Hi.
I am sorry but from Italy I can't open the pictures that you posted on dpreview
because the internet site seems to have pedopornographic contents in it (not
your images, of course, but some images on the internet site).
It would be nice if you can host them somewhere else to show us your "product"
:).
As I wrote in the video description and in the previous email I found it to be
very easy to read the patches with the ColorMunki and using just a simple
ruler. The simple rule is this: if you want to read AA strip you have to put
put the ruler between AC and AD strip to use it as a guide.
I only had problems with the last stripes because I could not find a "guide" on
the sheet of paper, but you can "open" the spot reading guide of the
ColorMunki, put it in place and start the readings with no problems.
This is the output of profcheck:

This are the wrost patches (I ordered from wrost to best using MS Excel).
This result is also better that the one I can get using "regular size" and
-smaller size patches in printtarg for ColorMunki (printtarg -iCM and printtarg
-iCM -h).
The resulting profile seems very good for the number of patches used, so I
really suggest to all ColorMunki users to give printtarg -ii1 a try, you can
save paper and probabily time.

Hi Vittorio and all,
One of my friends uses a self-made ruler for the ColorMunki spectro, look at

Hi all.
I would like to share this video I made to show how simple and fast is to read
a test chart, made for the i1Pro, with che ColorMuki spectro.
This is the link: http://www.youtube.com/watch?v=9PebBQOpP3I
In the video you can find a description on how to use a ruler to easly jump
from one strip to another.
I think that maybe in the next release of ArgyllCMS the ColorMunki could have
an "-h2" parameter for using the i1Pro standard patches while making the test
chart file.
Something like: printtarg -v -i CM -h2 -tResolution -pDimension fileName
Let me know what you think about this.
Have a nice day.
Vittorio Villani
