Tagging - phosphor coating on stamps used to activate automatic mail-handling equipment. This may be lines, bars, part of the design area or the entire stamp surface. Some stamps are issued both with and without tagging.
TAGGING: A chemical substance applied to a stamp which activates automative cancellation machines.
TONGS: Metal tweezer-like implements used to handle stamps.
TOPICALS: Stamps which all have a common theme, such as animals, flowers, etc.
Tagging. The impregnation of phosphorescent dies into the paper used to print a stamp. When "read" by special Ultra Violet machines during mail processing, the phosphors determine the face value of the stamp(s) being used to pay postage.
Tagging
Tagging is a chemical substance used to coat a stamp (or as a component of its ink or paper) that reacts to Ultra-Violet light by glowing. The purpose is to make stamps easier for automated facer-cancellers and sorting machines to detect.
Tagging - Adding phosphor material to stamps in order to activate automated mail-handling equipment.
TC or TCP - Trial Color Proof.
Teeth - The protruding points along the outer edge of a separated, perforated stamp.
Tagging
The process of adding a taggant material to the paper or as a separate application in the printing to produce a phosphorescent or luminescent reaction under ultraviolet light.

Tagging - Addition of some material to a postage stamp or postal item to trigger a sensing device in an automatic letter-facing machine. By far the most common tagging is an ink containing a phosphor, or a phosphor contained in or on the paper.
No tagging was used for the 10,000,000 production run, presumably because of the stamp's intended purpose for use on overseas parcels, which are not scanned by phosphor sensing machines.
Postal stamp phosphor tagging - this was first used in Britain as a modern stamp printing process to distinguish first and second class mail.
