Since the mid-90s, research on digital textile printing has become more and more important. This application field offers the possibility of printing photographic-quality images with quick design time. A great advantage, especially for the fashion industry, is the ability to print-on-demand in small quantities down to a lot size of one. According to an analysis by the WTiN Intelligence: Digital Textiles, the worldwide output of digitally printed textiles is growing at an annual rate of approximately 20 per cent. Despite this rapid growth, the proportion of textile production that uses digital printing is only about 3-5 per cent up to now. One difficult criterion for effective industrial digital printing on textiles is the various number of different textile substrates ranging from natural such as cotton, wool or silk to synthetic materials like polyester and blended fabrics. All these fabric types require different types of inks and additional different needs for pre and post-treatment as well as processing. The ink types mainly used in industrial applications are reactive inks for natural fibres and sublimation/disperse inks for digital printing on polyester.
