There are foils used with laser printers to create gold and other metallic looking logos for fancy stationary. I used to buy it decades ago. If I remember correctly, it was/is called Omni-Chrome or something like it. I also used it for making dense artwork as described below. I think that company is just using that same material and re-labeling it as special product for PCBs. Bertho From: Confidential Sent: Saturday, September 01, 2012 05:58 There is a relatively easy solution. From the PCBfabinabox product there is something called TRF, or toner reactive film. You apply your toner to your board, then place a piece of this toner film over and run it through a laminator. Peel the TRF film away and it will leave behind a very opaque substance on the PCB that only sticks to the toner. Perhaps this might help. http://www.pcbfx.com/main_site/pages/products/toner_foils.html Neill [Non-text portions of this message have been removed]
