Not sure if this belongs here or Beyond the Manual… feel free to move it if need be.
I have seemed to run into a bit of a snag getting high contrast with my clear acrylic lately and I am not sure what has changed. It has been a bit since I did any acrylic engraving but my previous engraves were an opaque white and very high contrast. Now they are more or a transparent white and not as high contrast.
I have tried my luck with both Proofgrade and non-proofgrade acrylic. Both are cast, not extruded. I have tried nearly every combination of settings I can think of. I have tried raster images, vector images, vary power, and they all seem to produce the same results. Anyone have any ideas?
Here are a few pictures…
This first picture is how the engraves used to turn out.
And here is a comparison between the numerous tries I made on my GF and a quick burn my buddy did on his GCC 30w CO2. His is the eagle in the middle of the frame, which is the contrast I need to create.
Close up… the shield logo next to it is close but not near as clean or vibrant as his.
Any help would be much appreciated. Thanks in advance!
