How Screen Printing Works: Process, Costs & Why It’s Worth It

Screen printing is a classic method used to print designs on apparel and promotional products like bandanas, shirts, and more. It’s one of the most popular and effective ways to create custom, high-quality items. But it’s also a process that requires skill, time, and materials, which is why it might be priced differently compared to newer techniques like Direct-to-Film (DTF). Let’s break down how it works and why it’s often the best option for larger orders.

The Screen Printing Process: Step-by-Step

Design Preparation

The first step in screen printing is preparing your design. This involves vector artwork that is converted into a “stencil” or screen, called “separations.” This is a learned skill that not everyone can perform. Each color in your design requires a separate screen, so multi-color designs need more time and effort to separate before the screen making process.

Printing the Films

Once the design is ready, it’s printed onto transparent films using a high tech, expensive, printer. Each color of the design gets its own film. This step is crucial because these films will be used to create the screens. The films act as a blueprint for transferring the design onto the mesh of the screen.

Screen Creation

The next step is to create the screens, which involves coating them with a light-sensitive emulsion and exposing them to UV light. The areas of the screen that aren’t exposed to light harden, and the areas that are exposed wash away. This creates the stencil that will hold each part of the design.

Setting Up the Automatic Press

Before applying ink, the screens are set up on the automatic press (or manual). Each screen is carefully aligned with the printing station to ensure that the design registers correctly on the garment. This step requires precision to guarantee that the colors line up perfectly and the print is crisp.

Ink Color Mixing (Pantone Matching)

Before printing, it’s time to mix the right colors. For designs requiring precise colors, Pantone matching is used to ensure that the ink matches exactly what the client requested. Pantone colors are standardized shades that ensure consistency. The ink is carefully mixed to achieve these exact colors, which is a critical step in maintaining the design’s integrity.

Printing

The screens are then placed on the items you want to print, and ink is pushed through the mesh with a squeegee. For each color in the design, a separate screen is used to apply ink. A layered, or puzzle, effect. This process gives screen printing its iconic, vibrant finish.

Drying and Curing

After printing, the items are pulled from the press, put on a large conveyor, dried and cured in a dryer to ensure the ink sets and stays intact through washing. This is why screen printing lasts longer compared to some other methods.

Why Set Up Fees Are Charged

Screen printing involves several steps to get a design onto the item. The setup, including preparing the screens, mixing inks, and getting the machine ready, takes time and resources. The more screens required for a design (for multiple colors), the higher the setup costs.

Screen Printing vs. DTF: Why It Might Be More Expensive

Direct-to-Film (DTF) printing is a newer method that involves printing directly onto a transfer film and then applying it to the item. While DTF may be a cheaper option for small runs, and uses less set up time, screen printing may provide a longer-lasting result.

The Cost of Small Orders

While screen printing is fantastic for large orders, it doesn’t scale well for small quantities. The setup costs (creating screens, mixing inks, etc.) remain constant, even if you’re only ordering a few items. So, the price per item goes up significantly for smaller orders. If you only need a handful of shirts or bandanas, a smaller order might not be worth the investment when compared to other methods like DTF.

Why Screen Printing Is Still the Best Option

Despite its higher upfront cost, the screen printing process is highly customizable. For businesses or events that need a high volume of printed products, screen printing is often the most cost-effective choice in the long run. Plus, it’s in high demand because of the superior finish it offers.

In Conclusion

Screen printing is an art that offers unmatched durability, quality, and vibrancy, making it ideal for larger orders. While the setup costs and time may make small orders more expensive, we can always pivot to DTF for your smaller runs.
