Looking For Sources Of Information On World Wide Tagging Types

I am looking for information on the tagging types/styles by country. For example US has overall, large block, small block, prephos coated and uncoated paper etc. Using this information I want to compile a DB which would then be added to the stampsmarter.org site. It would be a DB noting characteristics and styles of the tagging. I would like to also include sample images of the tagging under UV as examples are acquired. Some asks for help:

1. Provide any lists of sources available online, I don't want to have to purchase any catalogs.

2. Provide the information in this thread for a country or contact me if in some other form like excel.

3. Since my focus has been on US stamps and tagging, I have limited WW stamps to work from. If anyone has examples they want to donate to the cause please contact me. I will credit the person providing the sample as I have done in the US tagging DB.

I have started to accumulate samples and I gotta say the Australian pink tagging is a favorite already.

Great Britain had many types of tagging. There is fluor and fosfor tagging. There is an extremely good chapter about this in the Deegam Handbook. Unfortùnately, this is not free. The Connoisseur Catalogue may also have something similar, but that part of the catalogue is not available online. The listing of Machins is and it is the best there is. If you go through it, you might find a lot of information as the separate chapters do list the fosfor type used.

Soneham is also quite good, but does not name the fosfor used. It does go into the Wilding period that had fosfors not used for the stamps listed in the previous link.

Many people here will make you believe this is a good site:

Not my cup of tea. IT IS EXTREMELY BASIC for what you are asking. And again, only Machins.

Hong Kong, as far as I am aware is not really available. The Yang and Stanley Gibbons Catalogues list a bit. The Deegam handbook above lists the 1992-1997 defintives and their tagging. However, a 2013 study by Daniel Tangri published in The bookmark Journal (Vol 43, nnr. 4 - Vol. 44, nr. 2) shows there is more to it than even the Deegam Handbook lists. And, of course, there is more than just this set.

Ireland has been using phosphor tagging in different shapes. Not even the Hibernian handbook goes into details. It also has stamps that appear in varieties with or without OBA (fluor tagging). The Hibernian handbook provides detail on that.

Spain and Spanish post offices in Andorra use phosphor. FESOFI has an online dictionary. Fluorescence appears on page 177 and fosforescence on page 179. I am afraid it is not very helpful.

They also have a listing with technical details for each issue of Spain. I am afraid it does not go into detail.

To give some more insight into British tagging:

Wildings come with green (B1), blue (B2) and violet (B3) Letalite phosphor bars. These exist with one or two bars.
The phosphor was applied by photogravure, typography or flexography.
The B3-phosphor was used on commemoratives, that comes in one, wto or even three bars.

In the decimal era, the clay coating of stamps had an optical brightening agent added (fluorescence).
B3-phosphor was used, it was contaminated resulting in Jet phosphor, B2=phosphor made an unplanned re-appearance.
Then came the all-over phosphor and two phosphorised papers. The latter coincided with A-type phosphors that also had a violet afterglow.

Then came Enschedé with Cartax AY, AY2 and AY3 phosphor. then came AB and A2B blue phosphors.
There is a range of vignetting where, primarily, the side bars were "normal" over a certain width but got a progressively coarser screen. This exists with different widths of such vignetting and even with combinations on a single stamp.

As for widths, single bars come in widths of 4-, 4.5-, and 5-mm. Side bars come in widths of 8, 9.5, then 9 and later - with the vignetting - up to 13mm.

There are commemoratives with phosphor leaving part of the printed area uncovered. There are stamps with phosphor bars that have part of the design uncovered. For some time, a year code was hidden this way. On some stamps, like Star Wars stamps issued a few years ago, fluorescent secret printing was added to the design.

Thanks for the input. It is very helpful.
