Step-by-Step Process of All Over Sublimation Printing Explained

 In today’s competitive custom apparel market, vibrant designs and full-coverage prints are more popular than ever. Businesses, sports teams, and fashion brands are increasingly choosing all over sublimation printing because it allows designs to cover the entire garment without limits. Unlike traditional methods, this printing technique produces seamless, high-resolution graphics that don’t crack, peel, or fade easily. If you’re curious about how it works, this guide explains the complete step-by-step process in simple terms.

What Is All Over Sublimation Printing?

All over sublimation printing is a digital printing process where heat is used to transfer dye directly into fabric. Instead of sitting on top of the material like ink in traditional printing, sublimation ink becomes part of the fabric itself. This results in vibrant, long-lasting prints that feel smooth to the touch.

This method works best on polyester fabrics or polyester-coated materials because the dye bonds permanently with synthetic fibers.

Step 1: Creating the Design

The first step in the process is creating a high-resolution digital design. Designers use graphic software like Adobe Illustrator or Photoshop to prepare artwork that fits the garment pattern.

Because the print will cover the entire garment, designers must carefully plan placement. Every inch of the fabric—front, back, sleeves, and even seams—can be printed. This makes the design phase extremely important.

Key considerations during this step:

• High-resolution images (300 DPI recommended)

• Proper color profiles for vibrant output

• Alignment with garment cut patterns

• Bleed area to avoid white gaps after stitching

A well-prepared design ensures a flawless final result.

Step 2: Printing the Design onto Transfer Paper

Once the design is finalized, it is printed onto special sublimation transfer paper using sublimation inks.

These inks are unique because they turn into gas when heated. At this stage, the design looks slightly dull on paper, which is completely normal. The vibrant colors appear after the heat transfer process.

Large-format printers are typically used for full-coverage prints to accommodate bigger fabric panels.

Step 3: Preparing the Fabric

Sublimation works best on light-colored polyester fabrics. Before printing, the fabric is:

• Cut into panels based on garment patterns

• Checked for moisture or dust

• Pre-treated if necessary

Unlike Custom Screen Printing, which can work on cotton and various materials, sublimation requires synthetic fibers to ensure proper bonding. This is one of the major differences between the two methods.

Step 4: Heat Press Transfer Process

This is the most critical step in the process.

The printed transfer paper is placed onto the fabric panel. Then both are inserted into a heat press machine. The machine applies:

• High temperature (around 380–400°F)

• Even pressure

• Controlled timing (usually 30–60 seconds)

Under heat, the sublimation ink transforms into gas and penetrates the polyester fibers. As it cools, the dye solidifies inside the fabric.

Because the ink becomes part of the material, the result is:

• No cracking

• No peeling

• No heavy texture

• Long-lasting color vibrancy

This is why sublimation is preferred for sportswear and activewear.

Step 5: Cutting and Stitching the Garment

After the fabric panels are printed, they are cut precisely according to the garment pattern (if not already pre-cut). Then, the panels are stitched together to create the final product.

Since the design was printed before stitching, the print seamlessly covers the entire garment—even across seams and edges. This is what gives the “all-over” effect.

Careful stitching ensures:

• Proper alignment of patterns

• Professional finishing

• Consistent sizing

Step 6: Quality Check

Every garment undergoes a quality inspection to ensure:

• Color consistency

• Proper stitching

• No fading or misalignment

• Smooth finishing

Because sublimation integrates dye into fabric, errors cannot be corrected easily. That’s why quality control is extremely important.

Step 7: Packaging and Delivery

Once approved, the garments are folded, packaged, and prepared for shipping.

Many businesses use this method not only for clothing but also for Personalized Promotional Products such as:

• Branded jerseys

• Event t-shirts

• Corporate uniforms

• Promotional merchandise

The ability to print edge-to-edge designs makes sublimation ideal for marketing and branding purposes.

Why Businesses Choose Sublimation Over Other Methods

There are several printing techniques available in the market, including embroidery and Custom Screen Printing. However, sublimation offers distinct advantages:

1. Unlimited Color Options

There are no additional costs per color, unlike screen printing.

2. Lightweight Feel

The print becomes part of the fabric, so there’s no heavy ink layer.

3. Durability

The design does not crack, peel, or wash off.

4. Full-Coverage Printing

Traditional printing methods cannot easily achieve complete garment coverage.

5. Cost-Effective for Small Runs

Sublimation works well for both small and bulk orders.

Common Mistakes to Avoid

While sublimation is highly effective, mistakes can affect quality:

• Using cotton instead of polyester

• Low-resolution artwork

• Incorrect heat press temperature

• Poor alignment during transfer

Working with experienced professionals helps avoid these issues.

Is All Over Sublimation Printing Right for You?

If your brand requires vibrant, high-detail graphics with long-lasting performance, sublimation is an excellent choice. It is especially popular in:

• Sportswear

• Streetwear

• Fitness apparel

• Corporate merchandise

• Fashion brands

For businesses that prioritize bold branding and durability, this method delivers exceptional results.

Final Thoughts

Understanding the complete process helps businesses make informed decisions about custom apparel production. From design preparation to heat transfer and stitching, every step plays a crucial role in delivering high-quality garments.

Whether you are launching a clothing brand, producing team uniforms, or creating branded merchandise, all over sublimation printing provides unmatched vibrancy and durability. With proper design planning and professional execution, all over sublimation printing can transform simple garments into eye-catching, premium-quality apparel that stands out in today’s competitive market.
