I compared the cards of the White Lions Series A Rainbow "black dot" deck with the cards of the Blue Edition deck.
I saw no difference between the cards under UV light !?
No fluorescence on the "black dot" cards.
What are the findings of other White Lions fans ?
And what about the cards of the White Lions Series A Rainbow "black lettering on the seal" deck ?
If I remember correctly, there were two decks released with the Series A Rainbow markings on the box.
One - with the marker dot - was a blue backed deck printed with UV-sensitive paper, I think.
The other was the real "rainbow" deck. In the process of switching from printing blue decks to printing red decks, rather than stopping the press, cleaning out the ink well and swapping ink colors, they simply started pushing red ink through the blue ink well, creating a transitional purple color, which varied in shade from blue to red. No two decks were the same shade of purple.
As far as your deck not glowing - are you sure that it's a genuine Rainbow deck? Are you using the right kind of light source? Does the white on the paper glow? Because it's not the ink that would glow - it's the paper.
