I don't have a magnifying glass but I tested with print to file and
the I used the unprint utility included in gutenprint. There is cmy
and k involved in the print.

I printed a cmykramp from cinepaint and used the unprint tool on this
one to. Here is a view of it magnified 8 times.  I have written the
actuall cmyk values before print in the image. It is also converted to
rgb for nicer web view.

It looks like the strip with only a K value, the lower one, is printed
with black only inc. In the patch at right there is also something
that I guess is light black ink.

Epson R2400 printed with direct cmyk print cinepaint.

Thanks again.
