File type
Only choose ‘Group 4’ or ‘Group 3’ when you are sure you can use these
compressions afterwards. Choose ‘None’ in any other case. If you scan greyscales
or dark originals use Group 3 compression. In these cases group 4 can increase the
file size. Group 4’ or ‘Group 3’ are compression methods which are optimised for
text and vector drawings. If you choose these compressions when scanning a photo
with many greyscales these compressions can result in a negative compression: the
file size increases instead of decreases. So use these compressions with care.
