it would look very suspicious if you had a bunch of blank pages everywhere

Type something else on every other line and make it look double spaced.

Very cool instructions indeed,however i have tried it but the result were not good wit red uv ink. My solution was to purchase red uv invisible ink for printers from uvstuff.com and fill my own cartridge.For those interested above you can print any color in invisible using the main 4 color uv inks with a printer cartridges .Only by mixing those colors you will be able to print all others.

You don't need to buy all those invivible ink pens to get the invisible ink. There is a brand of fountain pen ink called Noodler's Ink, which sells invisible UV ink, avalible from many online distributors.

 Will it ruin the insides of the ink-jets? I was thinking about using 2 different black cartridges

awesome instuctable..also you can use lemon juice and when you want to see it hold i about 3-7 inches away from the flame. make sure the paper doesnt burn though..

oo great idea, but you also wouldnt be able to print in any other colors besides the primary colors other than yellow because the printer mixes the colors to form other colors. it would just be easier to replace the black ink and only print in black.

or have two different black cartages

author
dombeef (author)pyelitegamerro762008-11-08

no wait use a different color black light ink!

author
Trebawa (author)pyelitegamerro762008-08-23

My thoughts exactly. In addition, my printer has an option to print whatever you send it in grayscale only using the black cartridge, so one could print solely in invisible.

very good videography! and song selection....sounds like a cool trick..

author
Weissensteinburg (author)2008-04-23

Wow! Just hope no one tries to use the seemingly blank paper afterwards =]

author

even if they did use the paper, theoretically the invisible ink would still show up and be legible when viewed under a black lamp, b/c the filtering effect of the glass would block the "regular" ink.

author

Good point.

author
Jeebiss (author)residentevil52008-10-11

Any cartridge that uses a sponge reservoir.

genius.

this would be a cool project, unfortunately ink cartridges are so expensive... it cost as much money buying ink cartridges as putting gas in the car

Very interesting.

joe57005 (author)2008-04-26

good one. that will actually be better than just drawing with the invisible pens, since they may leave indentations in the paper.

foobear (author)2008-04-24

Excellent!

I think this is just about the coolest Instructable I have seen so far. Awesome. How hard is it to take out the ink from the pens, do you have some sort of technique?

author
LinuxH4x0r (author)2008-04-23
