Abstract
A system for depositing a substance onto a substrate comprises continuously transporting the substrate in a transport direction while traversing a deposition arrangement across the substrate to deposit the substance in a number of swathes. During such movement the positions of the deposition arrangement and the substrate are controlled with respect to one another such that the swathes complement one another to provide substantially uniform coverage of the substrate. As a result of the defined arrangement, improved substrate speeds can be achieved since there is no need for the substrate to stop at each traverse.
Claims10
A printing arrangement, comprising:
- a substrate transport device for continuously transporting a supply of textile substrate in a transport direction, wherein the substrate transport device comprises an attachment arrangement to prevent shifting of the textile substrate with respect to the substrate transport device during transporting;
- a deposition arrangement comprising one or more carriages, each carriage comprising a plurality of print heads arranged to deposit the same substance, the deposition arrangement being arranged to traverse across the textile substrate for deposition of the substance in one or more diagonal swathes during the movement of the substrate in the transport direction, each swathe having a width corresponding to a width of a print head;
- and
- a control arrangement for synchronising a traverse speed or position of the deposition arrangement to a transport speed or position of the substrate to ensure that swathes complement each other to provide substantially uniform coverage of the substrate by the substance.
