QTR-Quadtone RIP

Here's a link to a good article by Paul Roark on a related topic that
involves measuring dmax with a scanner.

You don't need to convert the L values you already have to density in
order to create curves using QuadtoneRIP. L works just fine.

If you want to convert L to density you can use Bruce Lindbloom's 
Companding Calculator at http://www.brucelindbloom.com/.
Alternatively, if you have multiple values to convert and are familiar
with spreadsheets, you can use the Lightness() and density() functions
 in the CurveEval2 spresheet that can be found here:
