I worked in support for a large copier sales / support company many years ago. A year or so after we launched our first analogue colour copier I took a call from someone at the national forensics laboratory asking how a counterfeit could be detected if it had been made on any of our devices. I replied, in all honesty, that it wouldn't look anything like the original and would be dripping in silicon oil. He seemed quite happy with this response and and far as I am aware it was never tested in court.
