patches on each stripe, with other targets there are 36 patches in an

stripe. So maybe what you could do is to give the possibility for the
ColorMunki to
have an "-h2" and for the i1Pro to have an -h parameter with more patches in
each
stripe.
You can push it harder yourself by setting the appropriate options (-a, -A, -m).
I don't think it's wise to go below the manufacturers recommendations by
default though.
2) The procedure to read the patches in "-i i1 mode" is very simple and
reproducible:
you just need to have a ruler.
But what do you line the ruler against ? How can you be sure that the instrument
is actually centred over the strip within a fraction of a mm ?
What I would like to know is if you think that a more "full" test chart for the
i1Pro
could be possible.
It's all a trade-off between being generally usable, robust and accurate
readings,
vs. taking advantage of a specific set of conditions (type of printer, ie.
screening
resolution, print uniformity, accuracy of instrument guidance, printing
margins).
