Transfer the toner to the PCB plate.


Here is where the magic happens.
At this step, everything is up to you. Remember the first page of this tutorial. The toner is a plastic. The right temperature is the key for good transfer.
If the iron is not hot enough, the toner will not melt and stay on the paper.
If the iron is too hot, the toner will smear on the plate.
The best results with this method are when the temperature is right and the pressure applied is as much as possible.
I use the tip of the iron, so more pressure is distributed on less surface. I start ironing from one side to the center of the plate with back and forth movements. Repeat it from all sides and pressing as hard as possible. Using a laminator machine is also a good option, since it presses the plate between heated rollers.

After the ironing, leave the plate to cool by itself. Here, the fact that paper and plate contract at a different extent, when cooled, works for you. This way, the toner remains on the plate, not on the paper.
Peel gently the paper. It should go with no tension.

Good toner transfer to the PCB plate.

Use a permanent marker and a sharp tool to make right the small defects.
If you are not happy with the result, clean the plate with acetone and start over.
