Yes, ColorBurst can drive the Epson's in the same manner it drives the
Roland. The interface can control the mechanical aspects of the printer
(number of passes, dot size and type, etc) as well as all of the color
aspects (linearization, Ink Limit, ICC profiles, primary and light ink
curves, etc.) One of the main differences between Colorburst and the Epson
driver (and many other RIPs) is the way it handles the printer as a CMYK
device. The Epson driver and many other RIPs treat the Epson as and RGB
device whereas Colorburst will linearize, ink limit, and provide ink curves
for each separate channel. Therefore it is ICC profiled (with the new
ColorBurst built in profile creator) as a CMYK device with light ink
support. In the case of the Roland the same is done including orange and
green as a true six channel ICC profile (built with Monaco).
