Great, can you send me a version of how you would like them to look in Grayscale, and also some information on the settings or corrections you did?

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.

Ok, which profile do you use for Gray in Acrobat?

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

I'd rather have stories told than be telling stories of what I could have done.

It's more like grip, grip, grip, noise, then spin and 2 feet in and feel shame.

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:
