Input image files can have resolutions up to 600 dpi, but 300 dpi (both
horizontally and vertically) is recommended for optimum OCR accuracy.
The program stores black-and-white images at their original resolution,
but grayscale and color images are not usually saved above 150 dpi. That
means these are not good candidates for future OCR processing.
Hover the cursor over a page thumbnail for a popup window showing the
size and resolution of the original image.
If you try to save a black-and-white image to JPEG format, the program will offer
conversion to grayscale. With TIFF G3 and G4 it will offer conversion to black-
and-white.
Saving to PDF format is supported, with five options. Two of these, Image only
and Image on text, export original images. This is done in the Save As dialog box
for recognized pages. See "Saving to PDF" on page 84.
