Screen printing is a simple way to create custom t-shirts with vibrant, long-lasting designs. Here’s a quick overview of the process:
- What You’ll Need:
- Tools: Screen printing frame, mesh screens, squeegee, and photo emulsion.
- Supplies: Ink, cleaning solutions, and film positive for your design.
- Safety: Gloves and proper ventilation.
- Steps to Get Started:
- Prepare Your Design: Use clean lines, simple fonts, and high-contrast images.
- Transfer to Film: Print your design on transparency film.
- Prep the Screen: Coat the screen with emulsion, dry it, and expose the design.
- Print: Align your garment, apply ink with a squeegee, and cure the print with heat.
- Tips for Success:
- Use a mesh count that fits your design (110-160 for beginners).
- Test your setup on scrap fabric before printing.
- Clean tools immediately after use to extend their lifespan.
Screen printing is ideal for bulk orders and works on various fabrics. Start with single-color designs to practice your technique, and soon you’ll be creating professional-quality prints!
Design Setup
Making Your Design
Focus on clean lines and clear shapes to ensure your design transfers effectively. For text, pick fonts that stay easy to read, even when resized.
| Design Component | Tips for Success |
|---|---|
| Text | Stick with clear, readable fonts. |
| Colors | Simplify with single-color designs to save on costs. |
| Artwork | Use high-contrast images with sharp edges. |
| Spacing | Leave enough room between elements to avoid crowding. |
After finalizing your design, double-check its size and format to ensure smooth printing.
Design Size and Format
The size and placement of your design are key to achieving great print quality. Make sure your artwork fits neatly within the garment’s designated printing area. Keep in mind that larger designs require more ink and screen space, which can increase costs and complexity.
Here are some important points to consider:
- Design Placement: Position your design centrally, leaving appropriate space below the collar.
- Scale Ratio: Maintain consistent proportions when resizing parts of your design.
- Print Area: Leave a margin around the edges to avoid printing too close to seams.
Once the size is perfect, convert your design into a high-opacity film to prepare for exposure.
Transfer to Film
When your design is ready and sized correctly, it’s time to transfer it onto film. Use screen printing transparency film for the best results.
Follow these steps to prepare your film positive:
- Printer Settings
Adjust your printer to its highest quality setting. Use black ink at maximum density, and check the opacity by holding the film up to light. - Film Handling
Handle the film with care to avoid smudges or fingerprints. Store the film flat in a clean, dry place to keep it in good condition.
Screen Preparation
Mesh Selection
The mesh count of your screen plays a key role in print quality and how much ink gets deposited. For most beginners, a mesh count between 110 and 160 is a good starting point for basic designs. If you’re working on detailed artwork, go for higher mesh counts (200+). On the other hand, lower mesh counts (60-110) are best for thicker ink deposits or special effects.
| Design Type | Recommended Mesh Count | Best For |
|---|---|---|
| Basic Text | 110-125 | Standard t-shirt prints |
| Fine Details | 155-230 | Small text, halftones |
| Heavy Coverage | 60-110 | Athletic numbers, block letters |
| Specialty Inks | 86-110 | Glitter, metallic effects |
Once you’ve chosen the right mesh, it’s time to coat your screen with emulsion.
Emulsion Application
This step should be done in dim lighting to avoid exposing the emulsion prematurely.
1. Preparation
Start with a clean, dry screen. Position the screen at a slight angle and pour a line of emulsion along the bottom edge.
2. Coating Process
Using a scoop coater, hold it at about a 15° angle and pull the emulsion upward in one smooth motion. For beginners, applying two coats on the print side and one coat on the squeegee side works well.
3. Drying
Lay the coated screen flat in a dark, dust-free area. Use a fan to improve air circulation, but avoid pointing it directly at the screen. Drying typically takes 2–4 hours at a temperature of 68–72°F.
Design Exposure
Once your screen is coated and dry, you’re ready to expose your design.
What You’ll Need:
- A UV exposure unit or a 500W halogen work light
- A black surface to place under the screen
- Clear glass or plexiglass to hold the film positive flat
- An exposure calculator for testing times
Steps to Expose Your Design:
- Place your film positive on the print side of the screen.
- Lay a piece of glass over the film to ensure it stays flat against the screen.
- Expose the screen for 2–5 minutes. Test a corner to check if the exposure is correct, then wash out the design with medium water pressure.
- Make sure the screen is completely dry before moving on to printing.
Common Issues and Fixes:
- Underexposed: The design washes away too easily.
- Overexposed: Fine details are difficult to clean out.
- Ideal Exposure: Sharp edges with no emulsion loss.
Printing Steps
Workspace Setup
Set up your screen printing workspace in a well-lit and ventilated area. Divide the space into three main zones for efficiency:
- A pre-print zone for prepping garments and storing blank shirts.
- A print zone with your press and all necessary supplies.
- A post-print zone for drying racks and curing equipment.
Keep the room at a stable temperature with controlled humidity to ensure smooth ink flow and proper curing.
Print Alignment
Once your workspace is ready, focus on accurate alignment. Use painter’s tape to mark center lines on your platen – these serve as dependable guides for garment placement.
Helpful Alignment Tips:
- Use a T-square to create straight, perpendicular guidelines.
- Position designs 3–4 inches below the collar for adult shirts.
- Mark film positives with registration marks that extend beyond the design edges.
- Test your setup by printing on scrap fabric before starting your production run.
For multi-color designs, double-check that the registration marks on all screens align perfectly.
Ink Application
Applying ink correctly is key to achieving sharp, consistent prints. Start by flooding the screen with a thin, even layer of ink.
Print Stroke Basics:
- Hold the squeegee at a steady angle.
- Apply firm, even pressure as you pull the squeegee toward you in one smooth motion.
Adjust the ink consistency based on the fabric and design details. For darker garments, use flash printing between layers to build up solid coverage.

Final Steps
With printing finished, it’s time to wrap things up with these important tasks.
Heat Curing
Heat curing is key to keeping your prints looking great and lasting longer:
- Set your heat press to 320°F.
- Press each printed area for 60 seconds.
- Check the cure by gently stretching the fabric – ink that’s cured properly won’t crack.
- Let shirts cool completely before stacking or packaging them.
Equipment Cleanup
Cleaning your tools right after use helps maintain quality and extends their lifespan:
- Screen Cleaning
- Scrape off excess ink with a spatula.
- Use a cleaning solution specifically designed for screens.
- Rinse thoroughly with water.
- Remove any leftover ghost images with emulsion remover.
- Tool Maintenance
- Clean squeegees with the right solvent.
- Wipe down all work surfaces.
- Dispose of cleaning materials responsibly.
- Inspect your equipment for any damage or wear.
Supply Storage
Storing your supplies the right way keeps them in good condition and easy to find:
| Supply Type | Storage Tips |
|---|---|
| Inks | Keep in air-tight containers at room temperature. |
| Screens | Store vertically in a dust-free area. |
| Chemicals | Place in a cool, dark space with proper ventilation. |
| Tools | Organize in a clean, dry area by their function. |
Wrap-Up
Quick Review
Achieving great results in screen printing comes down to mastering the process. From preparing your design and transferring it to film, to coating screens, exposing them properly, and applying ink with precision – each step matters. Don’t forget: heat curing at 320°F is crucial for long-lasting prints.
Here are some common issues and how to address them:
| Problem | Fix |
|---|---|
| Uneven ink coverage | Apply consistent, firm pressure with the squeegee |
| Blurred edges | Check screen tension and adjust off-contact distance |
| Cracking due to incomplete curing | Ensure the full heat press cycle is completed |
Keep these solutions in mind as you start your screen printing journey.
