The Maker's Guide to Going from Photo to Engraving

Every laser engraving job — whether it’s a pet portrait on slate, a wedding gift on walnut, or a hundred-piece order of leather keyrings — starts with the same question: how do I turn this image into something the laser can actually burn well?

This guide walks through that workflow end-to-end, in the order you’ll actually use it.

Step 1: Start with the right image

Most engraving disappointments are baked in before the file ever reaches the laser. The single biggest predictor of a good result is the quality of the source photo. When a customer sends you something, check for:

• Good lighting. Soft, even light. No hard shadow cutting across the face. No backlight turning the subject into a silhouette.
• Sharp focus. A blurry photo cannot be sharpened back to crisp detail — the information just isn’t there.
• Clear separation between subject and background. A black dog on a dark sofa is a nightmare. Ask for a re-shoot if you can.
• Resolution. At minimum 1500×1500 px for a 100 mm engrave. More is better.

Don’t be afraid to politely ask for a better photo. Two minutes of awkward chat saves you an hour of fighting bad input.

Step 2: Remove or simplify the background

For portraits (people, pets, products), the background almost always has to go. The laser doesn’t know that the floral wallpaper isn’t important — it will engrave every petal at full attention.

Browser-based background removal (the kind that runs locally on your machine using ONNX models) is now accurate enough for 90% of photos. Refine the mask manually for hair, fur, and edges where the model gets confused.

Step 3: Decide raster or vector

This is the fork in the road. Choose based on the artwork:

Use raster (PNG) when…	Use vector (SVG) when…
It’s a photo, portrait, or anything with continuous tones	It’s a logo, line drawing, or text
You want shading and gradients	You want crisp edges and scalability
You’re engraving on wood, leather, or slate	You’re cutting, scoring, or doing a single-tone fill

Step 4: Prep the raster (photos)

For raster work, three adjustments make the biggest difference:

1. Midtone lift. Raise the gamma slightly. Most photos look perfect on screen but engrave dark and muddy because midtones go in too low.
2. Contrast curve. A gentle S-curve gives the laser something to work with: punchy shadows, clean highlights.
3. Dithering. Convert grayscale to a dot pattern before the laser does. Jarvis or Stucki dithers produce the most natural-looking engraves on wood and leather.

Step 5: Prep the vector (logos, line art)

Vector prep is mostly about cleanliness:

• Remove stray nodes and duplicate paths.
• Make sure fills are properly closed shapes, not loose strokes.
• Limit detail to what the laser can resolve — lines thinner than 0.1 mm on most diodes will disappear.
• Keep colours intentional: many laser softwares (LightBurn especially) use stroke colour as a layer assignment.

Step 6: Preview before you burn

A mockup is worth a hundred test burns. Before you commit any material:

• Overlay your design on a photo of the actual product (wood blank, leather patch, slate coaster).
• Check sizing — what looks fine on a screen often turns out tiny in real life.
• Check that important detail (eyes, signatures, brand marks) isn’t crammed near edges.

Step 7: Run a corner test

On any new material or unfamiliar customer photo, engrave a small (15×15 mm) corner of the design first. Look at it under the kind of light the customer will see it under — daylight or warm bulb, not your phone torch. Adjust power, speed, and gamma based on that real-world result.

Step 8: Batching for repeat orders

If you’re running a shop, the productivity unlock is batching:

• Group orders by material and thickness. One focus, one set of settings, ten pieces.
• Build a single LightBurn or design file with a tiled grid of all the orders. The laser engraves them in one pass.
• Use masking tape across the whole bed at once, then peel and pack.

A well-batched evening can double your output without buying a second machine.

Step 9: Pricing what you make

One mistake most new makers make is pricing only the material. A more honest formula:

Price = (material cost × 3) + (run time in minutes × your hourly rate / 60) + design time

If a piece is genuinely custom (a one-off portrait), add a flat “custom artwork” fee on top. Your time prepping the photo is real labour, even if the laser does the burning.

Step 10: Keep a finished-work log

The most underrated habit: photograph every finished piece in good light and save it, with the material, settings, machine, and a screenshot of the prep file. Six months in, you’ll have a private cookbook nobody else has, and every new order gets faster to quote.

Tools that fit this workflow

You can stitch this whole pipeline together with Photopea, Inkscape, an online background remover, and a vectoriser. Or you can use a single tool built around this exact workflow.

EngraveIQ is built end-to-end for makers: upload a photo, choose a style, get an engraving-ready PNG or SVG, preview it on a mockup of your material, look up laser settings for your machine, and download. It’s the workflow above, compressed into a couple of clicks — without giving up the manual control you need on the edge cases.
