Novel digital carpet printing using acid ink

Because of the extensive amount of waste water that is discharged during its processes, conventional carpet printing is a big polluting industry. In this paper, we propose a new digital carpet printing method based on traditional textile-printing technology. Our method aims to remove limitations in carpet design and eliminate industry pollution. A series of measures are performed to raise the permeability of acid inks. In addition, a new ink control method is employed to compensate for penetrated color inks. This results in carpet production processes that not only take advantage of digital textile printers, but also satisfy the requirements of carpet production.
