Why do you need Humidity?
• All DTG machines don't like dry conditions. The ink in the head is more
prone to clog if the air is dry. If you are in a dry area with low humidity, OR,
if you plan to put the machine in a room with very dry heat in the winter,
consider using a humidifier. The ideal conditions are: 45% to 80% relative
humidity, dust free, with no airflow over printer.
