Could textile printing be on the verge of a major breakthrough? For years, conventional processes—known as rotary screen printing—have required a high amount of chemicals to be applied on the textile, involving excessive amounts of water and energy. The process involves a different screen for each colour required in the final design, and a certain amount of print paste needs to be produced to ensure quality throughout the whole lot. This paste remains in the screens, eventually becomes waste and has to be cleaned using water, which then needs to be treated. In total, it is estimated that 90 percent of chemicals used in dyeing operations do not stay on the fibre.
