So these are images of final results in testing and working the settings related to getting a great detailed image engraved on paper.
For everyone’s reference the following was used to produce this piece.
The paper is 12x12 - 78 lb. Natural Smooth Card Stock Paper.
The settings I used are as follows:
Precision Power: 15
Grayscale: Vary Power
Lines Per Inch: 195
Focus Height: 0.012 inches
I notice the Focus height was real key, as adjusting up to .013 or .014 or down to .011 or .010 really made differences in the detail and the .012 was just right for this particular image. Other images and paper weights may need to be tweaked from my settings to get the right result. But this is something to start from if you are looking at engraving on paper. A couple images I’ve held it up to a red light to show how thin the engraving got, almost like lace.
