Ink composition questions

[jerik]

Is the ink inside a OEM BCI-3eY different from the ink inside a CLI-8eY, and BCI-6Y?
BCI-3eM, CLI-8eM, and BCI-6M?
BCI-3eC, CLI-8eC, and BCI-6C ?

Is there a difference in the ink in BCI-3eBK ,PGI-5BK and BCI-9BK?

Thanks

According to Canon, the BCI-3 cartridges use Canon ink.
According to Canon, the BCI-6 cartridges use Canon ChromaPLUS ink.
According to Canon, the CLI-8 cartridges use Canon ChromaLIFE ink.

Each of these are different formulations and some of the colors have differences in color values.

The PGI-5BK is a pigment black ink. It is used for text printing on PIXMA model printers.
