I'm submitting manuscript to a journal that requires 1200 dpi in my images. I have changed the dpi from 96 but when I upload the image with 1200 dpi, the image looks super blurry when I review my manuscript. If I open the image in word/paint/other the resolution is great but in the submission it looks blurry. It is the right dpi but it is impossible to see the figures. What should I do? I don't want this to be a possible reason for the journal to not accept my manuscript.
