Hi Folks,

Can anybody tell me the RGB values for the following Canon printer
colors?

Cyan
Magenta
Yellow
Photo Cyan
Photo Magenta

Any information would be much appreciated. Thanks.

Which inks for which printer?
While ink formulations are likely similar across generations of printers,
meaning that a new printer is likely an old printer in a new box (Canon is
the world leader in repackaging old and marketing as new) there could
actually be differences in the formulation of inks for different Canon
printers, presuming you mean dye based inks.
The real answer is: you have to measure those values directly off a print
and they may be specific to the paper substrate.
The absolute RGB values of the inks are not as important as the ability of
the printer driver to create a reasonable facsimile of a specific RGB value
in printed output.
Alas, in my experience, Canon is less accurate than Epson in a color managed
setting.
 
I'm sure you need the rgb values that a printer prints only one pure color
(e.g. magenta). Am I right?
It's a difficult task to calculate/measure these values. And depends on the
type of paper you select and may the printing software (in other words, the
internal color profile).

Yes, that's what I was looking for. I'm setting up a page of vertical
color bars that I can use to keep the print heads from drying out. I
figure that I'll just print one page every week that I don't use the
printer for anything else, and that should keep them fluid. I'd like
to have the colors of the bars as close as possible to the pure color
of the ink, so that if I see any imperfections I'll be sure that the
problem is specific to that color rather than another one that's been
blended with it.

That type of file is available from Inksupply.com and is listed as a purge
file. You can download the purge file that is designed for the number of
colors of ink that your printer uses. You can also reduced the size of the
purge page in a program such as photoshop to use less ink and still keep the
head from drying out.

For this purpose, you won't be far away from the pure colors if you choose
(rgb):
cyan 0/255/255
magenta 255/0/255
yellow 255/255/0
black 0/0/0
(light cyan 128/255/255)
(light magenta 255/128/255)
If your printer has two blacks, may someone else could inform you better
than me.
