— The software might not recognize text that is tightly spaced. For example, if the text that the
software converts has missing or combined characters, "rn" might appear as "m".
— The accuracy of the software depends on the image quality, text size, and structure of the original
and the quality of the scan itself. Make sure that the original has good image quality.
— Colored backgrounds can cause images in the foreground to blend too much.

clean.
