How are Solvent Vapours and Volatile Organic Compounds (VOCs) Released from Prints?
When any inkjet printer is operating, VOCs are released as ink vapourises from print media and aerosols are created during the spraying of ink from the print heads. Approximately 80% of solvent based inks become airborne during printing. Also, prints coming out of a printer are not completely dry and emit solvent vapours until drying is complete. In controlling VOC levels in the printing area it is important to take into account that prints will continue to emit VOCs while drying for up to several days. This will be affected by if a dryer is used on the printer, air temperature, humidity and air circulation in the area. Employing an air filtration system to clean the air in the area will assist in keeping the air clear of solvent fumes during and after printing. Environ Air systems are designed to operate continuously to provide the safest work environment.
