Why does my dual-cure emulsion break down with water-based ink?
Many people in the screen printing industry believe the “dual” in dual-cure means that this emulsion is resistant to both solvent and water-based inks. Although many dual-cure emulsions are resistant to both inks, this statement is not correct.
The “dual” in dual-cure means that the emulsion uses two sensitizers. One is in the emulsion before mixing, and the other is usually a diazo added to the emulsion by the user.
