An improved, large-format digital inkjet print engine that includes a group of co-operating print engine subassemblies that embody various novel elements that both discreetly and cumulatively advance the current art. The group of subassemblies and sensors cooperate to produce high quality graphic images using a plurality of different colors of ink and different types of print media at speeds several times faster than similar conventional inkjet printers. In addition, the use of cooperating elements permit the manufacture of complex, large-format digital color inkjet print engines that are less expensive to fabricated, operated, and serviced. The present invention finds use in large-format digital color printing and imaging, where successful repeatable printing requires precise placement of droplets of ink, toner or other marking material on a print medium such as paper, vinyl, film, or similar substrate.

The method and apparatus of the present invention increases the precision for drying diverse textile printing substrates during printing operation while ink is emitted from an ink jet print head to form patterns upon the textile substrate. The present invention addresses several long-standing obstacles to high quality printed textile output including media handling from a powered media supply roll, through a cross-web tensioning area, an idler pulley, then over a full-web media advance grit roller, through a printing zone, over an idler pulley, through a forced heating zone (preferably dual-sided), then over another idler pulley, and finally onto a take-up spool which is biased against the force created by the powered media supply spool. The print engine of the present invention utilizes an open-web printing zone, dual forced air heating of both the underside and the upper side of freshly printed media, and a continuously biased tension in the axial web directions and cross-web directions. The media is preferably loaded in a center-justified orientation and the engine is tolerant of traditionally produced textile media rolls, cores, and fabric varieties.
