CP are not dye sub (for their t-shirts anyway - they might be for other items). They started with digital inkjet transfers, they now also offer DTG in addition to the transfers.

To clear up something that may be causing some of the headaches: you can, under very limited circumstances, sublimate on cotton. Specifically there was one specific ink developed to work on white 100% cotton. It only works on white, it's significantly more expensive, and it's a new product. I don't know precisely how it works, but I can only assume that it has an inbuilt coating that bonds to the fibres, and that coating is sublimated (so it likely wouldn't be true sublimation in my opinion). Personally I don't think it even counts, but it does exist to help make things more confusing

any ideas as to what this is?

Discharge screen printing most likely.
