it works. toner transfer is fine.

Pulsar has white film that does silk screen.

Toner transfer to the PCB for silk screen then use ANY laser transfer
craft foil (eg. Ebay # 160937797413) for ANY color silk screen.
If u look at my EBAY item number 131838128238 closely.
You can see blue foil applied to toner on the back of FR1 board as a
means of labeling.

Just so long as it is not conductive, so I'd check the metallic foils
carefully.

Foils are also perhaps available in stationary stores, office supply
stores and craft stores in the US. No idea about how the pricing
compares between all the sources.

Any idea whether the white TRF foil will transfer using
the cold toner transfer process?   Or should I be the one
to experiment?    Unfortunately, I don't presently have any
of the white TRF.

That second eBay number must be incorrect Ancel? Doesn't come up.

I'm sorry, it sold.

I don't think you can use a cold process with the foil transfer.
