How to etch aluminum panel labels/designs with a reusable acid mix

Step 4 Transfer the design to the panel

Now we are going to transfer the design from the pnp-blue to the panel, same method as with the pcb toner transfer:

1.- Place the panel on some scratch piece of wood.

2.- Place the pnp-blue over the panel, make sure it's well aligned.

4.- Use tape to hold the pnp-blue on each side, make sure there are no air bubbles, wrinkles or deformations and the pnp-blue lies flat against the panel.

5.- Place some piece of cloth over the panel to protect the pnp-blue from the heat.

6.-Use an Iron to heat the toner on the pnp-blue, trying to cover everywhere, after a few minutes the toner will start to look darker, check from time to time to find any missing spots.

7.- When the toner looks black everywhere, the transfer is ready.

8.- Wait for the panel to cold down, then remove the tape, leave the pnp-blue in there.

9.- Now remove the pnp-blue, there may be some spots where the toner didn't transfer to the panel, we will fix that on the next step.
