How to read it
Burn the whole card at one power and speed. The best DPI is the lowest one whose patch looks solid with no visible lines: higher DPIs only overlap and over-burn.
Fine lines show the narrowest stroke your beam holds; small text shows the smallest legible lettering. Both are drawn at the file resolution.
