The answer is … when the entire ink reaches its specified cure temperature.
We understand that can be vague. On average, the curing temperature is around 160°C. However the temperature will be dependant on the type of ink you are using., you will need to check the technical data sheets for the specific ink. Specialised inks may have a different curing temperature, for example, a low-temperature ink will actually cure at around 130°C.
Time is also a key factor, depending on the ink. Waterbased ink will need to sit at that temperature for a longer period of time to evaporate the water.
