Your customers build the gang sheet. You print it.
SheetGangster puts a gang sheet builder on your Shopify store. Customers upload their artwork, lay it out and check it on one page. You set what a sheet is and what it costs, and the order lands in your queue with the print file.
Free plan included. Paid plans have a 14-day free trial, billed through Shopify.
A real sheet, as built in the app on our own store.
Three steps, and the third one is yours.
Add the button
Install from the App Store, drop the SheetGangster block on any page, and set your sheet width, lengths and rates in Settings.
Customers build
They upload, lay out and check their sheet on one page, see the price change as it grows, and add it to the cart like any product.
You print
The order arrives in your queue with a print ready file at the exact length. Print it, mark it done, move on.
Everything a gang sheet shop needs, in one app.
Built for shops that print DTF transfers and want customers to do the layout, without giving up control of what a sheet is or what it costs.
Customers lay out their own sheet
Upload artwork, then drag, resize, rotate, crop, copy in a grid and pack tightly. No account needed; signing in keeps the sheet for later.
Auto build from sizes and quantities
A customer types the sizes and how many of each, and the sheet lays itself out at the shortest length that fits.
Your sheet, your rules
Width, length range, rounding step and safe margin match what you print on. The customer never changes them.
Priced the way you sell
By the square inch at your rate with volume breaks on longer sheets, or as a list of named sizes you price yourself. The price is worked out on our side and locked at checkout.
Print types such as UV DTF
Up to 10 kinds of sheet, each with its own width, rates and colour. Customers pick one before they build, or you point a button at one.
Vectorization as a service
Offer hand redrawn vector art at your fee, on a sheet or as its own product with an upload box on the product page.
A print queue that sorts itself
Orders land in a queue ordered by what needs doing. Every sheet downloads as a print ready PDF or PNG at the exact length ordered.
Every order checked
Each gang sheet line is checked against the frozen design before it can be fulfilled, so an edited cart cannot print at the wrong price.
Nothing to host
Install from the Shopify App Store, add one theme block, and it runs. Artwork is stored for you, within the plan's allowance.
Problems found before they cost you film.
Every upload is checked for the things that spoil a print: a background that should not be there, empty space, stray specks, soft edges, see-through pixels, glow and low resolution. Each one comes with a fix the customer applies in one click.
- Background removalA colour remover and an AI remover, both with smooth cut edges. Every plan.
- Crop empty spaceTrims the blank border so the customer pays for artwork, not air.
- Preview on any colourSee the design on black, white or the garment colour before it prints.
- Stray specks and see-through edgesBasic and upFinds the dust and the half transparent pixels that print as grey halos, and removes them.
- Solid edges and glow removalBasic and upHardens soft edges and strips the glow a screenshot or a JPEG leaves behind.
- Largest sharp sizeBasic and upTells the customer the biggest size a soft image can print at and offers it in one click.
- AI upscalingPremium and upRedraws a small image at up to four times its size, so a 400 pixel logo can print at 10 inches.
Print check on three uploads. One has a white background; the fix is already ticked.
We run a DTF shop. We built SheetGangster because laying out other people's gang sheets by hand was the slowest part of every order, and the tools we tried either gave us no say over the sheet or no say over the price.
- Runs on our own store first. Every release is used on real orders before it ships.
- Built around how a sheet is actually printed: width, rounding step, safe margin, film length.
- Nothing is rendered on our servers. The print file is assembled in the browser, at full resolution.
- Support is a printer answering, not a ticket queue.
Start free. Grow into the rest.

SheetGangster runs as a Shopify app. Printing on another platform? We are open to integrating with it; tell us what you run and we will talk.
The ones we get asked.
Does it work with my theme?
Yes. The launcher is a theme app block, so it goes on any Online Store 2.0 theme through the theme editor, styled to match your buttons. The builder itself opens as its own page on your domain.
Do customers need an account?
No. Anyone can build and order a sheet. A signed-in customer can also save sheets and come back to them.
Where does the printing happen?
On your equipment. SheetGangster produces the print file; you print and ship. There is no fulfilment partner in the middle.
Can I use it outside Shopify?
Not yet. SheetGangster runs as a Shopify app today. If you print on another platform and want it there, tell us on the Support page; we are open to integrations.
What does it cost?
There is a free plan with the whole builder, print check and the queue. The paid plans raise the limits and add tools such as print types and AI upscaling, with a 14-day free trial, billed through Shopify. No plan takes a percentage of a sale.
