Direct-to-garment (DTG) printers can get better looking DTG prints by controlling the environment and humidity. Keeping your printer in stable and normal “room temperature” settings will help you get better looking finished shirts and lower your ink and maintenance costs. A higher level of humidity helps with ink flow and prevents print head nozzles from clogging no matter which brand of DTG machine. Humidity (moisture) level at least at 45% all the way up to 80%. Moisture moves from areas of high concentration to areas of lower concentration. This means that if the humidity in the air around your printer is too low, the air will start pulling the moisture contained in your water-based DTG ink into the air. This water removal causes the ink to dry quicker not only on the shirt but inside the printhead too. Since the ink is drying quicker than intended it can cause a buildup inside the print head and machine print lines, leading to unwanted clogs over time.

Monitoring the humidity level will save you time and money. By using a hygrometer to monitor humidity levels and a regular humidifier as needed you avoid downtime caused by increased machine maintenance.
