pdf export, monochrome

Hello, 

i try to export a pdf from V1R2 using the "Export to pdf" function.

When i use a pdf printer and choose "monochrome.cbt" print style, the pdf is in monochrome.

Same result when i use the internal pdf printer.

But when i use the "Export to pdf", that is not in monochrome.

I think i tried everything, but i just dont get it to work.

Is there anything that i can do more than choose a monochrome style ??

 

Are the settings for the pdf export somehow adjustable ??

 

Best regards
