Cheyenne high speed make carts spit ink at 10v+, I used rpg cart and a cheyenne rl 13 to test out white bold outlining today ( I never use above rl7 for lining I tend to use round shaders ) to test the lining ability of the Direkt. 9.4 volts single pass lightspeed hand : solid line. Fast hand speed : sick saturated white.
Hope it helps.
I still love the thunder for color packing and blending.
