Michael,
Just to sure it has been said in this discussion. The measurement of dot
gain is based on two factor. 1. The physical change in the dot size and 2.
something called optical dot gain. That is how the eye sees the change of
the dot based on how the dot is printed on paper. The combination of those
to factors is what dot gain is based on. Of course this is all formulated
into a equation that is built into a tool like a densitometer that measures
percent dot area.
A common communication mistake is to only look at the physical dot gain and
then discuss the dot gain issue with someone who is thinking about dot gain
that is calculated using both physical and optical dot gain measurements.
This might be what is going on in your case. But then again you might only
have a 10% dot gain.
