Why do some Canon inkjet printers have two black ink cartridges?

Thanks,

I'm not sure about Canon printers, but my Epson has two black cartridges,
one matte black, the other photo black.
I assume it the same for the Canon.

I think the large black on canon is pigment ink and the other is dye.

In technical terms, one pigment and one dye ink. But, in practical terms,
why?

Dye based ink is good for coated media but may be less suitable for text on
plain paper where the dye may bleed and leave the characters less sharp.
Pigmented ink does not bleed as much, it tends to stay on top of the paper
which makes it better for text. Pigmented ink is generally not compatible
with glossy photo media.

============================================================
I just bought 2 new Canon printers---The MP600 & the MP830. They both have 2
black cartridges--the small one is dye based and the large one is pigment black.
I was having a problem with the 830 and called Canon customer service. While I
was on with him, I asked the C/S rep exactly the same question. He told me that
the small black cart (dye) is used when printing in color--It comes out dark
gray on paper. The large cart (pigment) is used when printing text.

I think the question has been answered by the time I got to read it
this morning :O) My understanding was the pigment one is for fast
drying black text

Pigment inks do not usually get along well with dye inks. Since the
Canon uses dye inks for the color, for images, the black ink required
for that is also dye.

However, dye black inks tend to make less sharp text on plain paper, as
they spread on plain paper. To allow for sharp and quick drying ink for
black only documents, pigment ink works better, so Canon uses two black
inks. One for text/monochromic printing and one for mixing with colored
inks for images and colored documents.

On your Epson printer both are actually pigment inks. The matte ink has
more pigment in it, and is best for matte and plain papers as it has a
denser ink. The photo ink, if used on matte paper ends up looking
somewhat lower contrast.

The photo ink is designed for use with glossy paper where too much and
heavier and larger pigment particles would sit on top of the paper,
where it would make the paper surface dull and also tend to rub off.
