Ink-Jet Printing Cotton with Cationic Reactive Dye Based Inks

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

Color gamut reduction techniques for printing with custom inks

Printing with custom inks is of interest both for artistic purposes and for printing security documents such as banknotes. However, in order to create designs with only a few custom inks, a general purpose high-quality gamut reduction technique is needed. Most existing gamut mapping techniques map an input gamut such as the gamut of a CRT display into the gamut of an output device such as a CMY...

Polymerization of Vegetable Oils and Their Uses in Printing Inks

Materials. Alkali-refined soybean oil was obtained from Riceland Foods (Stuttgart, AR) and Archer Daniels Midland (Decatur, IL). Alkali-refined canola and cottonseed oils were purchased from Bunge Oil (Bradley. IL). Alkalirefined sunflower oil was obtained from Archer Daniels Midland. Alkali-refined safflower oil was obtained from Pacific Anchor Chemical Co. (Cumberland, RI). Polystyrene standa...

Multilevel halftoning applied to achromatic inks in multi-channel printing

Microfluidic Printheads for Multimaterial 3D Printing of Viscoelastic Inks.

Multimaterial 3D printing using microfluidic printheads specifically designed for seamless switching between two visco-elastic materials "on-the-fly" during fabrication is demonstrated. This approach opens new avenues for the digital assembly of functional matter with controlled compositional and property gradients at the microscale.
