How to turn a photo into plasma-cut art

A photo of a dog, a truck or a buck in the field won’t trace straight into steel: it’s full of soft shading and background. To cut it, it has to become bold two-tone art first. Here are the steps, from free and fast to fully redrawn.

1. Start with the best photo you have

• A clear side-on outline (a silhouette pose) makes the best cut art. Faces straight-on are hardest.
• A plain background (sky, wall, snow) is far easier to remove than a busy one.
• Use the full-size original, not a screenshot or thumbnail.

2. Clean it up: even lighting, no grain, sharp edges

Photos of paper sketches have shadows and grey paper; phone photos have grain. Flatten the lighting, remove the grain, sharpen the edges, and snap everything to pure black and white. Then remove the background so only the subject is left.

3. Or have AI redraw it as a stencil

For busy photos, an AI redraw is faster than hand-tracing: it keeps the subject’s outline and pose but draws it as solid black shapes with no background. Always check the result against the original, because AI can change small details such as antler points or lettering.

4. Make it cuttable

• Islands (pieces floating inside holes) need bridges or they fall out.
• Thin bits such as whiskers, fur detail and fine grass burn away: thicken them or remove them.
• Specks are extra pierces and loose parts: delete them.
• For a layered sign, split the picture into 2–3 tones and cut each tone as its own piece to stack.

5. Size, test and cut

Set the finished size, check the smallest holes and bridges against your plate thickness, and cut a small test first. (See the kerf chart and the image to DXF guide.)
