Increase the contrast of the black text in a PDF document

Post by Carmina Burana »

Thanks for welcoming me into the forum!

I'm new here and have a question. I hope an expert can help me. Thanks in advance.
Is it possible to increase the contrast in an existing PDF document using the PDF-XChange Editor, i.e., make black text (on a white background) darker? If so, which function should I use?
