Digital BW, The Print

Just installed (for the first time) Jon Cone's Special Edition K7s in my 
7800. Did a couple of power cleanings and printed a nozzle check. First 
thing I noticed was how light the 4th pattern from the left is--so light 
I can barely see it, but I can see that the nozzles are printing if I 
hold it just right and use a loupe.

So, is the ink really that light in that position, or should I work 
towards a more visible pattern?

Thanks!
