Text export in black not possible?

[kaledo]

Obwohl ich Text in Schwarz (RGB 0-0-0) angelegt habe, wird er im PDF-Export zur Mischfarbe (CMYK 89-78-62-97). Was mache ich falsch?

 

Although I created text in black (RGB 0-0-0), he becomes in the pdf export the mixed color (CMYK 89-78-62-97).

 

By the way: I tried CMYK 0-0-0-100, also the Black/White Circle. No differenz.

 

What do I make wrong?
