A print substrate transport system comprises a print substrate supply mechanism and a tensioner. The print substrate supply mechanism is configured to advance print substrate to a printing zone in a discontinuous motion. The tensioner is provided downstream of the print printing zone and is configured to guide a path of the print substrate from the printing zone to a post-processing zone, to control tension in the print substrate in the post-processing zone, and to convert the discontinuous motion of the substrate to continuous motion. A print substrate transport method comprises supplying a print substrate to a printing zone in a discontinuous motion, controlling a tension of the print substrate on a path downstream of the printing zone and converting the motion of the substrate from the discontinuous motion to a continuous motion.
