I don't have the kodak chart...
I've downloaded it on the web...
So, it will be difficult to scan the original chart...
The aim of my scan was to show all grey shades... and to prove that I don't have breaks in the shades.
:)

The funny part of the story is that sometimes, when I look my printed B&W kodak chart, it's a little bit greenish, and sometimes, it's not.

I think it depends of the light or something like that (or what I looked at before)...

But I can say that my printed B&W pictures are not greenish...

Look up metamerism, or more specifically metameric failure.

Geek alert:
The term illuminant metameric failure is sometimes used to describe situations where two material samples match when viewed under one light source but not another. Most types of fluorescent lights produce an irregular or peaky spectral emittance curve, so that two materials under fluorescent light might not match, even though they are a metameric match to an incandescent "white" light source with a nearly flat or smooth emittance curve. Material colors that match under one source will often appear different under the other.
