Using the Arnold Prints Gang Sheet Builder: A Step-by-Step Walkthrough

Our online gang sheet builder lets you lay out your own DTF transfers, see exactly how they fit on the roll, and order without emailing files back and forth. This walkthrough covers every step, from prepping artwork to checkout, plus the habits that keep your transfers looking sharp and your film costs down.

You can open the builder any time at our DTF gang sheet page. Everything you build there is printed as a custom DTF gang sheet roll, 12.3 inches wide, from 24 to 300 inches long.

Step 1: Prep your artwork before you open the builder

The builder can only print what you give it, so five minutes of prep saves a reprint.

• File type: PNG with a transparent background is best. Anything that is not part of the design should be fully transparent, not white.
• Resolution: 300 DPI at the size you plan to print. 150 DPI is the absolute floor for clean results.
• Size: Design at actual print size, for example 11 inches wide for an adult full front or about 3.5-4 inches for a left chest.
• Colors: Remove faint drop shadows, glows, and semi-transparent edges unless you want them printed as a light haze with white underneath.

If your file has a baked-in white or checkerboard background, or soft edges that will print as a halo, our paid DTF Prep Pro service can clean it up into a print-ready file. You can also read our guide to prepping DTF files: halftones, knockouts and white ink.

Step 2: Upload your designs

Open the builder and upload your artwork files. You can add several designs at once. If you are signed in to your Arnold Prints account, your uploads are saved to your artwork library so you can find them again on your next order instead of digging through old emails.

Pay attention to any warning the builder shows after upload, such as a low-resolution or background warning. Those warnings exist because the problem will show up on the shirt, not just on screen.

Step 3: Choose your roll length

Pick a starting length based on how much art you have. Not sure? Start shorter, place your designs, and step up to the next length if you run out of room. Longer rolls cost less per foot, so if you are close to the next size, it is often worth filling it with extra copies or spare small logos.

Step 4: Place, size, and duplicate

Drag designs onto the sheet, then set each one to its final print size. A few tips:

• Size in inches, not by eye. Use the size controls so a left chest is the same on every shirt.
• Duplicate for quantity. Need 24 left-chest logos? Place one, then duplicate it instead of uploading it 24 times.
• Leave a little space. About a quarter inch between designs keeps cutting clean.
• Nest mixed sizes. Tuck sleeve prints, neck tags, and small logos into the gaps around large designs.
• Rotate when it helps. Turning a tall design sideways can free up a row.

Use the zoom and fit views to check the whole roll and then inspect details up close. Our article on building the perfect DTF gang sheet goes deeper on layout.

Step 5: Review before you approve

Zoom in on every design one more time and check:

1. Spelling on names, dates, and phone numbers
2. That every design is at the correct size
3. That backgrounds are transparent and edges are clean
4. That you have the right quantity of each design, plus a few spares
5. That light-colored art will read on the garment color you are pressing

Then check the approval box. We print exactly what is on the sheet, so your approval confirms the layout, sizes, and artwork are correct. The builder makes the approval box hard to miss on purpose.

Step 6: Add to cart and check out

Once approved, add the sheet to your cart and check out like any other order. Gang sheet rolls are typically ready in 1-2 business days. Choose local pickup at our Westlake location to skip shipping, and we will text you when it is ready.

Step 7: Press it right

When your roll arrives, cut out the transfers and press at 300-320°F for 12-15 seconds with medium, even pressure, after a quick pre-press. Our rolls are hot peel, and a 5-10 second finishing press under parchment or Teflon gives the softest, most durable result. An alignment ruler set helps every logo land in the same spot from shirt to shirt.

Common builder mistakes to avoid

• Stretching small images up. Enlarging a low-resolution file past its native size makes it blurry when printed.
• White boxes around designs. A white background prints as a white rectangle. Remove it first.
• Leaving film empty. Empty space costs the same as printed space. Fill it with extras.
• Skipping the zoom check. Typos and jagged edges are much easier to catch before printing.

Frequently asked questions

Do I need an account to use the gang sheet builder?

You can build a sheet without one, but signing in saves your uploads to your artwork library so reorders are faster.

What file should I upload?

A PNG with a transparent background at 300 DPI, sized to the actual print dimensions, gives the best results.

Can you fix my artwork for me?

Yes. DTF Prep Pro is a paid file-prep service that cleans backgrounds and edges into a print-ready file. For bigger redraws, contact us for a quote.

What happens after I approve?

We print exactly what you approved. Double-check spelling, sizes, and quantities before checking the approval box.
