Considering the plastic that coffee cup lids are made from what would be the best quality way to print onto that, that wouldn't transfer of rub off?

I've been in the print / sign industry for over 14 years and do not know any way, quality or otherwise that would allow you to print on a coffee cup lid.
The formed plastic shape of the lid would in my mind at least inhibit many of the printing processes that exist, and I don't know how feasible it is to have the lid manufacturer print before forming the lids, as the heat and stress would probably destroy the print.
If you are DIY then I suppose you could make a custom pad press but it seems to be a lot of trouble when you could print on the cup itself or a "Starbucks" type sleeve much easier. Just search "print coffee cup sleeves" on Google for a long list of vendors.
Alternatively if you have a huge run (20,000pcs or more) you could have the lids custom formed to have raised lettering or logos that won't fade or rub off.

If one has a lot of cash then it would be possible to inject 2 different plastics. Some Direct-to-Substrate inkjets could also do this.– joojaaCommented Sep 17, 2015 at 11:45
