Free DTF & Sublimation Gang Sheet Builder
Auto-nest multiple vector SVGs and transparent PNGs onto standard 22-inch DTF rolls (22×24, 22×36, 22×60, 22×120) or 8.5×11 and 13×19 sublimation sheets. Minimize film waste, check cutting clearances, mirror for heat press transfers, and download 300 DPI master print files with zero server uploads.
How the Free DTF & Sublimation Gang Sheet Builder Works
Direct-to-Film (DTF) transfer printing and wide-format dye-sublimation are the most cost-effective methods for apparel decorators, Etsy shop owners, and custom crafters to produce vibrant full-color designs. However, buying PET film rolls or 13×19 sublimation sheets by the square foot means that unused blank space is wasted money.
This browser application implements a high-performance 2D rectangular shelf-packing algorithm combined with hardware-accelerated canvas rendering. When you add vector SVGs or transparent PNGs, the auto-nester calculates the minimum bounding box for each design, accounts for your designated cutting margins (0.25" to 0.50"), and packs designs tightly from top to bottom. It dynamically tests both 0° and 90° orientations to maximize film density while preventing overlapping graphics.
100% In-Browser Privacy
Your client graphics, custom logos, and purchased SVGs are rendered locally using HTML5 Canvas and FileReader APIs. Files never leave your computer or upload to external cloud servers.
Dual Native Master Exports
Export a crystal-clear 300 DPI transparent PNG for immediate raster printing, or download a Master Vector SVG scaled 1:1 in exact inches for Illustrator, Corel, or RIP software.
Live Roll Utilization Tracking
See exactly how many inches of film your job requires. If your graphics only consume 38 inches of a 60-inch roll, you can trim the roll early and save the remainder for your next print run.
Step-by-Step Instructions: Building a Flawless Gang Sheet
- Configure Sheet or Roll Dimensions: Choose your print setup from the preset list (such as a 22" × 60" DTF roll, 13" × 19" Super B sublimation paper, or 8.5" × 11" US Letter). You can also enter custom inch widths and heights for specialized roll widths (such as 13" or 24").
- Set Edge Margin and Cutting Spacing: Keep edge margins at 0.25" to 0.35" so that printer pinch rollers do not scrape against printed ink. Set item spacing to at least 0.25" to ensure you have adequate white space to slice apart transfers with scissors or rotary shears without cutting into designs.
- Upload or Select Artwork: Drag and drop multiple SVGs or transparent PNGs into the upload zone, or click the 1-click sample buttons. Specify target physical dimensions in inches for each graphic (e.g. 10.5" for adult front prints, 3.5" for chest pocket logos, or 2.5" for sleeve badges) and enter the required copy quantity.
- Auto-Nest or Fine-Tune Manually: Click Auto-Nest All Graphics to calculate the densest packing arrangement. You can also click and drag any graphic directly on the visual canvas to reorder items, rotate pieces 90 degrees, or duplicate graphics to fill remaining gaps.
- Export for Print: For sublimation transfers, check the Mirror Horizontally box so your lettering reads correctly after heat pressing. Click Download 300 DPI Transparent PNG to generate a print-ready raster file, or Download Master Vector SVG for infinite resolution vector processing in LightBurn or CADlink.

Best Practices for Cricut, Silhouette, Laser Cutters & Sublimation
1. Direct-to-Film (DTF) Heat Press Application
DTF transfers adhere to virtually all fabric blends, including 100% cotton, 100% polyester, triblends, canvas, and nylon. For standard hot-melt TPU adhesive powder, pre-press your garment for 5 seconds to remove moisture and wrinkles. Press the DTF transfer at 300°F to 320°F (150°C to 160°C) for 12 to 15 seconds with medium-to-firm pressure (60 PSI). Allow the film to cool completely for cold-peel film (or peel immediately if using instant-hot-peel PET), then cover with parchment or a Teflon sheet and post-press for 5 seconds to seal the transfer into the fabric weave.
2. Dye-Sublimation on 13×19 and Letter Sheets
Sublimation ink permanently bonds with polyester polymers through gas dye diffusion. For 100% polyester shirts, tumblers, and mousepads, always enable the Mirror Horizontally toggle in this builder. Press sublimation paper at 385°F to 400°F (195°C to 205°C) for 45 to 60 seconds under firm, uniform pressure. Use butcher paper or blowout paper on both sides to prevent stray sublimation gas from staining your heat press platen.
3. Cricut & Silhouette Multi-Up Print Then Cut
If you are creating printable vinyl stickers or light heat transfer sheets on a cutting plotter, use this builder to nest your graphics across an 8.5" × 11" sheet. The consistent spacing prevents blade tracking errors, while the master vector SVG export can be imported into Cricut Design Space or Silhouette Studio with exact registration coordinates.
4. Laser Cutting & Acrylic Blank Nesting
When cutting multiple acrylic charms, wood keychains, or leather patches on a CO2 or diode laser (such as an xTool P2 or Glowforge), you can use this gang sheet builder to nest your vector SVGs onto standard 12" × 20" or 16" × 24" sheets of Baltic birch plywood or acrylic. Download the Master Vector SVG to preserve clean hair-line vector cut paths without any pixel rasterization.
