Oops...missed this post.

If you convert any of them using the Acrobat setting and then use curves in Pitstop changing 92-94% to 100% is the look I am going for. None of the existing CM settings give me that look. And if it makes any difference the conversion is not all that bad when converting a CMYK 4 color B&W to grayscale but RGB B&W to grayscale almost always looks bad.

Here are the Acrobat CM settings along with the edit screen for the Acrobat preset that comes with Pitstop.

Where'd this ever net out? I set my profiles to Joe's screenshots above, trying to convert a 16pg book with all RGB (should be grayscale) photos & they look flat, no matter which conversion method I try.

Went back & watched the webinar too, the Clean up Black Global isn't any better than the Convert to Color Space.
A little diddie 'bout black 'n cyan...two reflective colors doin' the best they can.

Yeah that is my issue as well. I usually use the Acrobat profile to convert images and then adjust using Pitstop Curve and Brightness/Contrast tools to make them look better. Then I turn off Pitstop color management and run the convert to grayscale action list to convert any vector and text. That is on days when I feel generous. Other days I just convert everything with color management turned off and too effing bad for the dumb-ass people that can't create proper files in the first place.

We don't have a RIP, so we convert to K like this:
