When using water-based sublimation inks ,Some things to be aware of it

When we use water-based sublimation inks in sublimation printing, we often ignore some of the problems. Sometimes these problems can make the printed images very poor and may even cause damage to the nozzles. Therefore, we cannot ignore these issues and we must pay attention to them. Here are some common questions and things to note.
1. When sublimation printing, pay attention to controlling the parameters of heat transfer sublimation ink, including ink viscosity, fluidity, thixotropic and plasticity.

2. Pay attention to the control indicators of water-based ink. The control indicators of water-based inks mainly include fineness, viscosity, pH value and drying speed, which play a decisive role in the application of ink.
3. Since the aqueous ink is a pure aqueous system, care should be taken not to mix the aqueous ink with the alcohol ink and the solvent ink or to add an organic solvent to the ink to avoid printing quality problems.
4. When using water-based ink, it should be stirred evenly. After measuring the viscosity, pour it into the ink tank. If the viscosity is not suitable, adjust it with thinner or thickener, and pay attention to controlling the pH value of the ink. Generally, it is controlled at 8.5~ 9.5. During the printing process, due to the volatilization of water, the viscosity of the ink will increase and the pH will drop. Therefore, the use of the ink should be observed frequently. If the viscosity of the ink is increased or the pH is outside the control range, the diluent and pH stabilizer should be used in time. Adjust to ensure viscosity and pH stability.

5. Under normal circumstances, the sublimation printing ink is very suitable for high-speed printing. If the drying speed is too fast or the printing effect is not good during low-speed printing, a certain proportion of slow-drying agent can be added.
