So I have had this problem for a while: I have a document which includes many other .tex, .pdf, .png, .jpeg files. This document is around 200MB, but the problem occurs when only compiling parts of the document as well.
This is part of my documentclass:
\LoadClass[a4paper,11pt]{book}
\usepackage[top=2.5cm, bottom=3.5cm, left=2.5cm, right=2.5cm]{geometry}
\newcommand\bmmax{0}
\widowpenalty = 10000
\clubpenalty = 10000
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
I have already switched to a T1 encoded font because I was dealing with fuzzy-looking. That problem doesn't exist any longer, now my PDF looks mostly fine using Adobe Acrobat Reader Pro. However, there are a couple pages where the text is entirely bold-looking. Even the bold fonts are bolder-looking. Interestingly, it always occurs on the same pages in one document, even when compiling only parts of it. I wasn't able to create a MWE though.
I thought it had something to do with the compression of the pdf, so I tried explicitly setting
\pdfcompresslevel=9
It actually got a little better, even when commenting that out again or setting it to a different number. But there is still a slight difference between these faulty pages and the normal ones and it's starting to really bug me.
Has anyone ever had the same problem or might have a few ideas on what else to try to improve the quality of the PDF file consistently?
Maybe these can illustrate my problem a little better:
Left is heavy font, right is normal.
