Surface printing, which is much less expensive than recess printing, had
only been intended for the halfpenny green stamp. However, cost savings
during the First World War combined with the halfpenny war tax led to
unexpected demand for slightly higher values and the decision was made to
surface print the other values in this set.
The grey black surface
printed 1½d stamp replaced the 'local' surface print (
1915 King George V Local
Print issue) which were not engraved with sufficient accuracy. Perkins,
Bacon in London produced new 1½d plates at the same time as the new
2d and 3d plates were produced. The colour of the 1½d stamp was
later changed from grey black to orange brown because light cancellations
did not show up on the original stamp.

The surface
print stamps have a different design to the recess and local print stamps.
The surface print stamps have horizontal shading on George V's face and
neck, while the recess and local have diagonal shading. The background on
the surface and local prints has a clear diagonal pattern, while the recess
print stamps have a very fine and complex pattern of alternating arcs with
a criss-cross hatching over the top giving the appearance of almost solid
shading. The local print is very coarsely drawn with rather poorly spaced
diagonal shading lines on the face and neck.
