The dye in the dye-based ink dissolves in water like sugar does in water completely.
Because of this, dye-based inks flow better and have been the standard in inkjet printers. But the dye will re-dissolve and the ink will flow across the paper if drops of water hit the paper.
For normal document printing on inkjet paper, photo paper, pvc card etc, we would recommend dye ink as it is much economic compared to pigment ink.
