Hi, David,
This is true, but I wonder what happens if the shrinkage is anamorphic
or "cylindrical" so it approaches an oval? The process uses optics to
set the (generally) short side relative size but a combination of speed
and optics is generally involved in setting the (generally) long side
relative size (aka magnification).
My guess, like most analog items, the exact number Steve is looking for
is probably model- and perhaps even unit-dependent. I do recall in the
late 60s and 70s hearing that there were Gov't requirements that the
devices not scale 100% accurately for protection against counterfeiting.
Cheers,
Richard
