Duotones process a single grayscale image into ramps of two different colors.
Proofing how those selected colors and their tints will look on a press, to
an inkjet requires that you accurately define the two color values, and how
they gradiate and blend at different percentages. Using a RIP with accurate
named color callouts for the two inks would be appropriate if you are
actually printing with two known-value spot inks (Pantones, most likely), so
that those Pantone values could be defined for your inkjet. If you are
printing the duotones in emulation on the press, with process colors, then
they are not really duotones, and you may be best off emulating the duotones
in RGB or CMYK in the first place, and sending them to the proofer and press
that way. This would move them from named color territory to image pixel
values processed directly through the device profilem so any color managed
RIP with press emulation capabilities could manage it.
