If i print a drawing with a hatch, the hatch is printed in pixels.

Normaly this shouldn't be a problem but our company logo is developt from a hatch, and if i print it in the corner it is realy messy if i export it to pdf. The whole drawing is fully zoomable, and the quality remains but the logo is realy messey.

I tried to change the print settings, but without any result.

i have added a dwg and a pdf file, if you zoom into the pdf file you see the pixxels.

I hoe you can help my.
