Lighten all pictures in PDF

Hey all,

I have a problem printing my 200-page PDF.

When I try to print the pictures turn out way too dark. I have tried to play around with my printer settings to make it print them in lighter tones. No success.

There is a workaround to lighten the images manually, however, there are over 400 pictures in that PDF, so going over every single one of them would be tedious work.

So here's the question: Is there a way to lighten all the pictures in a PDF at once?

Thanks.
