Around 1984 Tonga introduced progressive proof tabs into the printing process of its stamps.
Instead of having blank gutters, Tonga shows 5 different progressive proof tabs in each sheet of stamps, with each proof tab showing how the stamp looked at a different stage of the printing process.
For instance, proof tab 1 usually shows how the stamp looked when the first color yellow was done.
The proof tab shows the same picture/design as the issued stamps, but is only yellow, and is also missing the words and values.
Proof tab 2 is usually blue, the second color used in the printing process.
Proof tab 1 2 shows what the stamp looked like when both yellow and blue were mixed together, giving the result of a greenish/yellow proof.
Proof tab 3 is usually red which was the third color done.
Proof tab 1 2 3 always shows the stamp in its finished colors after the red is mixed with the blue and yellow – except black is not yet done. This progressive proof looks like the issued stamps but is missing black still.
Many collectors and exhibitors are finding that a strip with the proof tab in the middle is a “different” way to show an item in their collection or exhibit. Very few people thought to collect these strips in this format.
