Longer shelf life and decap means less ink waste, providing an added environmental benefit to using the product. The extended shelf life of Sigma ink, along with its greater-than 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,” explains 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 “Now our partners don’t have to worry about whether or not out-of-date cartridges will work properly, and they can focus on comfortably running production.”
Rogers adds that the shelf life of Sigma ink sets it apart from other TIJ solvent inks.
Sigma ink has proven to be a suitable choice 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.
“Overwhelming feedback about sustainable supply was our primary development focus,” Rogers says.
