Ultra-thin UV ink for printers 

Ultra-liquid invisible fluorescent ink
The refillable print cartridge filled with invisible fluorescent ink offers a simple and cost-effective solution for producing invisible prints using a standard inkjet printer.
This water-based technical ink is completely transparent in daylight and only reveals the marking when exposed to a suitable ultraviolet light source.

  
Applications
Thanks to this technology, it is possible to print confidential information without altering the appearance of the document.
► Serial numbers, internal codes, signatures, manufacturing marks, invisible logos or authentication features remain completely hidden until checked under a UV lamp.

  
Compatibility
This special ink has been specifically developed for refilling refillable cartridges for inkjet printers.
Its extremely low viscosity ensures optimal flow through the printer’s ink supply system whilst guaranteeing excellent print stability.

ArcoIris® hydro formula
The formulation is compatible with the main ‘inkjet’ technologies:

  
Characteristics
The ink has excellent surface tension, an essential characteristic for forming uniform droplets and producing a crisp print.
It dries quickly after printing, minimising the risk of smudging whilst ensuring very good adhesion to a variety of substrates*.

  
Fluorescence*
The liquid remains completely colourless when viewed under standard lighting. When illuminated by a UV lamp, it produces a particularly intense blue fluorescence. To achieve maximum light output, the use of a 365 nm UV lamp is strongly recommended.
This phenomenon is known as invisible fluorescence. Unlike phosphorescence, which continues to emit light after the light source has been switched off, fluorescence is only visible whilst exposed to ultraviolet light.
As soon as the lamp is switched off, the marking immediately becomes invisible again.

The product
The 60 ml bottle is sufficient to fill several refillable cartridges, depending on their capacity. This solution offers a particularly low cost of use for businesses that regularly produce security prints or confidential markings.
The water-based formulation also has the advantage of not being classified as a hazardous product under normal conditions of use.
It contains no harsh solvents and is easier to handle than many industrial technical inks.

Applications
The range of applications is very wide: this invisible fluorescent ink is used for anti-counterfeiting, discreet product identification, quality control, logistics tracking, secure documents, event tickets, certificates, packaging, technical labels, internal audits, as well as artistic creations utilising effects revealed under black light.
Designed for discerning users, this ink for printer cartridges combines smooth flow, compatibility, safety in use and luminous efficiency.
It transforms a standard inkjet printer into a fully-fledged invisible printing system suitable for both professional applications and creative projects.
