The title already tells most of the problem I have. When I export my file to JPEG or PDF, it's quality get very low. I've already tried to switch the resample option to Bicubic or Lanczos, which didn't give me that much of a better result unfortunately. However, when I export the file to PDF, the quality is stunning.
I've also tried to change the document settings from 72dpi to 300dpi, which also didn't give me any other results. Could anyone please help me out here?
Below I've added an attachment to show you guys what I end up with.
Thanks in advance!
