# Configuration
> Every setting on a Gang Sheet design in the dashboard: film and billing, nesting, quality floor, uploads, design tools and the pricing selectors — what each does and its default.
A Gang Sheet design is configuration, not a canvas: it tells the builder
what film the shop runs, how the sheet is billed, how pieces are packed
and what customers may do to their artwork. Open the design in the
dashboard to edit it; the panel is split into the sections below.
Projects take a **snapshot** of these settings when a customer starts
building. Changing a setting affects new projects only — a sheet a
customer saved on 22" film stays on 22" film when they resume it.
## Builder mode
| Setting | What it does | Default |
| ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------- |
| **Builder mode** | *Gang sheet* — the customer builds the sheet and pays for the film length used. *Transfers by size* — the customer sets a print size and copy count per design and pays by print area; the shop nests the transfers (the customer never sees a sheet). | Gang sheet |
Most of the settings below apply to both modes. Transfers by size hides
the ones that only make sense for a customer-built sheet (billing
increment, customer nesting), and prices by area instead of length — see
[Pricing](/docs/gangsheet/pricing).
## Film and billing
| Setting | What it does | Default |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- |
| **Unit** | The measurement unit for every size on this panel and in the builder. Switching converts the values. | Inches |
| **Film width** | The width of the film roll. Pieces nest across this. | 22 in |
| **Max sheet length** | The longest sheet one order can use. A bigger order overflows onto a second sheet, which the customer sees as *Sheet 2*. | 120 in |
| **Min billable length** | The shortest sheet a customer can order. A pack shorter than this is padded to it, and the summary shows the padding as free length. | 3 in |
| **Bill per** | How the used length turns into the number sent to your store: per inch, per foot (or per centimeter for metric units), or fixed sheet lengths. The used length is rounded **up** to the next increment. | Inch |
## Nesting
| Setting | What it does | Default |
| ------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- |
| **Gap between pieces** | The minimum space the packer keeps between transfers so they can be cut apart. | 0.125 in |
| **Sheet edge padding** | A keep-out margin along the film edges. | 0 |
| **Allow rotating pieces** | The packer may turn pieces sideways to save film. Customers can switch this off per design in the list (*May rotate*). | On |
| **Customer may adjust nesting** | Shows the gap and rotation controls in the builder's top bar so customers can change them for their sheet. | On |
| **Customer may adjust pieces on the sheet** | Lets customers select, move and resize pieces directly on the sheet. A resize on the sheet updates the design's size in the list and re-checks its DPI. Off keeps the sheet view-only: every size comes from the design list, and the auto-nest owns the layout. | On |
Leave **adjust pieces on the sheet** off if you want a layout you can
trust blindly. The nest is validated on our servers before checkout
either way, so a customer nudge that crosses the gap is caught, but a
view-only sheet never needs the check.
## Quality
| Setting | What it does | Default |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------- | ------- |
| **Minimum DPI** | Artwork below this resolution at its printed size is flagged in the list, on the sheet and in the summary, with the largest size that would pass. | 300 |
| **Low DPI blocks checkout** | On: Preview & Save stays disabled until every design meets the floor. Off: the warning shows but the customer can still order. | On |
Text pieces and SVG graphics from the gallery are vectors and never carry
a DPI verdict.
## Uploads
| Setting | What it does | Default |
| ------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------- | ------- |
| **Remove background** | Shows a *Remove background* switch on each uploaded design. Uploads that are already transparent get the switch disabled — there is nothing to cut. | On |
| **Allow image effects** | Shows a *Halftone* switch per design, which screens the piece at print resolution. | On |
| **Upscale small images** | Upscales low-resolution uploads to help them meet the DPI floor. | Off |
| **Welcome message** | The text shown in the empty design list before the first upload. Leave it blank for the default. | — |
## Design tools
Each switch adds a control to the builder. All four are on by default.
| Setting | What the customer gets |
| -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Add text** | An *Add Text* button: type text, pick a font from your typography catalog, set the height, colour and an optional outline. The text is placed as a vector and prints sharp at any size. |
| **Gallery** | A *Gallery* button listing the graphics folders this design's profiles allow. Raster graphics behave like uploads; SVG graphics stay vector. |
| **Edit image** | An *Edit Image* button on uploaded and gallery rasters: rectangle or circle crop, brightness and contrast. |
| **Outline** | An *Outline* button that adds a keyline around a design — a white outline for dark garments, for instance. |
See [Design tools](/docs/gangsheet/design-tools) for how each behaves.
## Pricing
Print.App does not price the sheet; your store does. These two fields
connect the builder to the product page.
| Setting | What it does | Default |
| ------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- |
| **Price target on the product page** | Where the billable value is sent while the customer designs. Empty disables the push. `po:dimensions` feeds the Print Options widget with the film width and used length. Any other value is a CSS selector of an input on your product page, which receives the billable length in your billing unit (or the sheet count for fixed sheets). In Transfers-by-size mode the **total copy count** is sent instead, to `po:quantity` or to the selector you name. | — |
| **Price display source** | Shows the product page's live price inside the builder. `po:price` reads the Print Options widget's total; otherwise a CSS selector of the theme's price element. Empty hides the price in the builder. | — |
[Pricing](/docs/gangsheet/pricing) walks through each path with numbers.
