What is it about?
Disperse dyes are available which have been selected for easy surface clearing to maximize fastness properties. This study applies these dyes to alkali pre-printed polyester fabrics - the alkali printed areas will not dye leaving a white printed design. If a disperse dye which is unaffected by alkali is included in the alkali-containing ink then only this colour is seen in the printed area following subsequent over-dyeing with the alkali sensitive dyes.

Why is it important?
The above 'resist' and 'illuminated resist' styles are used by the conventional screen printing industry - the advent of ink-jet printing as a textile printing method requires the flexibility of this style. The main advantage is the production of high definition white prints on dark backgrounds.
Perspectives
We have already published on novel methods of producing resist/illuminated resists when ink-jet printing cotton with reactive dyes. this publication squares the circle by introducing the concept to polyester fabrics. Discharge printing with reducing agents is often used by the industry to achieve similar design effects but the procedure can be torturous compared to the simple ink-jet procedures out-lined in these papers.
