QTR-Quadtone RIP

That was a strange outcome.
The problem is that without headings the code "guesses" what column is what.
One of the criteria is that L has a value above 90 -- and yours goes only to 87.
Anyway the easy fix is to add the heading line:

L A B X Y Z

This will make it clear that the first column is L.
