First point of issue is that the article is on Huffpo, a greater den of credulous knaves you will not find, tis a place where science is thin on the ground and what there is tends towards the pseudo end of the spectrum.
Second, the article has no useful links to further info whatsoever, don't even know where they culled it from.
Third, I have a hard time buying that the Italian National Agency for New Technologies, Energy and Sustainable Economic Development would be in the business of shroud analysis. Not saying it's impossible but it does seem well outside their purview and a waste of resources. There is also no news of this in the Agency's sites news section.
Apart from online news sources there is no further info as to how they went about their investigation and what their data was; we're just left to go on the alleged words of Prof Paolo Di Lazzaro. His words that they just looked for verifiable evidence with the hope it would start a theological debate to be answered by the "experts" are also hardly reassuring.
Apart from that it does appear to be an argument from incredulity as mentioned on Mr Doonhamer's link, "we've replicated the effect with ultraviolet lasers and we can't imagine what else could have caused it therefore it must have been with a high energy EM source." This based on an artifact that they have likely never touched and are thus bereft of vital information.
Given the info to hand or lack-there-of, their unclear motive and that they appear to be labouring under a fallacy; I don't think there is anything of note here.

There is a question over the radiocarbon dating, all samples came from the same area and that area appears to have been repaired after fire damage thus contaminating the sample with more modern fibers.
Hope is but the first step upon the road to disappointment.
