Most Common Type of T-Shirt Printing

To help you understand the options available, we've listed the major and most frequently used T-shirt printing techniques. While only traditional methods were available in the past, the rise of custom printing has made bulk T-shirt printing immensely popular. By understanding the pros and cons of each technique, you'll be equipped to choose the method that best suits your needs.

Direct-To-Garment Printing (DTG)

Direct-to-garment (DTG) printing operates much like an inkjet printer for paper. This method uses a specialized printer to apply water-based ink directly onto the fabric. It excels at reproducing intricate designs, full-color graphics, and highly detailed artwork. DTG is particularly ideal for small batch orders due to its minimal setup requirements.

How It Works: A digital design file is sent directly to the DTG printer. The garment is first pre-treated (if necessary) and precisely positioned. The printer then sprays the ink onto the fabric. Finally, the garment passes through a heater to cure the ink, ensuring the design permanently adheres.

Pros

l   Excellent for Detailed Designs: DTG excels at printing highly complex designs with multi-colors, gradients, and photographic detail.

l   Soft Hand Feel: The water-based ink penetrates the fabric fibers, creating a seamless integration with the material and resulting in a very soft texture.

l   Durable & Eco-Friendly: The prints are wash-resistant and can withstand more than 60 washes without significant cracking or fading. The water-based inks are also more environmentally friendly.

Cons

l   High Cost for Bulk Orders: DTG can be more expensive per unit for large orders compared to screen printing.

l   Fabric Limitations: This method works best on 100% cotton. Printing on polyester or dark-colored garments often requires pre-treatment, which can add steps and cost.

l   Longer Production Time: The process of pre-treating, printing, and curing each garment individually makes it less efficient for high-volume projects than other methods.

Screen Printing

This is one of the most popular and effective methods of garment printing, often referred to as silk screen printing. This precise and well-established technique uses a stencil to apply ink onto the fabric. It is ideal for producing vibrant and durable designs on textiles.

However, while many believe it is best suited for simple designs with limited colors, the truth is that colorful and intricate designs can be achieved with technical knowledge and experience in artwork separation and halftones.

How It Works: the first step involves creating a mesh screen, typically made from nylon or synthetic materials. A digital design is printed onto a transparent acetate film, which acts as a stencil. The screen is then placed over the garment, and ink is squeezed across it, transferring the design onto the fabric. For multicolor prints, multiple screens are used, each applying a different color.

Pros

l   The ink used in screen printing bonds well with the fabric, resulting in a highly durable and long-lasting print.

l   Screen printing is a cost-effective method for large production runs.

l   Screen printing is suitable for application on a wide variety of materials and garments.

Cons

l   Wet ink can be prone to smudging immediately after printing, requiring careful handling.

l   The process typically uses more ink and generates more material waste than DTG (Direct-to-Garment) printing, making it less environmentally friendly.

l   It is less cost-effective and therefore less profitable for small-scale or custom one-off projects.

Dye Sublimation Printing

Dye sublimation, often referred to as all-over printing, allows for the application of designs across the entire garment, including the seams. This technique produces stunning, full-color, or repeating patterns that become a permanent part of the fabric. It works best on synthetic materials like polyester, which yield excellent color vibrancy and sharpness.

How It Works: first, the design is created as a digital file and printed onto special sublimation paper using heat-activated inks. The paper is then placed on the garment and pressed under high heat. This process causes the ink to turn into a gas, permeate the fabric fibers, and bond with them as it cools, resulting in a permanent transfer of the design.

Pros

l   It produces extremely durable, high-quality prints that are resistant to fading and cracking.

l   Sublimation prints have a soft, breathable feel, as the dye bonds with the fabric fibers instead of sitting on top.

l   It delivers excellent results on synthetic fabrics like polyester, as the dye fully penetrates the material during the heating process.

Cons

l   This method is not suitable for 100% cotton or dark-colored garments; it works best on white or light-colored synthetic fabrics.

l   It is generally more expensive than other common t-shirt printing techniques, such as screen printing.

Heat Transfer Printing

Heat transfer printing differs from other methods as it does not directly apply dye or ink onto the fabric. Instead, it uses pre-printed designs on transfer paper, making it a versatile technique suitable for both small businesses and large-scale production.

This popular method allows almost any design or image to be printed onto a garment, making it an excellent choice for adding a personalized touch to apparel.

How It Works: a design is first printed or cut onto a special transfer paper or vinyl using a digital printer or vinyl cutter. The paper is then placed onto the fabric and pressed with a heat press. Through the combination of heat and pressure, the design is permanently adhered to the material.

Pros

l   This method is highly versatile, allowing for printing on a wide range of fabrics and items such as t-shirts, hats, and tote bags.

l   Heat transfer printing is particularly cost-effective and ideal for small batches or custom orders.

l   It is considered one of the more environmentally friendly printing options due to its lower material waste and minimal use of consumables.

Cons

l   The prints are generally less durable than those achieved through traditional screen printing and may crack or fade over time.

l   Color options can be limited, making it difficult to perfectly match specific brand colors or intricate color schemes.

Airbrushing

Unlike conventional printing methods, airbrushing is a manual technique that uses a handheld airbrush tool to spray a fine mist of paint onto fabric, elevating the process to an artistic level. This method can produce highly detailed, photorealistic designs.

It is important to note that the durability of the print depends on using the correct type of spray paint and fabric. For best results, it is recommended to use fabric sprays favored by skilled professionals.

How It Works: a stencil is first created for the design outline and temporarily adhered to the t-shirt. The artist then mixes the paint and uses the airbrush tool to apply it in fine layers over the stencil. Heat is often applied at the end to cure the paint and ensure it permanently bonds to the fabric.

Pros

l   It is relatively easy to start with and offers great artistic freedom, allowing for nearly unlimited design possibilities.

l   It is an inexpensive method for applying custom designs to various types of t-shirts.

l   It is capable of creating highly detailed, photorealistic graphics and subtle visual effects.

Cons

l   It requires proper artistic skill and practice to control the airbrush and achieve high-quality results.

l   The process can be very time-consuming, especially for intricate and multicolored designs.

Discharge Printing

Discharge printing, also known as extract printing, is a unique method for decorating dark-colored fabrics. Instead of applying a new layer of pigment, it uses a chemical agent to remove (or "discharge") the original dye from specific areas of the fabric. This technique results in a soft, smooth print that becomes an integral part of the material itself.

How It Works: a stencil is applied to protect certain areas of the fabric from the discharge agent, which typically contains chemicals like hydrosulfite. The agent is then applied, which removes the dye from the exposed areas, revealing the fabric's natural lighter color or creating space for a new color to be added. Finally, the fabric is washed and dried to remove any residual chemicals, leaving a permanent, soft-to-the-touch design.

Pros

l   Discharge printing creates a remarkably soft print that becomes part of the fabric, ensuring maximum comfort.

l   It is an eco-friendly approach, as it removes or repurposes the existing dye in the fabric rather than applying a new opaque layer of ink.

l   It allows for vibrant and intricate designs to be achieved even on dark-colored garments.

Cons

l   The process requires a specific chemical agent and careful application to avoid damaging the fabric fibers.

l   This method is predominantly effective on dark-colored, reactive-dyed fabrics, such as black and navy blue.
