The 1938 issue continued to use the old value plates, in use since 1909 (with some exceptions) but a new intaglio (recess printed) frame printing method and a new frame design were introduced. The imprint was in the colour of the frame.
The frame plate was printed 240 units at a time, with the upper sheet of 120 identifed by the absence of a dot under the imprint, the lower sheet of 120 has a dot under the imprint.
Not all values appeared with each type of imprint because the upper and lower frame sheets of 120 had different values printed at the same time. In some situations, a single sheet of 120 would have been printed on its own.
The ½d value saw just one setting with no dot

The 1d value saw both settings, without dot and with dot. Just the lower sheet, with dot, is shown here

The 2d value also appears with both settings, just the 'no dot' (upper sheet) setting is shown here

The 3d value appeared only in the 'no dot' (upper sheet) setting but I don't have one to show you.
The 4d value saw both settings (just the 'no dot' setting shown here)

The 6d also appeared in each setting, each shown here


Finally, the 1s value appeared in just a single setting, without the dot.

The ones I have not shown are the ones I don't have. If anyone knows of any I have not shown, I'd be grateful if you would let me know.
When John Ash's names was removed from the frame plate, the same plates continued to be used but with the reference to John Ash removed and replaced with 'PRINTED BY THE AUTHORITY OF / THE GOVERNMENT OF THE COMMONWEALTH OF AUSTRALIA'.
The 'O' looks like this '0'. A later version has the 'O' looking like this 'O'. The former type is continued use of modified Ash plates.
