1. Adding inappropriate solvents will cause the friction of the equipment to increase, which will make the printing equipment depreciate faster; at the same time, it may cause frequent stoppage of the ink plug. Start-up operation speeds up part wear and reduces production efficiency.

2, the good dissolving power makes the appearance of the ink have a homogeneous texture, so that the ink has stable viscosity and fluidity, and it is not easy to be gelatinized. The addition of a suitable cosolvent can fully obtain the effect of dilution and dispersion.

3, the choice of solvent must fully consider the gloss, flatness, residue, fastness, ductility and adhesion of the printed ink film.

4, the function of the cosolvent is similar to that of the main solvent, so it is necessary to use the correct cosolvent to prevent the ink from gelling, loss of fluidity and viscosity.

5, due to the rapid development of printing technology and printing speed, it is necessary to carefully select the appropriate solvent, otherwise it will affect the printing workability, causing the ink to dry too fast, and the drying is too slow to easily stick back.
