Invisible UV Porous Marking Ink - Ideal for paper / card / textile

UV Marking Ink

UV Gear's invisible porous ink is specially made for substrates such as paper, cardboard, textiles, currency notes, cloth, etc. The ink appears clear but under a UVA blacklight it will glow bright blue.

This carefully crafted ink is fast drying and can also be used inside inkjet printers - Unfortunately we offer no guarantees for this application and do not offer technical support as all printers are different although clients have had great success.

These inks do not leave a film but may leave a faint visible mark depending on the type of material being treated. Always check a small amount to make sure you get the desired result. Please call or email if you need any further advice.
