Whether you run a garment printing business or you’re just getting started, this SEO-friendly, website-ready article will help you improve print quality and reduce costly mistakes.

Introduction to DTG Printing

Direct to Garment (DTG) printing is one of the most advanced textile printing technologies available today. It allows you to print high-resolution, full-color images directly onto cotton and cotton-blend fabrics using specialized water-based inks.

DTG printing is widely used for:

• Custom T-shirts

• Fashion brands

• Print-on-demand businesses

• Small-batch apparel production

• Promotional merchandise

The biggest advantage of DTG printers is their ability to capture fine details, gradients, and photorealistic designs. However, like any digital printing system, DTG printers require proper maintenance and correct process control.

Two major quality issues that printers often face are:

• Banding (lines appearing in prints)

• Fading (loss of color vibrancy over time)

Let’s understand these problems in depth.

What Is Banding in DTG Printing?

Banding refers to unwanted horizontal lines or streaks that appear across your printed design. These lines disrupt the smooth appearance of the image and reduce overall print quality.

How Banding Looks

• Thin white horizontal lines

• Uneven ink distribution

• Striped or streaked appearance

• Inconsistent color density

Banding is especially noticeable in solid color areas or large background prints.

What Causes Banding in DTG Prints?

Several technical factors can cause banding. Understanding the root cause is the first step to solving the problem.

1. Clogged Print Head Nozzles

The most common cause of banding is clogged nozzles in the print head. DTG inks contain pigments that can settle or dry if the printer is not used regularly.

When certain nozzles are blocked:

• Ink is not sprayed evenly

• Missing lines appear in the design

• Print quality becomes inconsistent

2. Misaligned Print Heads

If the print head alignment is off, ink droplets may not land correctly on the fabric. This results in visible horizontal lines or slight overlaps that look like banding.

3. Low Ink Levels

Running ink cartridges close to empty can introduce air into the system, leading to uneven ink flow and visible lines.

4. Incorrect Print Settings

Improper resolution settings, pass count, or platen height adjustments can also create banding.

5. Poor Fabric Surface

Uneven fabric texture or lint buildup can interfere with smooth ink deposition.

How to Fix Banding in DTG Printing

Now let’s discuss practical solutions to eliminate banding and restore print quality.

Perform a Nozzle Check

Most DTG printers come with a built-in nozzle check feature. Run a nozzle test pattern to identify which nozzles are clogged.

If gaps appear in the test print:

• Perform a print head cleaning cycle

• Repeat the nozzle check

• Avoid excessive cleaning to prevent ink waste

Regular nozzle checks are essential for consistent DTG printing performance.

Clean the Print Heads Properly

If standard cleaning does not fix the issue:

• Use manufacturer-recommended cleaning solutions

• Perform a manual cleaning (if required)

• Ensure the capping station is clean

Never use harsh chemicals, as they can permanently damage the print head.

Align the Print Heads

Print head alignment ensures that ink droplets land precisely on the garment.

Steps typically include:

1. Access alignment settings in printer utility software

2. Print alignment pattern

3. Adjust settings based on instructions

4. Reprint test image

After alignment, print a sample design to confirm the issue is resolved.

Check Platen Height

If the garment is too far from or too close to the print head, ink may not distribute evenly.

Make sure:

• Fabric lies flat

• No wrinkles are present

• Platen height matches garment thickness

Maintain a Clean Printing Environment

Dust, lint, and fabric fibers can affect print performance.

Best practices include:

• Lint-rolling garments before printing

• Keeping workspace clean

• Storing inks properly

• Printing regularly to prevent ink drying

What Is Fading in DTG Printing?

Fading occurs when printed colors appear dull, washed out, or lose vibrancy after washing. Unlike banding, fading may not be visible immediately after printing but becomes noticeable over time.

Common Causes of Fading in DTG Prints

1. Incorrect Pre-Treatment Application

Pre-treatment is essential for dark garments and sometimes even light fabrics. It helps white ink bond to the fibers and enhances color vibrancy.

If pre-treatment is:

• Applied unevenly

• Too little

• Too much

The result can be dull or faded prints.

2. Improper Curing Process

Curing locks the ink into the fabric. Without proper heat and time:

• Ink sits on the surface

• Wash durability decreases

• Colors fade quickly

Heat presses or conveyor dryers are commonly used for curing.

3. Incorrect Temperature Settings

If curing temperature is too low:

• Ink doesn’t bond properly

If temperature is too high:

• Ink may scorch

• Fabric may burn

• Colors may shift

4. Poor Quality Garments

Not all fabrics are suitable for DTG printing. Low-quality cotton blends may not absorb ink effectively.

For best results:

• Use 100% ring-spun cotton

• Choose tightly woven garments

• Avoid heavily treated fabrics

5. Overwashing or Harsh Detergents

Even perfectly printed garments can fade if customers:

• Wash in hot water

• Use strong detergents

• Dry at high heat

Providing proper wash care instructions can significantly improve print longevity.

How to Fix and Prevent Fading in DTG Prints

Optimize the Pre-Treatment Process

To achieve consistent results:

• Use a high-quality pre-treatment solution

• Apply evenly using a spray machine or automatic pre-treater

• Avoid pooling or oversaturation

• Heat press pre-treatment before printing

Proper pre-treatment dramatically improves color brightness and wash durability.

Follow Correct Curing Guidelines

Always follow the manufacturer’s curing instructions.

Typical curing parameters:

• Temperature: 160–170°C (may vary by ink brand)

• Time: 60–180 seconds

• Even pressure distribution

Use a temperature gun to verify actual heat press temperature.

Test Before Bulk Production

Before printing large orders:

• Print a test sample

• Cure properly

• Wash test the garment

• Evaluate color retention

This small step prevents large financial losses.

Use High-Quality DTG Inks

Cheap or incompatible inks can compromise durability.

Always:

• Use recommended inks

• Store inks at proper temperatures

• Shake white ink daily to prevent settling

Provide Wash Care Instructions to Customers

Educate customers to:

• Wash inside out

• Use cold water

• Avoid bleach

• Air dry or tumble dry low

This ensures long-lasting DTG prints.
