Developing Innovative Inks

Our continuous R&D endeavours to collaborate with teams within the industrial printing communities to find common and unique solutions to every possible challenge, adding business value and customer delight by introducing new innovative ink technologies.


Rigorous R&D led to the creation of LUNAJET inks, the first eco-friendly, water-based ink designed for digital printing on plastic flexible film packaging and other non-porous substrates. LUNAJET’s advantages make it the best ink option for industrial printers of food packaging and pharmaceutical packaging.


Our customers are delighted to use SIGMA inks because the long decap time delivers an ink that does not dry quickly. Kao developed this solution when our R&D identified challenges customers faced with short decap times of solvent inks and unproductive downtime on wiping and purging printheads. SIGMA has become the industry’s inkjet ink of choice because it cures fast with deeper blacks and high durability, offering an industry-leading 24-month shelf life with 12-hour decap time.


A revolutionary Funai thermal inkjet cartridge, combined with Kao’ Nexxo solvent ink, now makes marking and coding on curved surfaces possible with double the throw distance. This new offering produces high-resolution expiration dates and lot codes on food and pharmaceutical packaging.
