we all should learn to read between the lines :o)
Putting the question with an example:
step 0 (12 bits) = step 0 (16 bits)
step 2000 (12 bits) = step 32000 (16 bits)

The specifications from my Microtek Artixscan 4000t (the same as the
Polaroid Sprintscan 4000 in another box, except for the firmware) state a 36
bits depth. The Microtek scanning software (ScanWizard Pro) allows the
choice between RGB 24 and RGB 48 bits. It seems that the maximum resulting
I
suppose that the white point is converted from step 2^12 in the 12 bits
scale to 2^16 in the 16 bit scale and the intermediary steps are just
interpolated (without any gain in the image quality). Am I right?
Sorry, you're not right. I believe the 12 bit data is raw data with no
setpoints

It's my understanding that there are only two recognized TIF formats, one for 24-bit data and one for 48-bit data. So a scanner that outputs 36-bit data is going to actually give you a 48-bit TIF file, since the data won't fit into the 24-bit format. It would be nice if a standard existed for
