Selecting the Right Materials:

Ink Selection: Choosing the appropriate ink is crucial for the print’s quality and durability.

Stencil Quality: A high-quality stencil ensures clear and crisp images.

Screen Mesh Count: Depending on the designโ€™s detail, mesh counts can vary. Lower counts (50-60) are suitable for thicker inks, while higher counts (110-156) capture finer details.

The Screen Printing Process:

Applying the Ink: Ink is added to the top of the screen. A squeegee is then used to press the ink through the mesh onto the substrate.

Curing the Ink: After printing, the item is heat-cured to fix the ink, enhancing the print’s durability.

Common Types of Inks Used in Screen Printing

types of inks used for screen printing apparel

Plastisol/Oil-Based Inks

Plastisol ink, a predominant industry choice, is an oil-based type of ink noted for its opacity and delicate gloss. Its placement on top of the fabric gives it a noticeable texture and solid look. The high opacity, color vibrancy, resilience, capacity for detailed printing, and economical price point make it a popular choice amongst many.

Oil-based inks offer precise color matching for true color representation, have high opacity and vivid color saturation, and allow for the printing of intricate designs.

Water-Based Inks

Ink that is water-based bears a resemblance to those utilized prior to the rise in popularity of screen printing. Water-based inks tend to have a superior and softer quality, resulting in a striking and ultra-soft end print. This ink also tends to be more environmentally friendly than other ink varieties and is usually soluble in water. Using water-based inks on darker fabrics can be slightly more challenging and may require different types of ink, but they still maintain their softness, vibrancy, and eco-friendliness.

One of the major downsides to water-based inks is its quick drying time which can make the process rather difficult for screen printers.

Best Materials to Use for Screen Printing

Recommended Fabrics for Screen Printing

Cotton and Blends: Highly absorbent and ideal for vibrant color rendering.

Silk: Requires careful handling and a higher mesh count screen for fine details.

Wool: Less absorbent, recommended for experienced printers.

Synthetic Fibers (Nylon, Polyester): Less ideal due to lower ink absorption and stretchiness.

Essential Equipment and Materials Needed for Screen Printing

Screen Printing Press: Depending on the scale of the operation, screen printing presses can be manual, semi-automatic, or automatic, each designed to securely hold the screen in place during the printing process.

Inks: A variety of specialist inks are available, each suited to different materials and desired effects. Choosing the right ink is crucial for both the look and durability of the printed item.

Squeegee: This tool, consisting of a rubber blade attached to a handle, is used to evenly distribute ink over the screen, ensuring a sharp and consistent print.

Washing Station: Post-printing, screens are cleaned at a washing station to remove all traces of emulsion, allowing for reuse of the screens.

The Screen Printing Process

everything you need to know about screen printing t-shirts

  1. Design Creation: Initially, a design is rendered onto a transparent acetate film, which is then used to transfer the design onto the screen.
  2. Screen Preparation: Apply masking tape to strategic areas of the screen to prevent emulsion from leaking. The screen is then coated with a light-sensitive emulsion.
  3. Exposing the Screen: The screen is exposed to light, hardening the emulsion except where the design blocks the light, creating the stencil.
  4. Washing and Drying: Unhardened emulsion is washed away, and the screen is dried, setting the stencil.
  5. Printing: The screen is placed over the substrate, ink is applied, and with a squeegee, the ink is pressed through the stencil onto the substrate.
  6. Curing and Finishing: After printing, the ink is cured to set it permanently onto the substrate. This may involve heat setting or UV curing, depending on the type of ink used.

Tips for Increasing the Life of Screen Printed Products

These tips will prove you with our recommendations on the best way to wash your screen printed apparel to increase its longevity and durability.

Hand Washing: For items like tote bags with rough textures, it’s recommended to use lower mesh counts. When hand washing, turn the items inside-out, use cold water mixed with mild detergent, soak for at least 10 minutes, gently agitate, then rinse and air dry.

Machine Washing and Drying: Always turn screen printed shirts inside out. Pre-treat stains and use a mild detergent on a gentle cycle with cold water. Air drying is preferable to maintain the integrity of the print, but if using a dryer, opt for the lowest heat setting.

Ironing and Steaming: Iron shirts inside-out on a low heat setting, placing a towel between the iron and the shirt. When steaming, avoid direct contact with the print and use a low temperature.

Frequently Asked Screen Printing Questions

Q: What materials are unsuitable for screen printing?ย A: Screen printing may not be effective on certain synthetic fibers such as nylon, acrylics, and polyester. These materials are less porous than natural fibers, making it difficult for screen printing ink to adhere properly, unlike how it does with cotton.

Q: How does screen printing stand out from other printing methods?ย A: Screen printing is distinctive because it allows for the creation of vibrant colors that stand out, even on darker fabrics. Additionally, the ink or paint forms layers on the surface of the fabric or paper, creating a texture that can be felt, adding a unique tactile element to the print.

Q: What strategies can enhance a screen printing business?ย A: To boost your screen printing business, you should utilize your own services to promote your work. Being customer-friendly, networking, showcasing your prints, engaging with audiences on social media, offering unique services, staying involved with your community, and providing special deals can all contribute to business growth.

Q: How often can a screen be reused in screen printing?ย A: A screen can be reused thousands of times for printing if it is properly cleaned and reclaimed. However, treating screens too harshly can reduce their lifespan, and failing to clean them thoroughly can lead to issues with emulsion adhesion, pinholes, and blurred prints.
