Any Papers on Carbon Printed on PCBs?

Any Papers on Carbon Printed on PCBs?

I have an application where I'd like to print a carbon track on a PCB which will be used as a variable resistor. My switch will slide along it. I can find vendors that sell inks and also my circuit board maker says he can do it but I would like to see some guidelines for design. I'm interested in typical resistance variances (board to board), expected life with a sliding contact, force and springiness and material for the sliding contact and things like that. Anyone know of a good paper?

Thanks IR, that's the kind of stuff I was looking for.
