representation of the new Film's logo in yellow:
The earlier characters have different emblems in fluorescent white, some have the Alliance Starbird and others the Imperial Crest, as used on the first day of issue postmarks. Some of these are quite difficult to see against the very dark colours of the stamp, suggesting that the fluorescent ink may be below some of the colours.
Thus although there are only 4 obvious cylinder numbers, there are actually 7! Reading upwards:
Black, Cyan, Magenta, Yellow, Phosphor, White Fluor, Yellow Fluor - all C1
There are no fluorescent marks on the miniature sheet, but the same marks are included on the Generic Sheet, and PSB panes.
UPDATE 7 DECEMBER
My thanks to reader Jarvis, and also to Davis
and Alex at Royal Mail Philatelic Enquiries who provided him with this
line-drawing of the fluorescent emblems added to the stamps. The
arrangement shows the 12 stamps in the normal sheets.
