The same brand of black pigment ink and black dye ink can be mixed with it? Will it block the nozzle?

I use the Canon MP198 printer, is used for the system, West Black pigment ink, now want to use West dye ink, because the price is much cheaper. Can I mix it?

Can not, should be the composition of the two kinds of ink is not the same, the color effect is not the same.

No, mixed with different inks will produce a chemical reaction that may produce a precipitate. Not recommended for use
