 Harry,

Ideally you would print the wedge file and then measure the results with a
reflecting densitometer. You could then see if the density readings are in
5% steps and adjust your curves accordingly. You can pick up used
densitometers such as the X-Rite 810 on eBay in the $200 to $300 range. You
can also use a flatbed scanner to "measure" your printed wedge. Not as
accurate as the densitometers but still better than an eye ball comparison.
Even without these you can get a pretty good screen to print match comparing
your printed wedge to what you see on your screen.
