printing process, coupled with the inexperience of the
printer, produced an issue of stamps with many plate position
dependent differences. As described in Production
of the Issue, the transfer stones used in making the
printing plates had three images in the case of the ½d
and 2½d and six images in the case of the 1d, 2d, 5d, 6d,
and 1/-. Each position on the transfer stone can be
identified by the presence of constant, position-dependent
flaws. Further, even lesser flaws, which are produced as part
of the lithographic printing process, make it possible to
identify the absolute plate position of most stamps.
The links below
contain descriptions of the major flaws that permit the
transfer stone positions of stamps to be identified. The
descriptions are taken from Gisburn. Nearly all type
charactristics are shown here - many thanks to "Aore" for his help!
