I’m making a keychain with a John Wick design. As you can see it takes to leather engraving very well. However when I engraved on Pg medium acrylic I got a bad result. Only when I hold it to the light and tilt it do I see the image I thought would get in the first place. Most of the time it looks rough and unidentifiable. I tried scoring the image and that looks even worse as you can see. What would you recommend for getting a perfect image on acrylic?
