With this printer ink, you can print invisible with your refillable ink jet printer. The print is visible through the use of black light. (Best results with blacklight light at 365nm) Also possible by using UV at 395nm, however, the print visible colors are less attractive.
Use this ink, for example on security documents, labels and tickets. Also suitable as theft protection, personal images and secret messages.
Use the invisible colors as follow:
UV Black ink - replaces black
UV inks Cyan - replacing Cyan
UV ink Magenta - replaces magenta
UV ink Yellow - replaces yellow
The UV inks are invisible under normal daylight. The prints are only visible when using UV / blacklight light.
This set consists of 4 colors, white 10 ml, cyan 10 ml, magenta 10 ml and yellow 10 ml. Overall this set contains 40 ml. These are fairly small bottles to keep it reasonably affordable ink. As an option you can also choose for the set of 50 ml bottles.
The best results will be on paper that doesn't light up with UV, white paper lights up already under blacklight this leaves the printing less noticeable. Preferably for example, yellow or blue not light up paper. the effect will be the best.
Do you have an Epson (photo) printer with 6 colors choose the set with six color you will get an even better result.
