How can I get aligned pages WITHOUT text quality worsening?
I know how to get Adobe Acrobat to align the pages: “Scan & OCR” > Enhance > Filters > Deskew (On).
But it seems that when a page is aligned (“deskewed”), the text becomes slightly blurry. This happens even if I have chosen to have no image compression.
Why does this happen? I consider this a bug. How can I have the same image/text quality when a page is deskewed?
What is your image resolution? You can find out by using either the preflight tools to get an inventory of your images, or by using the "Object Inspector" in the "Output Preview" tool. I have never noticed that scans would get blurry when using deskew, so either my eyes are not get great, or it has something to do with the source image, and the most likely culprit would be the image resolution. One other explanation could be that the scaned image was saved with JPEG compression (which is a lossy format), and in order to deskew (or do any other image cleanup), the image would need to be uncompressed and re-compressed. This would introduce more compression artifacts, which could be interpreted as blurryness.
