Line art to clean vector for print and production

The moment happens when a freelance illustrator or small print shop scans a hand-drawn logo or sketch, drops it into their vector software, runs auto-trace, and gets back a jagged mess of anchor points they don't know how to fix. They needed a print-ready file an hour ago. Nobody has solved this specific case well because the major vector editors have no incentive to — their auto-trace feature exists to check a box, not to solve the workflow. Their actual business is selling subscriptions to professionals who already know how to clean up the output manually. The non-expert user who needs clean output is not who those tools were designed for.

What users describe is a two-part failure: the conversion itself loses or blurs fine lines ('the vector feature can lose lines when cleaning line-art'), and then the resulting file isn't print-ready ('creating print ready vectors that don't always come in as they should'). These aren't separate problems — they're one pipeline that breaks in two places.

The gap that persists is structural: auto-trace inside Illustrator or Affinity outputs raw path data, then leaves the user alone with it. There's no step that asks 'what is this going to be used for?' and adjusts the output accordingly — a sticker cut file needs different path treatment than a large-format banner. Users end up bouncing between their main tool and secondary apps trying to find a workaround ('usually I have to find another way around the issue').

This is a business because the need recurs every time a new project comes in. A print shop or freelancer who handles five logo conversions a week is losing real billable time on each one. The cost is concrete: either hours of manual cleanup, or a client deliverable that comes back rejected by the print vendor because the file isn't production-ready.

What to build

Build a web-based conversion pipeline that accepts a scanned or photographed image, applies ML-based line cleaning before vectorization, and outputs a print-ready SVG or PDF with anchor point counts and stroke weights appropriate for the selected output type (sticker cut, screen print, large format) — no vector editor required.

Where to start

Start with screen printing shops specifically — they receive client-supplied JPG logos constantly, they have a clear and recurring production deadline, and a rejected file costs them a reprint. They'll pay immediately if you can demonstrably reduce file rejection rates.

The hard part

The hardest technical trade-off is tuning the line-cleaning step: too aggressive and you alter the artist's original lines in ways they'll object to, too conservative and you're back to the same noisy output users already get. Getting that threshold right requires a large labeled dataset of before/after conversions, which you don't have on day one.

How it makes money

Pay-per-conversion for low volume users (e.g. $1–2 per file), with a flat monthly subscription for shops doing more than 20 files per month — subscription tier also unlocks batch upload.
