1. How Laser Photo Engraving Works

Unlike printing, laser engraving interprets photos by brightness levels. It uses a technique called raster engraving, where the laser scans line-by-line, adjusting power based on each pixel's brightness.

• Bright areas → Lower power → Lighter engraving

• Dark areas → Higher power → Deeper, darker engraving

Think of it like creating a dot-matrix print—but using heat to burn or mark material instead of ink.

2. Preparing Your Photo: Resolution, Contrast, and Editing

Good photo engraving starts with smart photo editing.

• Convert to Grayscale: Always change your color image into black and white.

• Adjust Contrast: Boost contrast moderately. Too much can lose details; too little makes the engraving look muddy.

• Choose Between Dithering and Grayscale:

  • Dithering: Creates shading with dot patterns—best for wood and textured materials.

  • Grayscale: Smooth shading with 256 brightness levels—great for leather, acrylic, and coated metals.

Ideal Settings:

• Resolution: Minimum 300 DPI

• Size: Match the final engraving size 1:1 during editing

Tip: Always preview how the photo looks in grayscale before engraving!

3. Best File Formats for Photo Engraving

Choosing the right file format affects the final quality.

Format	Characteristics	Recommendation
BMP	Uncompressed, no pixel loss	Highly recommended ✅
PNG	Lossless compression, supports transparency	Good choice ✅
JPG	Compressed, may introduce noise	Not recommended ❌

Stick to BMP or PNG for the best precision.

4. Setting Laser Power and Speed for Engraving

The magic balance:

• Power: Determines how deeply the laser burns

• Speed: Affects how much exposure the material gets

Example Starting Point (Birch Wood, 40W CO2 Laser)

• Power: 25–50%

• Speed: 200–400 mm/s

• DPI: 300–600 DPI

Important: Always run a small test engrave before committing to your final piece!

5. Best Materials for Photo Engraving

Material	Characteristics	Suitability
Birch Wood	Smooth grain, light color	Excellent ✅✅✅
MDF	Uniform tone but smoky smell	Good ✅✅
Marble	Luxurious look, non-reflective	Good ✅✅
Leather	Natural tone change, less detail	Moderate ✅
Metal (Coated)	High resolution possible with fiber laser	Good ✅✅

Best for beginners: Birch plywood or MDF.

6. Common Mistakes and How to Avoid Them

Mistake	Cause	Solution
Using a complex photo	Background noise confuses the laser	Choose close-up, simple images
Low contrast	Blurry engraving	Boost contrast during editing
High power + high speed	Lost details and burns	Lower power, moderate speed
Low resolution images	Pixelated results	Use high-resolution originals
