How important is it to engrave at a high resolution?

It depends on the graphic and the material. Print quality, commonly referred to as resolution, can greatly impact your engraving time. Resolution is expressed in dots per inch (DPI) and is determined by the number of lines or dots that are engraved for every inch of movement. It’s a small tweak, but just taking your engraving resolution down from 600 to 400 can reduce cycle times by up to 30 percent, and processing at 300 DPI could mean half the cycle time.
