Sigma ink now offers two-year shelf life

Sigma ink now offers two-year shelf life with added environmental benefit

Kao Collins has announced that ongoing testing of its new Sigma solvent ink proved the product now offers a two-year shelf life, which is, according to the company, four times more than competitors’ inks.

Longer shelf life contributes to less ink waste, providing an added environmental benefit. Moreover, its over 12-hour decap time, offers a sustainable alternative for printers who rely on solvent ink for HP 45a industrial printing systems.

‘We heard from OEMs and customers who were tired of having to worry about expired cartridges because of their inks’ limited shelf life,’ said Chris Rogers, vice president of Kao Collins. ‘Now our partners don’t have to worry about whether or not out-of-date cartridges will work properly, and they can focus on comfortably running production. Overwhelming feedback about sustainable supply was our primary development focus.’

The newly proven shelf life of Sigma ink sets it apart from all other TIJ solvent inks. It is an ideal inkjet printing technology for mailing and addressing industries, along with product coding. The ink adheres to more substrates, including films such as BOPP, PE, PET and PP, foils, a variety of label materials, some metals, and many other non-porous materials.
