DTF Printing vs. Screen Printing

DTF Printing vs. Screen Printing : Profitability 

What is Direct to Film (DTF) printing?

DTF printing, or Direct-to-Film printing, uses a special printer for making cool designs on a clear film. These designs can be stuck onto many different things, even tricky materials like polyester. The process starts by printing the design on the film, adding a special powder, and then using heat to transfer it onto the final item with a press.

What is Screen Printing?

Screen printing is a way of putting ink or dye onto things using a special mesh. A stencil blocks some parts, so ink only goes where it should. A tool called a blade or squeegee spreads ink on the mesh, and when it moves away, the mesh touches the thing to be printed for a little bit. This makes the ink stick and creates a design. Each colour needs its turn, so different screens are used for colourful pictures or designs.

Production Process for DTF
The DTF (Direct-to-Film) production process is a method used to print designs on various surfaces, including fabrics and other materials. Here's a simplified explanation of the DTF production process:

• Design Creation:
• Begin by creating the design you want to print on a computer.
• Printing on Film:
• Use a special printer to print the design onto a clear film. This film acts as a transfer medium for the design.
• Thermo-Adhesive Powder Application:
• Apply a special thermo-adhesive powder over the printed design on the film. This powder helps the design stick to the final surface.
• Heat Transfer:
• Place the film with the design and thermo-adhesive powder on the substrate (the item you want to print on).
• Use a heat press to transfer the design from the film onto the substrate.
• The heat causes the thermo-adhesive powder to stick the design to the substrate.
• Cooling and Final Result:
• Allow the substrate to cool down.
• Once cooled, the design is now permanently attached to the substrate.

This process allows for detailed and colourful designs to be transferred onto various materials, offering a versatile and efficient way of customizing items. It's commonly used in garment printing and can be applied to materials that may be challenging for other printing methods, such as polyester.

Production Process for Screen Printing

Screen printing is a versatile printing technique that involves transferring ink onto a substrate (like fabric or paper) through a mesh screen. Here's a simplified explanation of the screen printing production process:

• Design Creation:
• Start by creating the design you want to print. This could be a logo, artwork, or any image.
• Screen Preparation:
• Create a mesh screen for each colour in the design.
• Apply a blocking stencil on the screen, leaving open areas corresponding to the design elements.
• Ink Application:
• Place the screen over the substrate.
• Use a blade or squeegee to spread ink over the open mesh areas of the screen.
• The ink passes through the mesh and transfers onto the substrate only where the stencil allows.
• Print Stroke:
• Move the blade or squeegee across the screen, forcing the ink through the mesh onto the substrate.
• This action ensures the ink adheres to the substrate in the desired pattern.
• Reverse Stroke:
• Lift the screen away from the substrate.
• A reverse stroke or spring action of the screen helps detach it from the substrate, preventing smudging.
• Color Layering (if needed):
• Repeat the process for each color in the design, using a separate screen for each color.
• Layer the colors on top of each other to create a multi-colored design.
• Drying:
• Allow the printed substrate to dry thoroughly between each colour application.
• Curing (Optional):
• In some cases, the printed substrate may undergo a curing process, often involving heat, to ensure the ink sets permanently.

The screen printing process is particularly effective for producing vibrant and durable prints on various materials. It's widely used in apparel, posters, and promotional item production due to its ability to handle both simple and intricate designs.

Cost Analysis for 500 Shirts, 6 Colours:

Screen Printing:

• Screen Setup (6 colours): $50/colour * 6 colours = $300
• T-Shirts: 500 black t-shirts at $4 each = $2000
• Print Cost: 500 shirts * $4.30/print = $2150
• Labour Cost: (500 shirts / 100 shirts per hour) + 1 hour setup = 6 hours
• 6 hours * $20/hour (hypothetical labour cost) = $120
• Total Cost: $300 (Screen) + $2000 (T-Shirts) + $2150 (Print) + $120 (Labour) = $4570

DTF Printing:

• T-Shirts: 500 black t-shirts at $4 each = $2000
• Print Cost: $3/print * 500 prints = $1500
• Labour Cost: (500 shirts / 150 shirts per hour) = 3.33 hours
• 3.33 hours * $20/hour (hypothetical labour cost) = $66.67
• Total Cost: $2000 (T-Shirts) + $1500 (Print) + $66.67 (Labour) = $3566.67

Analysis:

• For 500 shirts with 6 colours, adjusted screen printing cost with labour is $4570.
• DTF printing, under the same conditions, has a total cost of $3566.67.
• Even with labour costs considered, DTF printing remains a more cost-effective option, with a difference of $1003.33 compared to screen printing for this scenario.

Additional Note:

• Labour costs significantly impact the overall expenses, and DTF printing's higher production rate per hour contributes to its cost-effectiveness, particularly for larger quantities.

Screen Printing:

Durability Factors:

• Ink Quality: The durability of screen prints heavily relies on the quality of the ink used. High-quality, properly cured inks contribute to longer-lasting prints.
• Curing Process: Proper curing during the screen printing process is crucial for ink adhesion and durability. Inadequate curing can result in premature fading or cracking.

Considerations:

• Screen printing is well-established, and with proper materials, processes, and experienced printers, it can provide durable prints for a considerable number of wash cycles.
• The type of fabric used for the substrate can also impact the longevity of screen prints.

DTF Printing:

Durability Factors:

• Consumable Quality: The quality of the DTF film, thermo-adhesive powder, and ink used can significantly impact the durability of the print.
• Curing Process: Like screen printing, proper curing in the DTF printing process is essential for achieving a durable print.

Considerations:

• DTF printing has shown promising durability, especially with advancements in consumable materials. However, the technology is relatively newer, and the long-term performance may be influenced by ongoing developments.
• DTF printing can be suitable for a variety of fabrics, including those that may stretch or bend.

Summary:

• Screen Printing Durability: With the right materials and processes, screen printing can offer durable prints for 40-50 washes or more. It's a well-established method known for its resilience when executed properly.
• DTF Printing Durability: DTF printing has demonstrated good durability with prints lasting 50-100 washes. The quality of consumables and adherence to proper curing methods are crucial factors.

Choosing Between Screen Printing and DTF Printing for Durability:

• Screen Printing: A reliable choice for industries where long-lasting prints are essential, especially for workwear and sportswear.
• DTF Printing: Suitable for applications where a balance between durability and vibrant, detailed designs is desired. Ongoing advancements in DTF technology may further enhance durability.

Ultimately, the choice between screen printing and DTF printing should consider the specific requirements of the project, the intended use of the printed items, and the available technology and expertise. Both methods can provide durable prints when executed with care and using high-quality materials.
