Partnership

Innovating for Advanced Ink Solutions

Kao Collins’ partnership with HP drives innovation in ink formulations, leading to better print quality, reliability, and efficiency for end users. Our collaboration adds to available solutions that address critical needs in industrial inkjet printing, such as the development of SIGMA, a solvent-based ink with a 12-hour decap time and a 24-month shelf life.

Water-Based Inks for HP Printers

Our aqueous inks for HP 45 2.5 technology offer precise, high-resolution printing for industrial applications. Composed of water, dyes or pigments, and humectants, these eco-friendly inks are cost-effective and suitable for uncoated papers, corrugated cardboard, wood, and PVC. With a long shelf life and many non-CMR and PFAS-free formulations, these inks excel in product marking, packaging prototypes, and label printing.
