Direct To Garment (DTG) Printing: A Comprehensive Guide

Direct to Garment (DTG) printing is a modern method of printing custom designs directly onto fabric using specialized inkjet technology. This technique has revolutionized the custom apparel industry by allowing for high-quality, detailed prints with a wide color range. As we provide custom dtg printing on shirts in Dallas so in this article we will explore what DTG printing is, its advantages, the equipment required, and a step-by-step guide on how to perform DTG printing on custom shirts.

What is Direct to Garment (DTG) Printing?

DTG printing involves using a specialized printer to apply water-based inks directly onto fabric, similar to how an inkjet printer works on paper. The inks are absorbed by the fibers of the fabric, resulting in a durable and vibrant print. This method is particularly effective for detailed and colorful designs, making it ideal for custom shirts.

Advantages of DTG Printing

High-Quality PrintsWide Color Range
Detailed Designs
Quick Turnaround
No Minimum Order Quantity
Environmentally Friendly
High-Quality Prints
DTG printing produces high-resolution prints with smooth gradients and sharp details. The water-based inks penetrate the fabric, creating a soft, breathable print that feels part of the shirt rather than sitting on top of it.

Wide Color Range

DTG printers can produce millions of colors, making it possible to print complex designs with multiple hues and gradients. This capability is a significant advantage over traditional screen printing, which is limited by the number of screens and colors that can be used.

Detailed Designs

Because DTG printers work similarly to inkjet printers, they can replicate intricate details and fine lines that would be challenging to achieve with other printing methods. This makes DTG ideal for custom artwork, photographs, and other detailed designs.

Quick Turnaround

DTG printing has a relatively fast setup time compared to screen printing, which requires creating screens for each color in the design. This speed allows for quicker turnaround times, making DTG printing suitable for small orders and last-minute jobs.

No Minimum Order Quantity

DTG printing does not require the setup of screens or plates, making it cost-effective for small orders and one-off designs. This flexibility is ideal for individuals, small businesses, and events that need custom shirts in limited quantities.

Environmentally Friendly

DTG printing uses water-based inks that are typically eco-friendly and less harmful to the environment compared to the plastisol inks used in screen printing. Additionally, the ability to print on demand reduces waste, as there is no need for large inventory storage.

The core piece of equipment for DTG printing is the DTG printer itself. There are various models available, ranging from entry-level printers suitable for small businesses to industrial-grade machines for high-volume production. Some popular brands include Epson, Brother, and Kornit.

Pre-Treatment Machine

For dark-colored shirts, a pre-treatment solution is necessary to ensure the ink adheres properly to the fabric. A pre-treatment machine sprays this solution evenly onto the shirt before printing. While it is possible to apply pre-treatment manually, a machine provides consistent results.

Heat Press

A heat press is used to cure the ink after printing, ensuring it bonds properly with the fabric. The heat press also helps set the pre-treatment solution before printing. It’s essential to have a reliable heat press with adjustable temperature and pressure settings.

Design Software

Design software such as Adobe Photoshop, Illustrator, or CorelDRAW is crucial for creating and preparing artwork for printing. Many DTG printers come with their own software or plugins that integrate with popular design programs to manage color profiles and print settings.

Quality Blank Shirts

The quality of the blank shirts used for DTG printing significantly affects the final product. Shirts made of 100% cotton or high-cotton blends are ideal because they absorb the ink better and produce more vibrant prints.

How to Perform DTG Printing on Custom Shirts: A Step-by-Step Guide

Step 1: Design Preparation

Create or Choose a Design: Use design software to create a new design or modify an existing one. Ensure the design is high resolution (at least 300 DPI) for the best print quality.
Color Management: Adjust the colors in your design to match the color profile of your DTG printer. This step ensures that the printed colors closely match the digital design.

Step 2: Pre-Treat the Shirt

Prepare the Shirt: Make sure there are no creases or dirt on the clothing. Lay it flat on a surface.
Apply Pre-Treatment Solution: Use a pre-treatment machine or spray bottle to apply the pre-treatment solution evenly across the area where the design will be printed.
Dry the Pre-Treatment: Use a heat press to dry the pre-treatment solution. Set the heat press to the recommended temperature (usually around 330°F or 165°C) and press for 30-45 seconds.

Step 3: Print the Design

Load the Shirt onto the Printer: Carefully load the pre-treated shirt onto the platen of the DTG printer. Ensure it is flat and properly aligned.
Print the Design: Send the design from your computer to the DTG printer. Adjust the print settings according to the fabric type and color. Start the printing process, ensuring the printer head is set to the correct height to avoid smudging.

Step 4: Cure the Ink

Prepare the Heat Press: Set the heat press to the appropriate temperature (usually around 340°F or 170°C) and pressure settings.
Cure the Print: Place the printed shirt on the heat press. Cover the design with a Teflon sheet or parchment paper to protect it. Press the shirt for 90-120 seconds to cure the ink and ensure it bonds with the fabric.

Step 5: Quality Control and Finishing

Inspect the Print: Check the printed shirt for any imperfections, such as smudges or misalignment.  
Final Touches: Remove any loose threads or lint from the shirt. Fold and package the shirt neatly for delivery or display.
Tips for Successful DTG Printing
Use High-Quality Artwork: Ensure your designs are high resolution to achieve the best print quality.
Regular Maintenance: Perform regular maintenance on your DTG printer, including cleaning the print heads and replacing worn parts, to ensure consistent performance.
Experiment with Settings: Adjust print settings such as ink density and print speed to find the optimal configuration for different fabrics and designs.
Stay Updated: Keep up with the latest advancements in DTG technology and best practices to improve your printing process continually.
