Ron,, you got a UV light? Get a 'standard', a old piece of paper [pre 50] from a old book, or old document, and a new sheet . Test both,. You will see the new sheet will glow big time!,,,,,then test your book..
2 things,, Don't buy a 'Black Light',,,you want a Ultraviolet light , UV.
And,,it only works in white...
