Security, regulatory compliance, production efficiency are three primary reasons fluorescent ink is used for various applications. The formulation behind this specialty ink is an enhanced, fade-resistant formulation using invisible inks. Fluorescent inks are designed to aid document security and special effects across industries that require a high-quality, high-level of security.

Three Types of Fluorescent Ink

  • UV Fluorescent ink
  • UV Curable Fluorescent ink
  • Infrared (IR) Fluorescent dye
  • Near Infrared (NIR) Fluorescent dye

What are the industries and applications that use fluorescing ink?

Standard Applications

  • Commercial – Branding travel documents, watermarked stationery and office letterheads, cheques (promotional and bank), special certificates, membership cards, research results and formulations, admission and readmission documents and skin markings for zoos, school fairs, public swimming pools, nightclubs, theme parks, conferences, and the like.
  • Industrial – Authentication of documents by quality control engineers, forensic scientists, fire brigade officers, auction houses, and other inspectors.
  • Special Effects or Decorative – Glow-in-the-dark designs, colouring special security fibres, decorating light switches, and glass surfaces.
  • Domestic/Personal – Wills, secret hidden messages, and such.

Media Applications

  • Secure Labels and Stamps – Off-white and translucent
  • Secure Wall Art Vinyl – Tear resistant, fast-drying white media for use with water-based inkjet inks used to make door signs, wall decals, wallpaper, floor graphics, and other secure wall designs.
  • Secure papers (CBS1 & CBS2) – Cheques
  • Receipts and Tickets – Concerts, laundry, luggage tags, museum, parking, banking, etc.
  • Greeting Cards – Medium brightness for specialty designs
  • Bond Papers – Debit cards, bills of laden, phone cards, loyalty cards, key cards, share transfers, sale of property, insurance policies, and applications that require OCR (optical character recognition).
  • Secure Cardboard – Adult kids’ book covers, photo board games, jigsaw puzzles, posters, brochures, etc.

Fluorescent Ink Colours

The colours used in various formulas for fluorescent inks include white, yellow, cyan, magenta, green, light magenta, and light cyan. Some are special orders like green inks.

Printhead Types for Fluorescent Ink

Thermal print head and Drop on Demand are the two types of printers that are widely used when printing with fluorescing inks. They can be used with small and wide format printhead printers.

The Idea Behind Fluorescent Ink

The ultimate goal of using inkjet fluorescent inks is to provide the best, highest quality, printing that abides by the regulations, while allowing ease of reading by the human eye. Faster production relates to higher revenues and more efficient processes.

The elimination of errors is crucial in marking and coding products because these elements are necessary for tracking and tracing batches in case of recalls and for providing proper dating on certain products so consumers know if they are still good for use.

The Future of Fluorescent Ink

The development of new inkjet printer technology, software, and ink formulations is crucial to the accuracy, efficiency, sustainability, security, and productivity across every industry that relies on marking and coding for their products, parts, and packaging.

As fluorescent ink formulas evolve alongside of printer technology, even higher security levels will be achieved. Today’s technology is only the start to newer, better, faster, and more efficient technology that the future holds.
