“The shroud is [impressed] with the image of the body of a gaunt, bearded man with long hair.”
I knew it was over right there since if the writer can’t get that part right, there’s not much hope for him anyway.
The Shroud is not “impressed”, nor has it been “wrapped” around a model. The method described as a way to fake the Shroud won’t work because the Shroud has nothing soaked into the fabric.
The image sits only on the surface of the fabric, set there by a very short burst of extremely bright light.
I’ve often wondered if comparisons have been run between the Shroud image and the image on Juan Diego’s cloak left by Our Lady of Guadalupe.
Think of the outlines of humans left on walls in Nagasaki and Hiroshima.
