QTR-Quadtone RIP

Thanks Terry for the response.  I thought I may be the only one getting this result.  I've 
tried practically all curves that come with the R1800 and all have the same problem.  If the 
transition between highlight and shadow is abrupt, NK-7 doesn't seem to handle this well. 
Hope some others can provide some advice before I attempt making my own curves for 
this.
