<p>Understanding the evaporation phenomena of ink would be beneficial to realize an inkjet printer that produces a smaller carbon footprint. In this paper, the ink is represented by a ternary mixture of water, PG (propylene glycol), and GL (glycerol). Evaporation of droplets with sizes of 100pL was observed. The experiment result for all mixture compositions shows a similar pattern for evaporation stages. Water has a high evaporation rate in the initial 1∼3 seconds, around 6.2×10-3kg/m2·s, and then proceeds to significantly decrease to 3.9×10-6kg/m2·s as the effect of interaction with the relative humidity in the surrounding environment. Deviation on the empirical calculation is adjusted by reducing the water and PG component as consideration of the evaporation in the nozzle tip during the idle time before ejection, as well as introducing an activity coefficient of 2.5 for PG to accommodate the non-ideality of the mixture. A detailed investigation by a numerical method is expected for future research.</p>
