We are now able to show sheets of the new tariff stamps which will be issued on 25 April. (Thanks for the images - you know who you are!)
These are in sheets of 25.
The left margin shows the FSC information against rows 1 and 2, the colour name against row 3, the cylinder number against row 4, and the grid position against row 5. From this we can see that these are printed 12-up, ie 3 columns of 4 rows. (Richard points out that anybody collecting cylinder blocks of 6 from all 12 positions will fork out over £291! Well, if that's what floats your boat, but I can think of better things to spend that amount on. None should be any scarcer than the others and completeness is a disease!!)
In the right margin the bar-code is against row1, the short name against row 2, and dot-matrix date and sheet number against rows 3 and 4.
Printing dates seen so far are:
87p - 08/02/12
£1.28 - 08/02/12
£1.90 - 10/02/12
... which suggests that some printing was probably also done on Thursday 9th February.
