## Overview

Opticz Industrial Invisible Blue UV Blacklight Reactive Security Ink is a 4-ounce solvent-based ink that remains invisible under normal light but fluoresces bright blue under UV blacklight.

Ideal for covert security marking and authentication, this trusted USA-made ink is non-toxic when used as directed but not safe for skin or tattoo applications.

## Description

This is that hard to find UV Blacklight Reactive Invisible Ink for box marking, document marking, and other unique security applications. Only visible under black light. Ink is water resistant and very difficult to remove. Best viewed in dark or shaded area. Opticz Blacklight Reactive Invisible Printing Inks are suitable for paper marking as well as non-porous material marking. This ink is invisible/colorless and will glow bright blue under UV blacklight. This ink should NOT be used for readmission (e.g. on skin use). Industrial application only. Can be used on: aluminum, cardboard, ABS, acrylic, rubber, cellulose, acetate, formica, nylon, polystyrene, Polyethylene and most other materials and porous surfaces. Ink is solvent based so a little goes a very long way! Ink is formulated to fluoresce brightly under long wave ultraviolet light only. They do NOT glow in the dark! Fast drying and non-transferable. Ideal for applying onto an already printed surface. Please note if applied to a bright white surface that is also UV reactive, this will make the ink hard to see because bright white will glow blue when under a blacklight. Off white to medium color tones yield ther best results. Avoid eye contact and excessive inhalation. Do not ingest. KEEP OUT OF THE REACH OF CHILDREN.

## Questions & Answers

**Q: Can i use it in rubber stamping pad, or it will evaporate?**
A: Yes on both. It is rubber stamp friendly, but being an alcohol based ink it does evaporate quickly. A saturated stamp sitting out more than a minute or so will dry out. Use immediately when needed and it’s no problem

**Q: Are there any recommended empty / refillable marker types to use?**
A: https://www.amazon.com/dp/B07BPXZ9HQ?ref=myi_title_dp

Our marker version of this product. Non refillable.

**Q: What wave length blacklight does this work with?**
A: 365-395nm LED or fluorescent fixture/bulb(s) are fine

**Q: Can this be used in a pump spray bottle, to cover multiple metal items?**
A: Yes. The ink is an isopropyl alcohol base and is very thin. About the same consistency as water. It could work through a spray pump just fine.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Stuff. Good Value
*by O***Y on April 7, 2025*

Works well. Note, the package says not for use on skin. The company sells skin-safe ink too, so make sure you order what you need. I was going to simply use a fingerprint. Instead I used a rubber stamp.I used this to put a security mark on documents. Much faster and cheaper than using a UV marker that tends to dry out quickly.

### ⭐⭐⭐⭐⭐ Works just as advertised!
*by S***E on January 23, 2019*

we used this to mark the back of playing cards with painted numbers. Worked perfectly.

### ⭐⭐⭐⭐ works nice!
*by M***S on November 29, 2018*

It works nicely, however its alcohol based so it can dry up if not covered on the stamp pad.
