Understanding Laser Cutting Requirements
Laser cutters interpret vector files differently than printers or screens. The machine follows paths exactly, so your file preparation directly determines project success.
How Laser Cutters Read Vector Files
Cut vs. Engrave
Laser operations depend on line properties:
Line Settings:
CUT: Hairline stroke (0.001" or less)
ENGRAVE: Any fill or thicker stroke
SCORE: Light power, vector path
Color Mapping
Many lasers use colors for settings:

Document Settings
Recommended Setup:
Document size: Match material size
Units: Inches or millimeters
Color mode: RGB
Export format: SVG or DXF
Organizing Layers
Separate operations by layer:

Paper and Cardboard
Paper Settings:
Cardstock: Low power, high speed
Corrugated: Medium power, multiple passes
Matboard: Test carefully
Vector considerations:
Kerf Compensation
What is Kerf?
The laser beam has width, removing material:
Typical Kerf Values:
Wood: 0.15-0.25mm
Acrylic: 0.1-0.2mm
Paper: ~0.1mm
