I haven't had the occasion to print any duotones on a real printing press in years, so I am wondering if anyone has any recent experience with CS3 and InDesign and modern prepress operations?

I am looking for a nice clean bullet proof combination -- I am think PMS 415 with a tweak of the curve to deepen the 415 midtone and lighten the Black midtone. Save as a Photoshop eps with ASCII85 checked, place into InDesign and submit the collected folder with the source files rather than trying to set up a PDF... no proofing possible (other than lasers) and attend the press proof looking for good coverage and solid blacks. Printing on heavy white glossy 14-pt stock, a bunch of postcards set up on a 12x18 sheet.

I used to work in print production but like I said it's been probably 10 years since I last did a nice quality duotone... so any recent practical experiences would be good to hear about. Thanks
