Abstract

This invention pertains to inkjet printing on fabric and to a pretreatment solution for the fabric that allows high quality printing thereon.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority under 35 U.S.C. §119 from U.S. Provisional Application Ser. No. 60 / 551,275 (filed Mar. 8, 2004), the disclosure of which is incorporated by reference herein for all purposes as if fully set forth.BACKGROUND OF THE INVENTION [0002] This invention pertains to inkjet printing on fabric and to a pretreatment solution for the fabric that allows high quality printing thereon. [0003] Digital printing methods such as inkjet printing are becoming increasingly important for the printing of textiles and offer a number of potential benefits over conventional printing methods such as screen printing. Digital printing eliminates the set up expense associated with screen preparation and can potentially enable cost-effective short run production. Inkjet printing furthermore allows visual effects such as tonal gradients and infinite pattern repeat sizes that cannot be practically achieved with a screen-printing process. ...
