Malcolm,
My original goal was to do the process with commonly found materials like parchment paper. But when I gave up on that approach and went with the China paper, I should have reviewed the archives. I think you have suggested this paper before and it is easy to find locally. Costs more than parchment paper but it sounds like it work. The trick of freezing is truly an advancement in the art.

Confirmed. I use this paper for all my toner transfer PCBs and brass plate nameplates, but was soaking in water with detergent and dishwasher rinse aid after transfer. The final white layer was difficult to remove, particularly on small holes and you had to scrub quite hard to remove it, risking damaging the thin tracks. Changing to freezing after transfer completely transformed the process, small hole centres are now clear of deposit on peeling.
