I do 3D renders and whenever I convert my rendered PNG/JPG into PDF, and whenever I view them on Adobe acrobat on android, there's always this blurry contourish look, like on this man's head and neck for example. I've tried using the highest quality settings for both image formats like "quality:lossless" and "pdf file size:large", but it doesn't solve the problem.   When I view the pdf on acrobat PC version, it displays correctly and so I thought that the problem lies with my phone. But when I converted the images of other people who do 3d renders, the converted PDFs from their images look much better on acrobat android - there may still be some of that blurry coutourish look, but still nowhere as bad as mine.   I also tried converting photos downloaded online and I also get this blurriness. please can someone tell me if I'm doing something wrong, this is driving me nuts. Thanks in advance for all the kind help! ... View more
