IBM TDS800 user manual Resolution

Note: Only choose ‘Group 4’ or ‘Group 3-1D’ when you are sure you can use these compressions afterwards. Choose ‘None’ in any other case.

Note: If you scan greyscales or dark originals then use Group 3-1D compression. In these cases group 4 can increase the file size.

Note: ‘Group 4’ or ‘Group 3-1D’ are compression methods which are optimized 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.

Note: Only choose ‘Group 4’ when you are sure you can use this compression afterwards. Choose ‘None’ in any other case.
