Hi Ed and Denton,

For Epson printers, they are actually RGB devices in that their software is
designed to take RGB data and do it's own conversions to it's CMYK or CcMmYK
colour space. If you send the standard driver CMYK then it converts this data to
RGB and then does it's own transformations to its CMYK colour Gamut.
If you are using a CMYK RIP then you should send it CMYK data. If you want to
ask any printer associated questions and get definitive answers then try

epson-inkjet@xxxxxxxxx or try www.leben.com for subscription info
