So, looks like you can't batch print to Preview on the Mac (open as or save as pdf option), only if you use a virtual printer.

However the main one available - pdfwriter, doesn't seem to be able to soft proof properly - you get a pretty ugly image on screen.

Also the soft-proofing options don't seem to be available.

So...possible to bath print to Preview ?

Possible to get a proper image via some virtual printer ?

Recommendations for virtual printer or how to properly set one up ?
