For my first post I thought I would make it a bit interesting. One of the areas I have found very little published information on is the same stamp printed with ink that varies in color under long wave UV (LW UV). Numerous modern issues are printed with ink that is non-reactive or reactive (luminescent) to varying degrees under LW UV. In some cases the effect is subtle, but for most it is fairly dramatic.

All that is required to find these varieties is to view the stamp under LW UV (blacklight). I use an 18" fluorescent blacklight tube found at most home improvement stores or ordered online. I also use an inexpensive lamp fixture that takes 18 tubes. For me the fluorescent tubes work the best versus LED or incandescent blacklights. Working with another avid collector we have cataloged approximately150 modern varieties of this type. This adds a whole new avenue for collecting. Below are a few examples.

Below is the list we have identified so far.

Canada Post did a lot of research for paper varieties and tagging back in the 60's to 70's! There are many paper varieties as well as tagging too, Ottawa OP2, OP4, General Tagging, Winnipeg tagging in right bars, left bars, two bar, centre bar wide centre bar narrow. The Cameo definitives have a number, but the Centennial definitives take the cake as far as paper varieties go & tagging.

It'll keep you busy for some time!

Hello Mark (mstocky2 ), great leading post and I must admit, I was intrigued.

As a collector of Plate Numbered Coils (PNCs) of the USA Transportation Coils and looking at my own collection, I was surprised to see and confirm the luminescent inks used - specifically on Scott n.º 2452, the Circus Wagon. Additional details can be found on the Stamp Smarter website - Designs of the 1981 Series - The Transportation Coils

Thanks for generating the awareness...

Happy collecting!

I think they wanted to give philatelists "Hell" !!
I am only aware of the Canadians' ones - for some it is a pastime (hobby) or a specialty ?

Don't know why this is the case, but it makes for interesting collecting. Here is a few more for you viewing pleasure.

This next one is pretty interesting. Some of the flowering trees issues were printed with a clear varnish over the flowers. The varnish contains optical brighteners that glow a bright white under long wave UV. The flowers on all five issues in a pane will either have this or not. The white is very vivid and the stamps are quite beautiful under LW UV. I am not aware of why this was done.

Nope, lamp off and no luminescent ink varieties here,

USA 1¢ Tiffany Lamp Coils (Scott n.º 3758)

Although not in the current listing shared by Mark (mstocky2 ), the Tiffany Lamp Coil Stamps also can be found with the luminescent ink.

If anyone has the variety and can show, please do so...

Happy collecting!

Thanks for showing Mark (mstocky2 ); it is appreciated :-)
As I build out my own collection of the Tiffany Stamp issue with back numbers, a strip of the luminescent variety is on the list...

Not having both versions of the 1¢ Tiffany Lamp to compare, it is difficult to decide just what I have. It is a dark stamp to begin with, which doesn't help me in the least! But the 4 I have look to be non-luminescent.

I heard somewhere that the luminescent ink is sound activated Pete (brightonpete ) and you need to clap one to twice in order to make the lamp appear to be on ;-)

Seriously, given the few examples I have and the ones shown earlier by Mark (mstocky2 ), the luminescent ink under the lamp is quite striking and there no doubt when you see it, to know that's one.
Thanks for looking and these varieties are certainly something to keep one's eyes open for...
