Invisible fluo inks for printing
Invisible fluo inks (glowing under UV) are inks transparent in the daylight, which additional fluorescent colour is visible under UV light (in wavelengths from 365 nm to 280 nm).
They are used mainly for security from forgery of documents, vouchers, lottery coupons, lunch cards, labels and packaging.
They are also used during the production process, they enable marking of products invisible to the end customer, which is helpful in production management.
The inks are available in standard colours glowing under UV: yellow, blue, green, red and orange (for other colours – please contact us).
On our Customer’s request, we adjust the intensity of glowing under UV light. It is also possible for us to prepare an ink which has UV colours glowing in two ranges of UV light.
