Hmmmm..
i guess time will tell if you're right...
but...does a man can buy paper good enough not to absorb that ink so much
that from 1pl drop a huge, 2 or 3 pl sized would result on a paper? If paper
absorbs too much ink it's useless to have 1pl dots... i guess all the fun is
that paper abosorbs ink in that way that those small dots merge together to
create nice, smooth picture...so, if dot is too small, they won't merge
(therefore whit space), if it's too large, they will interfere each other...
