  • Patent number: 11230118
    Abstract: In one embodiment, a high-speed, closed-loop fabric printer comprises a plurality of consecutive stations that can be managed by a single operator. In particular, shirts or other fabric garments may be individually loaded and secured on a pallet by an operator, and the loaded pallets may then cycle through a plurality of unmanned stations positioned along a contiguous path (e.g., oval). The stations may be configured for pretreating the fabric surface, drying and pressing the pretreated fabric with heat, and then inkjet printing a selected image, among others. In this manner, a “wet-to-dry-to-wet” direct to garment (DTG) printing process may thus be achieved, along with optimal controls for maximum adaptability. Furthermore, due to the closed-loop design, a recently printed fabric product returns to the operator to be unloaded at the position in which a new unprinted fabric is loaded, allowing for increased throughput and minimal operator requirements.
