We use direct to garment digital printing and sublimation.
We have a direct information from Scott Fresener, the founder of http://myt-jet.com and developer of the printer we use
The Fast T-JetŪ 3 is one of U.S. Screen's newest additions to the Fast T-JetŪ line of Inkjet-to-Garment printers. These printers have revolutionized the garment printing industry and the Fast T-JetŪ 3 raises the bar even higher. With 30% faster print speeds and a longer print bed that makes loading and unloading of garments easier, this printer will decrease production time while increasing cost effectiveness.
In 2004 US Screen introduced the garment printing industry to the first Fast T-JetŪ. With the arrival of the Fast T-JetŪ 3,the industry can continue printing the brightest whites on a printer now Made In America.

It is a very robust production machine that prints outstanding images on light and dark shirts!
We have a few direct quotes from www.wikipedia.org that capsulate the definitions of the sublimation processes
Dye sublimation is a printing process that uses the process of sublimation to print full-color images onto a variety of substrates, including paper and canvas print. A small heater is used to vaporize the solid dye material, which then solidifies upon the paper. As this type of printer allows extremely fine control of the primary color ratios it is possible to obtain a good quality picture even with relatively low printer resolution, as compared to other printer types of similar resolution.
Tektronix' "Phaser" computer printers were one of the first examples of the use of the dye sublimation process in a mass-produced printer.
Dye-sublimation can also be used as an indirect printing process. Standard black and white laser printers are capable of printing on plain paper using a special "transfer toner" containing sublimation dyes which can then be permanently heat transferred to T-shirts, hats, mugs, metals, puzzles and other surfaces.
