How to Prepare Files for Laser Cutting (and Avoid Rejections)
The Key to a Smooth Cutting Process
Submitting a file for laser cutting seems simple—until it gets rejected or produces unexpected results. The truth is that laser cutters require precision-ready vector files, not raster or photo-based images. A few small setup mistakes can cause wasted material, off-measure cuts, or even halted production.
Knowing how to properly prepare your file saves time, cost, and frustration—and ensures your project cuts perfectly the first time.
Use the Right File Type
The most important step is submitting a vector file, not a raster image. Accepted formats are:
AI (Adobe Illustrator)
DXF (AutoCAD)
PDF (vector-exported only)
Raster formats like JPEG, PNG, or TIFF can’t be used for cutting because they’re made of pixels, not paths. Even if the image looks sharp on-screen, a laser cutter can’t follow it as a defined path.
Keep Your Design Clean and Organized
Convert all text to outlines
Fonts must be outlined so the cutter reads them as shapes, not editable text.Use consistent line colors and weights
Typically, red for cuts and blue for engraves. Avoid extra layers or unneeded colors.Remove duplicates and hidden geometry
Overlapping lines or hidden objects can cause double cuts and material damage.Check scale and dimensions
Always design at 1:1 scale (actual size) and verify units—preferably in inches or millimeters.Ensure closed paths
Open vector paths cause incomplete cuts. Every shape should form a closed loop.
Keep File Complexity Reasonable
Too many small nodes or micro details can slow processing time and overheat materials. Simplify complex curves and eliminate unnecessary anchor points before exporting.
If you’re combining engraving and cutting in one file, make sure:
Engraving areas are separate from cut lines.
Engraving power and speed settings are balanced for the chosen material.
Avoid Common Mistakes
Submitting a photo or logo saved as a PDF (still raster inside)
Forgetting to outline text
Misaligned layers or inconsistent stroke colors
Artwork with embedded images instead of paths
Overlapping duplicate lines on shared edges
How American Laser Cutter Helps
Our team reviews every submitted file for compatibility before production. If there’s an issue, we’ll notify you immediately and guide you through the corrections—ensuring your design meets cutting requirements without delay.
We cut directly from AI, DXF, and vector PDF files, and we can handle both customer-supplied materials or in-house stock. Every project runs on professional CO₂ laser systems calibrated for accuracy and repeatability.
Conclusion
Proper file preparation is the foundation of a successful laser cutting project. A clean, organized vector file means faster turnaround, lower cost, and perfect precision.
