Yes. It allows you to have your printer simulate a specified device profile and include media tint via Absolute Colormetic rendering. Also, allows adding a proofing color bar of your choice with the the IDEAlliance color control wedge a built in option.

That's right, no linearization capabilities. Only RGB profile building option. Proofs pass Ugra';s proof and print certification when wedge is scanned.

Latest version of Overdrive now includes layout nesting capabilities. My guess is you can probably achieve the same proofing capabilities via Photoshop.
> I also found much better success soft proofing with my custom CMYK profiles for XProof than with custom RGB profiles - not exactly sure why, I speculated that it might be related to the behind-the-scenes "extra" conversion supplied by the Epson RGB driver (to the CcMmYKk inkset), as compared to the XProof "drive the printer as a CMYK device" approach -- sorry, that's a long preamble to asking how well Overdrive RGB profiles soft proof.
No problems here softprooofing.
