Upper Plate B
Like plate A, plate B is composed of Die I clichés and was printed along with Plates A, C and D in a 480-on configuration. Plate B was in use from 23 December 1912 to 26 November 1913. Thus the plate was in use for nearly 12 months, which explains the long list of printing varieties attributed to it.
Plate B was always paired to the lower plate C.
The diagram below shows the positions of individual clichés on a plate of 120 units. The plate comprises left and right panes divided by a central gutter. The positions of the watermarks (POSTAGE, etc.) shown on the diagram are reasonably accurate. Being an upper plate Plate B does not have printer monograms. Note that it does have two anchoring punch holes in the right-hand sheet margin (not shown in the diagram).
Clichés shaded have no known constant printing flaws. Clichés without shading have constant printing flaws, with some flaws having more than one state. The numbering of stamps is conventional.
Constant varieties identified in the Australian Commonwealth Specialist Catalogue (2017) (ACSC) are indicated by the lettering used in the Catalogue. Thus, for example, the cliché at position 1L1 has the letter d, meaning that this is the position of the ACSC-listed flaw 2(B)d. Note that the ACSC identifiers start at d and run to o.
