Fish Tank Computer Wallpaper

is there a way to make blacklight photos with my printer?

I have a large salt water fish tank, and I would like to put a black-light glow poster as the background using a few of the designer fractals I have found that can be used as desktop wallpaper. But I would love it to be glow black light since I would like to use a black-light at night in the tank. Can this be done? Have you tried it? Is there actual pigment someplace that would work in my computer printer?
to signman…that’s interesting…so I could use an empty print cartridge and fill it with laundry whitener (could you name one?) I have an old printer and it would be worth experimenting with…

‘blacklight’ posters are printed with a chemical additive to the inks/paint the reacts to true blacklight (ultraviolet rays). Flourescent inks used on posters will appear ‘brighter’ with a ‘purple light bulb’ that screws into any light socket-but that is NOT true ultraviolet-that’s just a purple colored light bulb. Only Flourescent light tubes emit enough ultraviolet spectrum to cause the reaction. A ‘true’ blacklight will hardly light up an area-but the ultraviolet rays will reach all the way to the end of a large room. Anything with ‘reactive’ chemicals will appear to glow. Toothpaste, some laundry detergents, additives to white shirts-all will ‘glow’ because they react to the ultraviolet rays.
As far as I know-there is nothing you can get for a household printer that is reactive to ultraviolet.
