LAB 7Blue Magic!Etching with PNP

Press-N-Peel or PNP is blue transfer paper used in the past for etching circuit boards. In this lab, you learn how to laser print or photocopy onto PNP to make unique designs in your jewelry. Black-and-white artwork like line art, drawings, or letters work best with this transfer paper. The toner will burn onto the PNP paper and can then be ironed onto metal.
