Download the engraving files and adjust the artwork accordingly. A handy tip is to scan in your napkin ring and create a template for your engraving. You can use the Red Dot Pointer on your Epilog Laser to preview the area to make sure the napkin ring is perfectly positioned on your engraving table.
To Create the Napkin Ring Outline: Scan the napkin ring and bring it into your graphic design software. Create an outline around the napkin ring for the laser to follow using your software's pen tool. With the lid of your laser open and Red Dot Pointer turned on, send the vector outline to the laser and adjust your napkin ring's positioning on the engraving table.
This will give you a visual indicator of where the design will engrave - adjust the template accordingly for each napkin ring. When you're happy with the placement, send the raster job over.
