Proper working environment for Direct-to-garment printers

For the business itself and the people involved, operating direct-to-garment printers under perfect working conditions is essential. What does it mean for a DTG printer? Safety, convenience, temperature and humidity are the basic factors that determine the normal operation of the DTG printers.

First, it is important to avoid narrow and narrow working environments; Such stations often cause mistakes and confusion. Ensuring a comfortable, convenient workstation will help operators walk easily, comprehensively, and help optimize their workflow.

Secondly, As for humidity and temperature conditions, it is important to ensure proper measurements to maximize the performance of the DTG printer. This means that the DTG machine needs room temperature area, Regarding temperature, our DTG printers are best operated at room temperature (10-30°C), and the ideal temperature is about 20°C. Operating the printer at a temperature higher or lower than the mark will result in changes in ink concentration, which may eventually block the ink flow system, leading to the possibility of clogging the print head nozzles. In addition, whether you use a heat press or a tunnel dryer, these machines require high-temperature stability to successfully cure the garment, so the room temperature should be within the recommended range.

Direct garment printers can obtain better-looking DTG prints by controlling the environment and humidity. Keeping the DTG printer at a stable and normal “room temperature” setting will help you get a better-looking finished shirt and reduce ink and maintenance costs. No matter which brand of DTG machine is used, higher humidity helps the ink flow and prevents the print head nozzles from clogging.
It is recommended that humidifiers be used to increase humidity if needed. A dry room increases the chances of a printhead clogging, and may result in excessive (automatic) cleaning of the printhead.
PS: Rooms with windows not only provide fresh air and natural lighting, but also serve as natural humidifiers!

You want to keep the humidity (moisture) level at least between 45% and 60%. Moisture moves from a high concentration area to a low concentration area. This means that if the humidity in the air around the printer is too low, the air will start to suck the moisture contained in the water-based DTG ink into the air. This water removal effect allows the ink to dry faster not only on the shirt but also inside the print head. Because the ink dries faster than expected, it will cause the print head and the machine’s print line to accumulate, and cause unnecessary clogging over time.
Just because you are not clogging the print head nozzles does not necessarily mean that the humidity is at the proper level. Another problem with low humidity is the risk of the printer overheating. Due to the high temperature of DTG machines, they will be automatically cooled by automatic nozzle cleaning and ink flushing. This is similar to the way a computer turns its internal fan on and off. Repeatedly flowing ink through the print head will lower the temperature of the machine, but will waste a lot of ink.

Finally, operating a DTG printer in a cold or hot environment also means that the air filter must be replaced more frequently. Another way for DTG printers to compensate for unsatisfactory conditions is by introducing outside air. Compared with working under standard conditions, this process causes the air filter to be consumed more frequently.

Monitoring the humidity level will save you time and money. By using a hygrometer to monitor the humidity level and using a conventional humidifier as needed, downtime due to increased machine maintenance can be avoided. You will also save the cost of DTG ink for automatic print head cleaning. If you really cannot get the proper humidity, remember that the smaller space, the easier it is to control the atmosphere; therefore, if necessary, try to move your DTG work to a smaller room.

In addition, make sure your direct-to-garment printer from the heat that the press or the dryers release to the atmosphere. Ideally, place the printer opposite the Heat Press or at least at a safe distance away from any curing solution used.

Besides, getting comfortable with your DTG printer by reading the manual and planning regular maintenance checks. Many DTG machines on the market today, like our Sublistar DTG-pro printer, has automated cleaning and maintenance cycles. The two things you will still do manually is agitate (shake) your white ink cartridge and printhead checking. For the white ink cartridges check, you will want to lightly shake the cartridge for about 30 seconds once a day.
A nozzle check is a test print to show you how the individual nozzles on the printhead are working. Clogged nozzles can result from a period of inactivity, a dusty or dry shop atmosphere, or expired inks. It is best to do a print head nozzle check everyday, even when you are not going to print that day. This helps keep the ink flowing so you do not experience printhead issues
