our products

Today NANUM is known worldwide for the production of Magnetic Dispersions and water-based MICR Inks, made from ceramic, inert and non-toxic nanoparticles, with state-of-the-art and innovative technology in the security printing market.
MICR inks for inkjet printers are widely applied in bank checks, currency, documents as passports, visas, id cards and other security documents. Our products have outstanding performance in application and have unique properties:
  • High product stability, obtained from the innovative functionalization process;
  • Homogeneous size distribution of nanoparticles;
  • Excellent magnetic property when exposed to a magnetic field.
We have five product lines focusing on the security printing market, for various applications:
  • Magnetic Dispersion
  • MICR Inkjet Ink (bulk)
  • MICR Inkjet Ink Cartridges
  • Cleaning Flush
  • Invisible Ink
Products in development
NANUM has developed a new line of inks, known as Invisible Inks. They are made from pigments that under normal lighting conditions are invisible, however under the incidence of UV light reveal the hidden printing on paper and highlight bright colors.
NANUM has advanced in the research of new nanoparticles of metal oxides, such as nano catalysts, nano composites and new dispersions, capable of optimizing processes and improving the performance of different products.
NANUM is developing innovative lines of products for many applications, focused on offering solutions to different demands in the market. We are open to develop new products that are in synergy with our business model. Please contact us and inform your needs.
