Make your designs hit harder in daylight and pop under blacklight. This product is for customers who already created a print-ready gang sheet and want it printed as Neon Fluorescent Transfers ultra-bright colors designed to stand out in normal lighting and become even more eye-catching under UV/blacklight (“purple light”). Fluorescent materials work by absorbing UV and re-emitting visible light, which is why they appear to “glow” under blacklight.

This is the right choice if you’re a graphic designer, apparel decorator, or DTF printer who already sized and nested your artwork into the exact layout you want. Upload your print-ready gang sheet and we’ll produce your neon/fluorescent transfers exactly as submitted.

Best-selling use cases (where neon wins)

Neon/fluorescent transfers are consistently popular for:

• Concerts, clubs, nightlife merch
• Blacklight parties & themed events
• School spirit nights, pep rallies, homecoming, dances
• Summer camps and youth events
• Brand activations and promotional apparel

Important note: “Fluorescent” vs “Glow-in-the-dark”

These are fluorescent (blacklight-reactive) transfers. Fluorescent effects generally fade immediately when the UV light is off that’s normal and expected. If you need a print that keeps glowing after lights-out, that’s a different category (phosphorescent).

Upload requirements (this is a print-ready product)

• Upload a print-ready gang sheet (we print what you submit—no re-layout)
• Match your file canvas size to the sheet size you’re ordering
• Use high-quality artwork for best edges and readability
• Keep safe margins so key elements aren’t near the trim edge

What affects the blacklight “glow”

• UV strength matters: A true blacklight/UV-A light will make fluorescent pigments react more dramatically.
• Color choice matters: Neon pink/green/yellow/orange shades are commonly the most reactive.
• Garment + lighting environment matters: Darker settings and direct UV light create the strongest effect.

Who this product is for

• Customers who already built a gang sheet and want a specialty neon print
• Brands creating event merch that stands out instantly
• Shops offering a premium neon upgrade for higher order value

Accurate Sizing (Print at Final Dimensions)

Build your artwork at the exact size you want it printed. Do not rely on scaling after upload resizing can reduce sharpness and alter layout.

Do not submit mirrored artwork unless you specifically need a reversed print. Mirrored files can cause output errors and incorrect orientation during production.

Minimum Resolution: 300 DPI (at Actual Print Size)

For crisp edges and clean detail, artwork must be 300 DPI at the final print dimensions. Lower resolution files may appear blurry, pixelated, or soft once printed and pressed.

Preferred File Types

For the most accurate print results, submit:

• Vector files (best for logos and sharp text)
  
• PDF
  
• PNG (transparent background)

These formats preserve quality and reduce the risk of unwanted artifacts.

File Preparation & Handling

Combine All Elements Into One Print File

If your design includes multiple imported graphics, merge them into a single, properly arranged file to ensure consistent spacing and continuous printing—especially for gang sheets.

Use Transparent Backgrounds (No Solid Blocks Unless Intended)

Keep backgrounds transparent whenever possible for a cleaner final application. Avoid placing artwork on a colored canvas or adding a background layer unless you want that background printed.

Convert All Text to Outlines/Paths

Convert fonts to outlines (paths/curves) before submitting. This prevents font substitution, missing characters, and layout shifts, ensuring your design prints exactly as intended.

DTF Transfer Application & Care Guide (Direct-to-Film Gang Sheets)

Before You Press

• Trim the transfer first. Using scissors, cut away any color registration strips and order/ID markings around the artwork. If left on, these extra markings can heat-bond to the garment.
  
• Preheat the garment (3–5 seconds). This removes moisture and helps the transfer bond more evenly. Let the fabric cool briefly before placing the transfer.
  

Positioning the Transfer

• Place the transfer on the garment with the white side down and the image facing up.
  
• Ensure the transfer is flat and properly aligned before pressing.
  

Press Settings (Recommended)

• Temperature: 300°F
  
• Time: 10 seconds
  
• Pressure: Medium (firm, even pressure)
  

Consistent temperature, time, and pressure are key to long-lasting adhesion especially on cotton and cotton blends.

Peel Options

Choose the peel method that matches your film type and preference:

• Hot Peel: Peel the film immediately after opening the heat press.
  
• Cold Peel: Allow the film to cool for about 60 seconds, then peel.
  

Finishing Press (Strongly Recommended)

• Cover the design with parchment paper (or a Teflon sheet, butcher paper, or tissue paper).
  
• Press again for 5 seconds using the same temperature and pressure.
  
• This step improves durability, wash resistance, and finish.
  

If the Transfer Doesn’t Release Cleanly

If the film doesn’t peel off completely:

• Lay the film back down in place, press again for a few seconds, then peel again (hot or cold depending on your method).
