My EPUB contained many HTML tables, many of which would break on small screens. I therefore took screenshots of the tables and inserted the images into the EPUB in place of the HTML tables.
I just viewed my EPUB on Adobe Digital Editions (ADE) for PC. The table images look terrible! The text in the images is illegible.
The images become blurry only when ADE downscales them. If I expand the window and force ADE to upscale the images, they look better. At full size, they look crisp.
I have been looking for an answer to this problem ALL day. The best one so far is to create new images of the tables, this time using very bold text and thick lines. This works quite well. Most of the images become legible; however, they look very ugly, and some still look quite terrible.
Does anyone know how I can fix this issue?
