Gang Sheet Builder

The Shopify gang sheet builder that does the hard part.

Customers drag, drop, and arrange. Our engine cleans their files, packs the sheet, and hands you a 300 DPI print-ready PNG on every order.

How it works

Live in your store in minutes.

1

Add the builder to your store

Install the app and drop the "Build a Gang Sheet" button onto any product page with the theme extension. No code, no theme surgery.

2

Customers build their sheet

Drag-and-drop canvas with smart auto-arrange, one-click background removal, AI upscaling, and a live DPI check — so what reaches the cart is printable.

3

The file lands on the order

Checkout triggers the render pipeline: a 300 DPI PNG, stamped with the order number and QR code, attached to the Shopify order as a download link.

After the sale

One link on the order. Everything your printer needs.

Every order line carries a viewer link: each sheet named by the flow it came from, with its own View and Download buttons, the source artwork behind a click — including the original file next to any background-removed or upscaled version — and a pencil to re-edit the sheet even after purchase.

  • Print-ready download per sheet, stamped with the order number
  • Original and processed artwork side by side — never print the wrong file
  • Re-edit any sheet after purchase; customers reorder in one click
Order viewer — sheets named by flow with View, Download, and re-edit actions
Why this builder

Built different from every other gang sheet app.

Print-Perfect Image Processing

Every image runs through the best APIs money can buy. Background removal at full source resolution. AI upscaling that guarantees 300 DPI on the final print. Automatic trimming of transparent edges.

  • Background removal — clean edges, even on complex images
  • AI upscaling — crisp 300 DPI output from low-res source files
  • Live DPI badges — customers fix quality issues before checkout

Smart Auto-Arrange

MaxRects bin-packing nests every design to squeeze the most out of each sheet. Every square inch counts — less wasted film means lower cost per transfer.

  • Packs designs tight to maximize sheet coverage
  • Handles rotation and spacing automatically
  • Tall sheets split into print-ready pages automatically

Zero Variants. Zero Draft Orders. Zero Chaos.

Most gang sheet apps mint a new product variant for every single custom sheet — thousands of throwaway variants polluting your admin, a hard 2048-variant ceiling that eventually locks customers out of checkout, and cleanup jobs that delete the variants customers try to reorder later.

This builder never creates one. It sells through a single permanent product — it can even be an existing product in your store — and the exact price rides to checkout with Shopify Functions, Shopify's own native checkout pricing. Nothing minted, nothing to clean up, nothing to hit a cap.

  • No variants created — ever. No 2048-variant time bomb
  • Reorders keep working months later — no cleanup job can break them
  • Order-stamped, QR-coded PNG delivered with every order

Frequently Asked Questions

Everything you need to know about the Gang Sheet Builder. Something missing? Ask us directly.

What file formats can customers upload?
PNG, JPEG, and WebP — plus PDF. Every file runs through our processing pipeline — background removal at full resolution, AI upscaling for low-res art, and automatic trimming — before it lands on the sheet. Customers can even beam files from their phone with the built-in QR upload.
How big can a gang sheet be?
Sheets run on your printer width and grow as tall as your order needs. Oversized layouts are automatically split into multiple print-ready pages.
What do I receive when an order comes in?
A 300 DPI print-ready PNG, stamped with the order number and a QR code, delivered as a download link right on the Shopify order. No emailing files around.
Will it flood my store with products, variants, or draft orders?
No. The builder never creates product variants — it sells through a single permanent product (it can even be an existing product in your store), and the exact price is attached at checkout by Shopify Functions. No 2048-variant ceiling, no cleanup jobs, no draft orders, no admin clutter.
