If I understand correctly, seems that the problem is visible with deeper
blacks. Graeme Gill said:


” For instance if the black on your printer aren't super deep (say L* of >
5) you may not notice the problem, since it's mainly due to some electrical
interference within the ColorMunki between the LED driver and the spectral
sensor, and a sufficiently large level of light will swamp the error.”

Thank you for your continued work.


These ColorMunki findings could explain a few things and unfortunately also
raise some questions.


So, may be this is why I often had "inconsistent readings" kind of errors
during chart readings when I was sure I moved the CM correctly (from paper
white to paper white, smoothly and slowly, but not too slow, along a locked
plastic slider on a drawing board) and the printer wasn't "that bad".


Should I declare any printer profiles I made since I updated to v1.5 unsafe
or even false?

This could be a bit problematic since I had this bad habit of recycling the
papers in a few weeks after I take the readings (I use the photo papers for
various non-printing related tasks as scratch material) because the thought
of a scenario like this did cross my mind. But I considered it very
unprobable, while difficult to keep the papers in a dry environment to
preserve them for more than a few weeks anyway.
