Along with the printer itself, companies need floor space to work on the front of it, loading shirts, and room to put a heat press. "You don't want the press too close to the printer. You want to have a few feet of space between the heater and printer. It creates heat and drives out the air, which then will potentially give you issues with, primarily, your white ink," Crocker says. "You want to give yourself enough space between the two to not have the heat press impact the environment around it." Screen printers, who already have access to a tunnel dryer, can forego buying a heat press, but shops that do not should buy a heat press with good pressure on it and make sure it is big enough to accommo- date the largest print size their printer can produce, he adds. DTG-printed shirts that come out of a tunnel dryer will have a different feel than shirts that were placed in a heat press. They will feel more like a screen printed shirt. Heat presses press the ink smooth. Michael Perrelli, marketing manager for Direct Color Systems, says that in addition to the printer and heat press, the direct-to- garment process requires a way to pretreat garments that are going to have a white ink base layer.
