single dots with Pixma iP4500 ?

Hello,
here in our institute we use a Canon Pixma iP4500. We would like to
produce now thereby individual ink dots on foils. If I make the surface
smaller which can be printed ever more, then nevertheless a set of 4
dots remains as the smallest point. The dots has a diameter of 20 µm,
which corresponds exactly, which we expect.
Now we need however only 1 dot and evenly again and again in a certain
distance.
Does someone have an idea, perhaps under LabView ?
Thank you very much
and Best Regards,
Falk

What color is it? What I'm having in mind is trying to remove all other
colors from the printer (or put emty inks).
Maybe it's making 4 dots because you're trying to print a color which is
not exactly C, M or Y ?

I tried it with 4 different colors. Exactly the C, M, Y, and the K too.
Each Color brings the same result (more or less).

I also reduced the value for each color from 100% to 25% and 10%. The
number of dots decreases from 4 to 2 but sometimes there are color
artefacs near the dots.
If I print a pure Y, sometimes some blue dots also appears.
It is not very exactly then and maybe not usable for my purpose.
Thank you,
Falk

Grrr.. the only other thing - maybe try switching off any
'color-intelligence', like ICM profiles and try different paper/print
quality combinations?
Sounds a bit weird - can't print what you want to print.
