Image Resolution vs Line Interval: Stop Chasing Impossible DPI
Match source detail and scan spacing to the physical laser spot and material instead of assuming more DPI always means more detail.
Trace Image: Convert Bitmap Artwork into Editable Vectors
Use tracing for logos and line artwork while controlling threshold and cleanup so the result does not become a forest of unnecessary nodes.
Threshold vs Grayscale: Choose the Right Image Interpretation
Know when a black/white decision is appropriate and when preserving tonal variation is essential to the engraving.
Dithering Modes: Turning Gray Tones into Laser-Friendly Dot Patterns
Understand why different dithering algorithms distribute on/off dots differently and why there is no single best mode for every photo or material.
Adjust Image: Brightness, Contrast and Gamma
Use LightBurn's image controls to shape tonal information before engraving without confusing image processing with laser power.
Image Mode Layer Settings: What Belongs to the Layer and What Belongs to the Image
Separate Image Mode laser settings from per-image processing controls so a change to one image does not unexpectedly affect everything on its layer.
Image Engraving Workflow: Five Decisions That Matter
A practical order for preparing photo engravings: material response, Speed/Power, interval, image processing and Preview.
Line Interval and DPI: Why More DPI Is Not Always Better
Learn what scan-line spacing changes, why excessive density can hurt quality, and how the Interval Test finds a practical value.
