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?
If you put this in the machine it will engrave the black area, but leave the white untouched - which should make it clearer on a clear acrylic. An example of an image on clear acrylic: Gandalf Acrylic Key Ring (that one may also be helped by covering 90% of the surface!)
Well you’ll never get good contrast with clear acrylic unless you do color in the etched areas (acrylic paint works great, sticks to etched surface & easy to rub off the smooth/unetched area–test the tool first to make sure you don’t scratch the acrylic while trying to remove the paint–I like wood ice cream bar sticks myself).
In PhotoShop you can “invert” with “negative image” tool–it’s under “Image” top menu bar I think–just click until you find it in the pull down menu that appears under each category, or just search for it in the Help of the software you’re using.
But remember, dark areas are cut away, so inverting might not be the look you’re after.
