Harlequin RIP and spot color handling for proofing

[ripready]

Hi,

I am running a Harlequin RIP with an Epson 9800 proofer (8 colors: cmyk + light cyan + light magenta + light black + extra light black). I would like to have my spot color channels output on the light ink channels. So for example, if I have a spot red, to have it output using the light magenta channel.

I know I can do this with some of the other proofer rips.

Anyone know if this is possible and how to do it?

Thanks
