I have a pdf file that, when transferred to my kindle looks more "washed out" as opposed when I open on my pc screen: whites look a bit greyer and especially black text turn towards a lighter and thinner black, resulting in worse readabilty.

I cannot convert it to another format because the pdf is full of screenshot and imaged, which would not convert well in calibre.

Do you have any hint?

Thank you
