Pepart

A print-on-demand storefront where the on-screen preview is the print, exactly — down to the crop.

Preview = the print

Framed posters, made on demand

Print-ready render of the buyer’s crop

Preview = print

No crop drift, by design

Automated

Payment → render → Printful order

— The challenge

The problem

Print-on-demand has a trust problem: customers can't see what they'll actually receive, and a crop that drifts by a few pixels between preview and print means a refund and a reprint. Pepart needed the preview to be the print — exactly.

— What we built

The solution

Real-time 3D frame configurator

Customers choose frame size and colour and preview the poster in 3D or staged in a room, with a 2D canvas fallback for browsers without WebGL.

A crop that becomes the print

The buyer’s pan-and-zoom crop is captured once and re-rendered server-side at 300 DPI — the same crop math drives the preview and the print file, so there is no drift.

Automated fulfilment

Payment triggers a print-file render and a Printful order automatically; mockups, shipping rates, and tracking all flow back from Printful.

— The outcome

What changed

The pipeline that draws the preview is the pipeline that renders the print, at 300 DPI — so what a customer crops on screen is exactly what arrives framed, and every order flows to Printful without a human in the loop.
