The black "registration" is used, for example, for printing marks...
In fact, it is a mark (surface, line, etc.) that can be found in all colors (CMYK, Pantone, spot colors) when printing in color separation.
One mistake not to make is to place a text in black "registration" alone when printing in separation, because not finding any other colors, the RIP considers that there is nothing to print...

Thank you very much!
So I understand that it shouldn't be used for text but only for markers because it can cause issues for printing...
However, it's a 100% black quad, so I'm struggling to understand why it doesn't print... Is there a way to check this by oneself (in InDesign or Acrobat, for example)?

In printing, we try to keep the ink coverage rate below 300% (often printers even request 280%), meaning that the sum of the percentages of the four colors (C+M+Y+K) should not exceed 300%. However, with the "registration" black, we are at 100% for all four colors, leading to a total of 400%.
If you only have "registration" black on your sheet, when separating the colors, the RIP finds nothing to separate because there is no single color (either magenta or cyan), and therefore the job is rejected. However, we still have some tricks to make it work! .. but this is not a normal procedure. This only concerns color-separated printing; in composite printing, there is no problem.
In Acrobat "Pro," there are tools to check the coverage rate and the color separation (menu "Tools/Print/Output Preview").
