The dispute concerns the person whom the corpse used to make the imprints belonged to, and the age of the cloth. I don’t think anyone serious can postulate that the entire imagery is a handmade fake. When a corpse is used, 3D stereoscopic features are bound to be preserved. No magic here.
WiKi has a great amount of detail in its article on it, with cited references:

I think I understand your point, however are you suggesting that a mock crucifixion was preformed in (say) the 1200’s, for yet unknown reasons, which produced this artifact? The Shroud also includes pollen spores from the area around Israel and dates back to around the period of the original crucifixion.
I may have entirely misunderstood your point, if so my apologies in advance.
