Let's see if I can do this coherently...
So you want to make 1% and 2% print values with a 25% ink. First of all it's a light ink, so it doesn't have much contrast 
against the white paper base and the dots will be hard to see. Secondly, since it's only 25% print value at 100% ink load 
(hypothetically), it'll take a higher percentage of that ink to reach a 2% "print" value than a black ink. So already the dots 
are closer together than they would have been with darker ink.
Dots of lighter ink that are closer together are very hard to see compared to the same print value created with black ink on 
white paper with widely spaced dots. Argh! I can't talk! Anyway, things only get better as you move down the scale, but 
new problems arise as you reach the max each ink can do and bring in progressively darker inks, as well as total ink load 
the paper can take without getting muddy.
Is that what you were asking? Did it make sense as an answer? Is there life after death?
