I think I was the one you are mentioning. I said that it is important that
the number of grid points in the B2A tags be odd, not even. These are the
tags that convert from PCS (e.g. Lab) to device color. Having an odd number
of samples avoids the problem of interpolating white, which can lead to scum
dots. It really doesn't matter the even or oddness of the grid points in
A2B tags.
