Xerography would be even more precise, so the object is not precision but to adhere to the tradition.
Folks who are into that have my OK if you need to know. I'm not into tradition all that much.
"Xerography would be even more precise, so the object is not precision but to adhere to the tradition."
The object is both precision and law as mandated by the Torah.
Every aspect of writing a Torah scroll is laboriously done by hand. All materials, parchment, pen, ink, are strictly regulated. All writers must be of the faith and practicing Jews. The formation of each and every letter is proscribed.
When was the xerox invented?
The Torah has been copied for over 3,000 years.
How so?
so the object is not precision but to adhere to the tradition.
That's a pretty definitive conclusion from fairly speculative assumptions.
