For background, see the post preceding this one, and the
200+ from this blogger that preceded that.
You see, thinking evolves as one experiments and collects
accumulates more data, one's own and occasionally other people's.
Early on, here on this site, I proposed that the TS image
was produced by heating a hot metal template, in the form of a naked man with
hands crosses over groin, and then pressing into linen that was placed over a
sand bed or similar (layers of sacking etc|. I didn’t give that technology a
name, but will now. Let’s call it LUWU (pronounced loo-woo), short for Linen
Underneath With Underlay.

Later I began to have doubts as to whether the image so
produced was a good enough match to the real TS. The scorch marks had
well-defined edges, in contrast to the fuzzier image one sees on the TS. Might
there have been a subtler way of deploying the template, while still retaining
the idea of a contact imprint?

| Mark 2 "LOTTO" method of imprinting (Linen On Top, Then Overlay) |
Thus was born the reversal of the initial
technology, in which the hot template was laid onto a hard, heat-resistant
surface, covered with linen, then an overlay, and the two layers (linen and
overlay) then moulded with hands around the contours of the relief for a minute
or two, using conducted heat (and discomfort) to signal when it’s time to stop.
That methodology was given a name (LOTTO - Linen On Top, Then Overlay).
