How to Screen Print on Long Sleeve T-shirt: A Step-by-Step Guide

Screen printing on long sleeves can be a bit tricky, but with the right tools and technique, you can achieve professional-quality results. In this tutorial, we’ll walk you through the process, covering everything you need to know—from selecting the proper equipment to aligning your design perfectly. Whether you’re a beginner or a seasoned screen printer, these tips will help you master the art of sleeve printing.

Getting Started: What You’ll Need

Before diving into the process, it’s essential to gather the necessary tools and equipment. Here’s a list of what you’ll need to get started:

1. Sleeve Palette: A tapered sleeve palette makes it easier to load the shirt and ensures that the fabric stays in place during printing.
2. Screen Size: For long sleeves, you’ll need a larger screen size than the standard. A 23×31-inch frame is ideal, as it provides enough coverage for the entire sleeve.
3. Shirt Alignment: Make sure your shirt is loaded correctly, with the collar at the top and sleeves extending down the palette. Align the seam of the sleeve with the center line on the palette for precise printing.

Setting Up the Sleeve Palette

The sleeve palette is crucial for a successful print. A tapered design helps you easily slip the shirt onto the palette, and it’s essential to ensure that the shirt stays in place. Here’s how to set it up:

1. Load the Shirt: Start by loading the shirt from the collar, pulling it down over the sleeve palette. Ensure that the sleeve seam aligns with the center line on your palette.
2. Check the Creases: Shirts often have creases that run down the center. Use these as a guide to line up the sleeve. However, if there are multiple creases, rely on the seam to ensure everything is aligned correctly.
3. Smooth It Out: Once the shirt is on the palette, smooth out any wrinkles or creases. This step is essential for a clean, even print.

Choosing the Right Screen and Mesh

For sleeve printing, a larger screen size is necessary to cover the entire sleeve length. Here’s what to consider:

• Screen Size: A 23×31-inch frame is recommended for printing on long sleeves. A standard 20×24-inch frame won’t provide enough coverage, and you’ll end up with an incomplete print.
• Mesh Count: For a simple design on a colored shirt, use a 156 mesh screen. This mesh size is versatile and works well with different ink types and fabrics.

Printing the Design

Once your setup is complete, it’s time to start printing. Follow these steps for a flawless print:

1. Load the Ink: Load your ink onto the screen and spread it evenly. For this tutorial, we’re using white ink on a gold shirt.
2. Align the Design: Make sure your artwork is centered on the screen and aligned with the centerline of the palette. This ensures that your print is perfectly positioned on the sleeve.
3. Pull the Squeegee: Pull the squeegee firmly across the screen to apply the ink. Since this is a simple print, one pass with a 156 mesh screen should be sufficient. Check to make sure the mesh is clear and the ink has transferred evenly.
4. Remove the Shirt: Carefully pull the shirt off the palette from both sides. Make sure not to let the print touch itself to avoid smudging. Hold the shirt at an angle, and guide it onto the conveyor belt for curing.

Drying and Curing

Proper drying and curing are essential to ensure the longevity of the print. Follow these steps to complete the process:

1. Lay the Shirt Flat: After removing it from the palette, lay the shirt flat on the conveyor belt. Make sure the sleeve is straight and the print is not folded over itself.
2. Adjust the Heating Element: If your conveyor dryer has an adjustable heating element, make sure it’s at the correct height for even curing. This will prevent scorching or under-curing.
3. Cure the Ink: Allow the shirt to pass through the dryer, ensuring the ink reaches the appropriate temperature for curing. For most plastisol inks, this is around 320°F.

Tips and Tricks for Perfect Sleeve Prints

1. Keep the Shirt Tight: Always make sure the shirt is tightly fitted on the palette to avoid shifting during printing.
2. Use Guide Marks: If you’re printing multiple shirts, use tape or chalk to mark the position on the palette for consistency.
3. Check the Print Before Curing: Always double-check the print before curing. If there are any imperfections, you can still make adjustments before the ink is set.

Conclusion

Screen printing on long sleeves may seem challenging, but with the right tools and techniques, it becomes a straightforward process. By following this guide, you’ll be able to create high-quality sleeve prints that stand out. Practice makes perfect, so keep experimenting with different designs and techniques to hone your skills.
