I did a quick test using Acrobat Pro 9.5.2 and I do not get invalid fonts when I use the preflight flattener fix or flatten transparency from the tools menu.
The problem is with Acrobat Pro X. Really getting sick of this. I am ready to dump it and go back to 9.
Linked is another "Corrupt" font after Flattening: https://acrobat.com/#d=EY8hFfGtMn*PvpIJcHfLUA

We are still investigating here as we cannot duplicate this...

It appears that if you run the flattener by itself, as opposed to as part of a conversion to one of the PDF standards (such as PDF/X or PDF/A), then it will invoke additional font optimizations that are perfectly valid for "regular" PDF. As such, we are not inclined to correct it since it is doing it's job of producing the best possible PDF that it can, given all the information it has.
This is another reason why working with PDF/X (any flavor) from the start of the workflow will guarantee you the best results - because it clearly identifies your intentions.
Hey Leonard, why should Separation All never be converted to grayscale?
Because Separation All means that the object should appear on ALL plates but doesn't actually have a real color associated with it. Converting it to grayscale will cause it to appear ONLY on the black plate.

Oh well, seems like another workaround. I can no longer just use the Flatten transparency Fix, but must use one of the other Profiles that happens to incorporate it. Those more inclusive Profiles have pitfalls of their own in terms of unexpected results. I find the granular control of using individual fixups is essential when working with many PDFs.
Anyway, thanks for looking into this.

Thanks, but a good portion of printing done these days doesn't rely on plates anymore. The reason I'm asking is because those Separation All registration marks are the source of color click charge headaches in digital printing when the real intent is for B&W clicks for greyscale pages. A workaround is to use Pitstop to globally convert those marks to a single color. From a digital standpoint, it just doesn't make sense why it's considered taboo for Acrobat to convert registration marks as well when converting pages to grayscale. That's all.
The ink manager has a shortcoming (ink manager is the same in convert colours, or if you click on the ink bottle to get directly to it or approach it from the output preview or the advanced print dialogue) that the colours are not previewed as swatches. But the ink manager was designed so that you see if it is spot or process. If you use the output preview you can see the colours (if you need to see colour swatches to explain the name) Maybe in future we will be able to see something like the recolour artwork? Some of us are so seldom in those dialogue boxes because we do that part of the process in the RIP rather than in Acrobat.
