QTR-Quadtone RIP

Tom

Have you tried doing a nozzle check? With the K7's using so many
shades of gray, if one fails the image will still print but will look
 as you said - a blocked up shade of gray.
If your printer is working properly, then another thing to try is
using a different profile. I've had good success using the QTR
Gray-Lab and Gray-Matte profiles (convert to profile).
