Steve, perhaps you correct yourself later in the post (sorry, out of
time) but this is incorrect.
The entire path from numbers exiting Photoshop to ink hitting paper
does not clip as you suggest.

255 winds up mapping to your 0.043 paper, and 0 to your 1.65 ink
black. All in between is "compressed" accordingly. If you have
clipping such as you imply, there are other problems. The nature of
the compression is determined by your entire workflow and device
characteristics.
