Prepare Photos for Wood Laser Engraving
Wood has limited and variable tonal response. Prepare the image around that reality before you send it to the laser.
Built around real laser preparation
PixGrav focuses on the image-processing stage before production, helping you create cleaner, more controlled artwork for engraving workflows.
Control midtones
Wood can lose subtle tonal differences, so useful contrast matters more than screen-perfect appearance.
Match detail to material
Avoid processing detail finer than the grain, spot size or engraving resolution can reproduce.
Test efficiently
Use a consistent image-preparation workflow before tuning machine speed and power.
Workflow
Keep image preparation structured and repeatable before you tune the machine itself.
Why prepare the image first?
Laser speed, power, frequency, focus and material response cannot compensate for a poorly prepared source image. A controlled preprocessing stage makes testing easier because the artwork stays consistent while machine parameters change.
Frequently asked questions
What DPI should I use on wood?
It depends on the machine, lens and material. A practical workflow is to test around the resolution your laser spot and wood grain can actually reproduce.
Why do some photos look muddy on wood?
Insufficient tonal separation, excessive resolution, poor focus or material variation can all compress detail.
Should I invert the image?
Usually not for ordinary wood photo engraving, unless your specific material and process require reversed tonal behavior.
