The Complete Guide to DTF Printing, DTF Transfers & Gang Sheets


What Is DTF? (Direct-to-Film Printing Explained)

DTF (Direct-to-Film) is one of the fastest-growing apparel decoration methods. Instead of printing directly on garments, DTF uses a specialized DTF Printer to print designs onto DTF sheets or rolls, which are then heat-pressed onto fabric. The result?

  • Vibrant colors

  • Strong durability

  • Stretch-resistant prints

  • Compatibility with cotton, polyester, blends, nylon, and more

This flexibility has made DTF printing a top choice for small businesses, print shops, and apparel brands.

What Is a DTF Printer?

A DTF printer is a modified or purpose-built inkjet printer designed to print high-resolution artwork onto PET film using:

  • CMYK + White DTF ink

  • DTF adhesive powder

  • Heat-curing systems

High-quality DTF printers deliver sharper details, smoother gradients, and consistent white ink coverage, which is crucial for premium DTF transfers.

What Makes a Good DTF Printer?

  • Stable white ink circulation

  • Roll support for continuous printing

  • ICC color profiling for accurate colors

  • Fast curing and drying capabilities

Professional models allow for automatic shaking, powder curing, and roll-to-roll production, especially useful for gang sheets.

Understanding DTF Sheets (PET Film)

DTF sheets also called PET films are the surface where your designs are printed before transfer. They come in:

  • Single sheets (A3, A4, etc.)

  • Rolls for bulk production (13”, 24”, 32” rolls)

High-quality DTF sheets ensure:

  • Crisp prints

  • Smooth ink release

  • Strong adhesion during heat pressing

They are essential for creating long-lasting DTF transfers.

What Is DTF Transfer?

A DTF Transfer is the finished film containing your printed artwork + adhesive powder. Once cured, it becomes a ready-to-press design that can be applied to:

  • Shirts

  • Hoodies

  • Hats

  • Bags

  • Jackets

  • Hard-to-print materials

DTF transfers are popular for their:

  • Soft-hand feel

  • Excellent stretch performance

  • Long-term durability

Shops often sell DTF transfers to customers who don’t own a DTF printer.

DTF Printing Process:

Understanding the process helps you achieve the best results:

  1. Prepare artwork in CMYK, with white ink layering.

  2. Print onto DTF sheets using a DTF printer with CMYK + White.

  3. Apply hot melt powder evenly.

  4. Cure the powder with a curing oven or heat press hover.

  5. Press the transfer onto your garment.

  6. Cold peel or hot peel depending on film type.

  7. Final press for a smooth finish.

DTF printing is easier and more versatile than DTG, screen printing, or vinyl.

What Is a DTF Gang Sheet?

A DTF Gang Sheet is a large sheet or roll film filled with multiple designs. Businesses use gang sheets to save time, material, and costs by printing:

  • Multiple logos

Gang sheets maximize efficiency and reduce waste especially when produced on roll DTF printers.

Why Gang Sheets Are Essential for Print Businesses

  • Ideal for online shops selling DTF transfers

  • Perfect for batching multiple client designs

A properly arranged gang sheet improves workflow and reduces production overhead.

Top Benefits of a Gang Sheet Builder

  • Drag-and-drop simplicity

  • Instant resizing

  • Automatic spacing optimization

  • Live previews

  • Unlimited vertical length

  • Automatic tiling

  • Real-time nesting optimization

This is ideal for high-volume DTF businesses that print several meters of gang sheets daily.

UV DTF Gang Sheet Builder (For Hard Surface Stickers)

UV DTF gang sheets are the newest trend in the transfer industry. They use UV-curable ink and adhesive layers to create peel-and-stick decals for:

  • Tumblers

  • Glass

  • Mugs

  • Plastics

  • Metal
