background color printed on the table pdf

[fabrizio_brescia]

Good morning to all, I have a white electronic card that I put on the table.
I see the black background and the white card. if I carry the pdf also the background becomes white and therefore I no longer see the card.
is it possible in some setting to say to print the always black background? (or a specified color)

thanks for the help

I found the way by setting the colors of the black environment on white background, so what I see is how the pdf comes out.
