Abstract: A method and apparatus for printing images on a high volume of printable substrates such as garments is disclosed. The apparatus comprises an inkjet printer, a conveyor system, heat presses and beds. The beds are trays with garment attachments such as platens for holding multiple garments in place during printing. In the preferred embodiment, the method first involves loading garments onto the beds and platens. The beds then travel along the conveyor system which includes one or more conveyor tables and optional heat presses. The beds are preferable placed under a heat press for pre-pressing the garments. Then the conveyor system facilitates the transfer of the beds to a high volume inkjet printer, where both an underbase and an image can be printed on each garment. After printing images on the garments, the beds are transferred again to the conveyor system and optionally delivered to another heat press to cure the image. Finally, the garments are unloaded from the beds and new un-printed garments are loaded.
