A single die proof is one of the last two stages of proofing before final printing of the seals.  This usually consists of a single seal printed alone on a large sheet of paper, sometimes accompanied by a color bar meant  to indicate the proportionate use of basic colors in printing the seal.    

Single die proofs are not intended to be issued as regular accessories of the seal.  These are sparingly provided to principals involved in the printing of the seal.  In addition, in the case of US-made single dies,  some enterprising parties secure these directly from the printer, for sharing with other collectors / dealers.  In other cases,  the single dies, or more specifically   printer’s proofs, were never planned to be issued, and were merely scrounged by collectors from printer’s waste. The single die proofs of 1981, 1982 and 1985 were made in very limited quantities and not everyone was made aware of their availability. 

These materials are listed and described as follows:

 All 1985 proofs were printed by Kyodo Printing Co., Quezon City. 

The foregoing materials were previously unlisted in Green’s Catalog of TB Christmas Seals of the World, and were officially listed only in 1985 – 86. 

It is possible that other single die proofs were made during this period,  which the author is unaware of.  We shall be grateful if collectors or owners of these materials can contact us and give us details and description  thereof.
