QTR-Quadtone RIP

How do you know what you fist value is suppose to be?

I read the turtorial and it wasnt very helpful.

For example;

QUOTE
Figure 1 is an example of the ink test on an Epson 2200 with Epson
UltraChrome inks. With a loupe or a densitometer you look for a patch
  where it appears that all the paper is covered with ink. In this
particular case it is at about 85% on each ink. There is a very
gradual increase in density after this level but when adding inks
together we don't want to overload too much. For this example I picked
85% for the basic ink limit.
END

I have a densitometer and waht value am I lookign for in the initial
run?  How do you tell when the paper is covered in ink???

This is confusing.

Thank you,

Kev
