Security printing applications

LuminoChem pigments can be incorporated into hidden texts, marks and images and, whilst not visible under normal white light, can be easily verified using ultra-violet light (UV‑A, 365 nm or UV‑C, 254 nm) or a special luminescence detector.
As we can produce pigments of high fluorescent intensity with a very fine particle size LuminoChem pigments are suitable for use in offset, flexo, gravure, screen and intaglio printing techniques. The vividness of our proprietary water soluble and organic solvent soluble fluorescent dyes means they are suitable for use in inkjet printing applications at around 1% concentration. The availability of fine particle size pigments (d90 < 1‑2 µm), allow them to be used in industrial ink jet printers. We produce three types of NIR absorbing materials: solvent soluble, water soluble and insoluble.

  1. Hidden imprints on labels, packaging or a product surface.
  2. Tamper evident seals and security labels
  3. Product authentication
  4. Special applications
