The removal of DRM from a topaz book can definitely result in ocr-type errors that do not occur in the original format. That's because the DRM-removal process uses the underlying ocr-text (included in its—usually—uncorrected form for text-search purposes) to "recreate" the text of the ebook. Because the original version is individual glyphs drawn on the screen, and impossible* to recreate except as SVG images of "pages".

With all other formats, DRM removal has no effect* on the actual content.



* except for the rare and/or obsolete ones I'm forgetting--which someone will certainly blast me over should I neglect to include this disclaimer
