The way to test this is to start with a tiff file from a well-focused
scanner (assuming a 24-bit tiff file is what the scanning service
offers).  Then, take this 24-bit tiff file and produce a jpeg file
at approximately 7:1 compression.  The comparison is then
between the original tiff file and the jpeg file.

Taking a jpeg file and producing a tiff file from it isn't useful.
