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, like infinite pattern repeat sizes, that cannot be practically achieved with a screen-printing process.One area of textile printing ideally suited to digital printing is the flag and banner market where short runs are common. However, printing of flags and banners presents unique challenges. For example, ink is printed on one side, but must penetrate the fabric so that the image is equally visible on the back (unprinted) side as on the front (printed) side. In addition, while the ink must travel through the fabric, it must not travel laterally causing blurring ...
