The 640 on printsheet was the mainstay of Australian production for 4 decades. Starting with the 1938 Zoologicals, it continued, unaltered to the end of the predecimal era.

Four post office sheets were guillotined from the printsheet, each post office sheet contained 2 panes of 80 portrait stamps, 10 rows of 8.

Gutter lines.

Because the interpane gutter was the same size as a stamp (to accommodate the comb perforator), most issues had one or (mostly) two inscribed lines in the central gutter between panes as a security precaution.

Imprints

Until their abandonment, imprints appeared in the lower left corner of EACH pane of 80.
