How to Build a DTF Gang Sheet in Photoshop — Step-by-Step Guide

By Affordable DTF  |  File Prep Guide  |  7 min read

Photoshop is the most precise and professional tool for building DTF gang sheets. Unlike browser-based tools with size limits, Photoshop handles any sheet length, works natively in inches at 300 DPI, and gives you full control over exact placement, spacing, and quality. If you're doing regular gang sheet orders or running a print business, Photoshop is worth learning for this workflow.

This guide walks through the complete gang sheet building process in Photoshop — from canvas setup to export — with the exact settings for DTF printing.

What You'll Need

• Adobe Photoshop (any recent version)
• Your design files — PNG with transparent backgrounds at 300 DPI
• Your gang sheet dimensions — 22" wide, whatever length you need

Step 1 — Create a New Document

1. Open Photoshop and go to File → New
2. Set these document settings:
   • Width: 22 inches
   • Height: your desired sheet length (12", 24", 36", etc.)
   • Resolution: 300 pixels/inch
   • Color Mode: RGB Color, 8 bit
   • Background Contents: Transparent
3. Click Create

Step 2 — Enable Rulers and Guides

1. Go to View → Rulers (or Ctrl+R / Cmd+R) to show rulers in inches
2. Right-click the ruler and make sure it's set to Inches
3. Go to View → Snap and enable snapping for easier design placement
4. Drag guide lines from the rulers to mark your ¼" border area around the canvas edges

Step 3 — Place Your First Design

1. Go to File → Place Embedded
2. Select your first PNG design file
3. The design will appear in the canvas — click and drag to position it
4. In the top toolbar, set the W (width) to your intended print size in inches
5. Make sure the lock icon (maintain aspect ratio) is active so height scales proportionally
6. Press Enter to confirm the placement

Step 4 — Resize to Exact Print Dimensions

After placing each design, verify it's at the correct print size:

1. With the design layer selected, press Ctrl+T (Cmd+T) to enter Free Transform mode
2. In the top toolbar, change the width measurement to inches (click the % dropdown and select inches)
3. Type the exact width you want — e.g., "5 in" for a 5" design
4. Make sure the chain link (maintain aspect ratio) is active
5. Press Enter twice to confirm

Step 5 — Arrange All Designs

Repeat Step 3 and 4 for each design. As you add designs:

• Leave ¼" between every design — use your ruler guides to maintain consistent spacing
• Work across the full 22" width before moving down to the next row
• Rotate designs if needed — Ctrl+T and rotate the bounding box handle
• Use the Move tool (V) to reposition placed designs
• Use the Layers panel to select specific designs — each placed image is on its own layer

Step 6 — Check Transparency

Before exporting, verify your canvas background is truly transparent:

1. Look at the Layers panel — there should be no solid background layer (the checkerboard pattern should be visible behind your designs)
2. If there's a white background layer, click it and delete it
3. The canvas should show a grey checkerboard pattern in all empty areas

Step 7 — Export as PNG

1. Go to File → Export → Export As
2. File Format: PNG
3. Make sure Transparency is checked
4. Quality: 100% (no compression)
5. Verify the dimensions show your correct canvas size
6. Click Export All and choose your save location

Photoshop Gang Sheet Best Practices

• Save your PSD as you go — large gang sheet files can crash if you run out of memory
• Name your layers with the design name and size — makes it easy to find and edit specific designs
• Group designs by row — select all designs in a row, press Ctrl+G to group them. Makes reorganizing easier.
• Keep your PSD file for reorders — just update the design placement and re-export without rebuilding from scratch
• Use 8-bit color mode not 16-bit — DTF printing doesn't benefit from 16-bit and the file sizes are much smaller
