Abstract: A digital pretreatment system and method for preparing textile or garment substrates for printing are disclosed. The system includes a digital printer having at least one inkjet print head fluidly coupled to a reservoir of pretreatment solution and configured to receive a digital artwork file. The artwork file represents a silhouette of an image area to be printed and may be transmitted via removable media, a network connection, or an external computing device. An image processor, which may be integrated with or external to the printer, converts the artwork file into a pretreatment control image, such as a grayscale or dithered monochrome image, to control spatially varying application of pretreatment solution. The system can expand the silhouette outline and generate gradient transition zones to improve registration and reduce visible pretreat artifacts.

Abstract: Disclosed is a carriage for a direct to garment inkjet printing machine. The machine has a frame having a leading edge, a trailing edge, and a pair of opposed lateral edges. A first row of slots is positioned on the leading edge and a second row of slots is positioned on the trailing edge. The second row of slots is spaced from the first row of slots by a gelling gap. A shelf on the frame supports tanks of white ink and tanks of color ink and a first plurality of tubing connects a tank of white ink positioned on the shelf with a print head in the first row of slots. A second plurality of tubing is for connecting a tank of color ink positioned on the shelf with a print head in the second row of slots. A pair of side heaters attached to opposed lateral edges of the first frame.

Abstract: A method of printing ink on a textile including providing a source of white ink; providing a first print head connected to the source of white ink and mounted for reciprocating translational movement through a printing zone; providing a heating source; moving the first print head through the printing zone to apply white ink to a substrate positioned in the printing zone; and moving the heating source through the printing zone to heat the white ink on the substrate to cause gelling of the white ink.
