Introduction

The first definitive printed by Jon Enschedé was in 1979 (8p Rosine) and after that the 18p Bright Green in 1991.
However, these were oddities to make up deficiencies of the contracted Printers at the time.
They helped Royal Mail out in similar circumstances in 2000 with the £1.50-£5.00 high values;
and again in 2005 by printing the 35p Lime Green when DLR was unable to fulfil the contract.

They have also been contracted to produce Miniature Sheets and Prestige Books, but these are outside the scope of this article.

This article concentrates on the period that they were actually contracted to produce stamps for the Royal Mail on a trial basis.
the years between 1993 and 1996.

The sequence of stamps that they produced in those few years could form the basis of a specialised collection in their own right.
To that end, I have produced a chart of the different variations involved in the production which is included below.

Variations

The primary variety within these stamps is the type of security fluor used to identify the postal rate.
These are known as YELLOW and BLUE fluor (and there are variations on that main theme as well - but maybe later). Within these two main fluor colours, there are major considerations to take into account.

YELLOW FLUOR

• Difference in the Fluor type
  • C - Bright Yellow - AY
  • C2- Dull Yellow - AY2
  • C3- Grey-Yellow - AY3
  • Novaglo
• Difference in the Varnish addition
  • Unvarnished
  • 4mm
  • 2mm
• Perf type
  • RE2 (2 holes in margin)
  • RE (1 hole in margin)
• Combinations of the above

BLUE FLUOR

• Difference in the Paper/Gum type

The listing below does not include some of the more esoteric Deegam® entries.
This list has been created entirely from the SG Specialised Catalogue.
Generally speaking, there are "No Dot" and "Dot" versions of each cylinder number to collect except where indicated.

A ready-made PDF version of a detailed listing can be purchased from the Enschedé Machin Definitive Specialised Album.
This will enable you to display your singles as an album.
Alternatively, you could print off this one-page guide to use as a checklist.
