Thanks for getting it done to compare results! I am excited to see apples to apples on the same image. Now we need to run the same image on an Epilog or Universal
Looks not too bad!
My comment is the areas where it is supposed to be flat are uneven.
The lower resolution DPI clearly shows jagged edges on lines that is supposed to be flat.
At the very center there is face. Look to the right side of the dinosaur between the teeth. Look how clean the image is on our raster compared to the uneven marking on yours. Now look to the right of that to the arrow. The edge of the arrow is not straight. All the areas that are black should be the same consistency but it is not on your raster.
Here is ours in comparison.
This takes about 10mins at 1000dpi on our $1625 laser. All you do is double click to "Engrave" button. No other prep needed
