All downloaded PDFs are not true black

Hello Community,

i've been researching this topic for a while and chances are very great that it will be misunderstood, as there are almost no topics on the net dealing with this issue (in a way that it affects me):

1. I create a pdf-file and it contains black text, and it stays black text (as it should).

2. I download a PDF file from the net, created by somebody else, and pretty much all of them are not black but RGB 33 31 29 or something similar, but not RGB 0 0 0.

Why does it bother me? Because every printout from my color laser printer creates dithered/rastered/diffused blacks and not true, unrastered black.

Spending days on google confirms that i seem to be the only one with the issue. Everybody seems fine to download and print dark grey documents.

I am using Acrobat Reader 2024.03 and not planning on investing 20 USD/months for a PRO version, just to print true black text with the black toner in my printer.
