Even if the next lightest ink does not cover where you get visible
dots, you can still get a dotless print. Lets say we are talking about
full black and medium black. Full black becomes dotty at 60% maximum
density, medium black maxes out at 40% density (full coverage though)
keep your medium black at nearly full density and add in some full
black. This will increase the density, and you will still have full
coverage. As the percentage of full black rises, you decrease the
percentage of medium black until you get a complete hand off to full
black.

In theory this is perfect. In practice this has some trade-offs which
I explained in my previous post.
