Electro Etching - Toner transfer
Small piece of brass that would fit into the aluminum heat spreaders was cut out and sanded down with 400, then 600 grit sandpaper.
The test image was printed on Pulsar FX Toner Transfer Paper. I choose this image for the fine lines and small details as well as the larger solid section.
The brass plate is then degreased with a dab of TSPe, and carefully handled after.
Here's the sandwich!
Top shelf of the oven!
Water removes the transfer paper from the toner resist. The paper floats away easily, and feels exactly like the paper found on the underside of water slide decals. A quick google search indicates that these papers are probably Dextrin Coated Paper.
Success! The toner transferred well, and seems to be very sturdy. It even resists my attempts of scratching with a fingernail. However...
The fine details are all squished. Was it too much heat? Or was the clamp applying too much pressure? Gotta sand it off then and try again! I'll report back when I get a better result!
