Certainly a good read about the microdots. Though according to the article it seems that the microdots simply reveal the date and time the document was printed and not what exactly is on the document. Also if printing a sheet of say 30 labels, it doesn't seem that every label would have these microdots within it. These microdots are probably somewhere on the page but not on every single label. I could be wrong but this is just my interpretation. In other words I don't think someone could take a label off a bottle of juice and be able to identify who exactly printed it.
