I would imagine that the raster file will be whatever depth has been chosen for it, ie, 8 bits/component by default. It may be possible to select (say) 16 bits/component for the raster file when it is created, giving double the precision, but this may depend on the version of Photoshop. Of course all this is moot if the printing system being used doesn't have a 16 bit rendering path.
I don't really know much about bits and how computers handles numbers (sorry for my noobness). Would 8 bits be sufficient to store numbers generated by targen? I guess Ghostscript can be used to print the postscript charts. Martin W
