This is my first time etching an image with tones other then black. As the engrave starts at the bottom things look ok, then it fades to almost nothing. If you look at the jpeg you can see the tone should be consistent. At some point, when there are darker values to etch the laser kicks back on. I used the SD Graphic setting. I tried HD, but it said the file was too big, which was surprising because it’s only about 5x13. So these are my issues. Any thoughts on how I can get a cleaner, more consistent engrave? Thanks.
Attached is a picture of the two engraves I attempted on non proofgrade birch plywood. The second image is one of the digital files I wanted to engrave.!
