Digital BW, The Print

I have used 3rd party inks since 2002 with no problems. Maybe there  
are a few out there that have the wrong surface tension, viscosity,  
etc, but 3rd generation Cone inks are pretty damn clog-free. I would  
say even less clogs than Epson K3 with the 4800s and way better than  
the old Ultrachrome in the 9600s. Both Color and Monochrome sets.

Of course, when you run 10 30x40s a day for 3 years you see a lot of  
pressure problems, but I would say all of the 3rd party inks I've used  
have stacked up well against Ultrachrome. I've used both about evenly.
