Bottle size 30ml 50ml 100ml

Specialist fluorescent stamp ink for discreet marking that becomes much easier to see under suitable UV or blacklight illumination.

Choose the bottle size that suits your expected use: 30ml for lighter use, 50ml for regular use, or 100ml for frequent or higher-volume use.

UV Security Stamp Ink is intended for suitable rubber stamps, compatible stamp pads and appropriate stamping equipment. For the cleanest result, use a clean or dedicated pad; residual coloured ink can affect the UV ink.

The impression is designed to be low-visibility in ordinary light, but complete invisibility cannot be guaranteed. Visibility and fluorescence can vary depending on the material, ambient light, ink quantity and UV source used.

Test unfamiliar surfaces and equipment before relying on the result. A UV torch or lamp is not included unless specifically stated.

Specialist UV security stamp ink

For suitable stamp pads and compatible stamping equipment. The mark is intended to be low-visibility in ordinary light and fluoresce strongly under suitable UV illumination.

Choose bottle size

Select 30ml for lighter use, 50ml for regular use, or 100ml for frequent or higher-volume use.

What to expect from the mark

The same UV ink can look different depending on the material being marked, the amount of ink applied and the light around it.

Normal light

The impression is designed to be much less conspicuous than a conventional coloured mark. Complete invisibility is not guaranteed: a faint tint can remain on some materials or in some lighting.

Under suitable UV light

The fluorescent ink becomes much easier to see when illuminated with a suitable UV or blacklight source. A darker environment can make the effect easier to view.

Fluorescent UV response

Choose the practical bottle size

All three options contain the same specialist UV security ink. Choose the amount that suits how often you expect to replenish a suitable pad.

Size	Suitable for
30ml	Occasional or lighter use
50ml	Regular use
100ml	Frequent or higher-volume use

Set up suitable equipment

UV ink is not automatically suitable for every stamp, cartridge or surface. A clean, dedicated compatible pad gives you the best starting point.

Use a new dry pad

A new dry pad avoids contamination from ordinary coloured ink and gives you a controlled starting point.

Apply ink gradually

Add a small amount evenly, allow it to distribute through the pad and make a test impression. Avoid saturating the pad.

Check under UV light

A suitable UV torch or lamp is needed to check fluorescence. Ambient light and the UV source both affect what you see.

Where UV marking can help

These are practical examples rather than guarantees of suitability or approval for a particular process.

Identification

Security marking, document identification, packaging references, stock and inventory marks.

Access and events

Event admission or re-entry, membership and access applications where the chosen surface and checking process have been tested.

Internal control

Inspection marks, discreet references and internal process identification.

Important: Results can vary by surface. Porous and non-porous materials can behave differently, so test uncertain materials first. UV ink is not guaranteed to be completely invisible in every lighting condition, and a UV torch or lamp is not included unless this product listing specifically says so.
