According to co-founder Melinda Farkas, the business, which specialises in water-based inkjet inks for piezo printers, finally produced results it was happy with at the beginning of this year.

The red, green and blue inks glow in the presence of a UV source and are claimed to be invisible under regular daylight.

They can be combined with other print to create effects that change with the illumination or to create graphics that are only visible under UV.

The inks are suitable for a wide range of inkjet-coated substrates, including paper, vinyl and fabric.

Farkas added that, due to the range of substrates, formats and combined print processes, pricing was dependent on each application.
