Novel pigment colorant sets have been developed using Cabot's proprietary surface treatment technology. The new technology involves treatment of the pigment surface with reactive precursors. Subsequent secondary and tertiary reactions with pre-formed polymers and oligomers yields materials with unique physico-chemical properties. The combination of unique chemistries and advanced purification methods lead to well characterized pure pigments, void of free polymers and impurities.

These methods allow customization of the pigment surface that can create new levels of pigment performance required for demanding digital printing applications. This includes enhanced formulation flexibility, new levels of colloidal stability, tuned colorant-media interactions, and increased permanence. A discussion of the various chemical approaches and material performance properties will be presented.

  • For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
