Chapter 1
What is screen printing?
Screen printing is a printing process in which woven mesh supports a stencil that controls where ink passes onto the garment. Open areas of the stencil allow ink to pass through the mesh, while closed areas prevent ink from reaching the garment.
During printing, a squeegee moves across the screen and transfers ink through the open image area. Although the basic principle is simple, consistent production depends on controlling the relationship between the artwork, screen, stencil, ink, squeegee, press, garment and curing process.
Screen printing at a glance
Quick Fact
The screen does more than hold the artwork. Mesh selection, stencil thickness and screen condition all influence how ink transfers to the garment.
Dynamic Perspective
A good print begins long before the squeegee moves. Screen printing works as a system, and decisions made during artwork and screen preparation affect registration, ink deposit, print quality and production speed later in the process.
How the complete screen printing process works
The 9-step production process
Garment screen printing is a step-by-step process. Each step builds on the previous one, and the decisions you make early in the process affect print quality, production speed and overall results.
1. Artwork & Separations
Prepare artwork and separate colors for screen printing. Each color in the design requires its own screen.
2. Screen Preparation
Coat the screen with emulsion; allow it to dry and expose it with the artwork to create the stencil.
3. Washout & Inspection
Wash out the exposed screen to open the image area and inspect for quality, making any needed touch-ups.
4. Press Setup & Registration
Install the screens on the press, align and register each color, and set print stroke, off-contact and other settings.
5. Printing
Apply ink and print each color in sequence, maintaining consistent technique and ink deposit.
6. Flashing (As Needed)
Flash cure between colors when needed to prevent colors from mixing and to keep registration clean.
7. Final Curing
Fully cure the ink to the manufacturer’s recommended temperature, dwell time and settings.
8. Quality Control
Inspect the finished print for color accuracy, registration, coverage and cure. Make adjustments as needed.
9. Cleanup & Reclaim
Clean ink from the screens and reclaim them for future use. Proper cleanup extends screen life and maintains consistent results.
Key Takeaways
- Each step affects the next step.
- Proper setup and technique lead to consistent results.
- Good prints depend on the entire process, not just one step.
Dynamic Perspective
Screen printing is a system. When every step works together, from artwork to reclaim, you get better prints, fewer problems and more efficient production.
Key components of screen printing
The screen printing system
Screen printing works as a system. Each component plays an important role in the final print. Understanding how these parts work together will help you make better decisions, solve problems and produce consistent results.
Artwork
Clean, high-quality artwork is the foundation of a good print. Each color in the design requires its own screen.
Screens
The screen holds the stencil and mesh. Mesh count and frame type affect ink deposit, detail and print performance.
Stencils
The stencil blocks ink in non-image areas and allows ink to pass through the open image areas.
Inks
Different ink types are designed for specific garments, effects and production needs. Proper ink selection and handling are essential for consistent results.
Squeegees
The squeegee pushes ink through the mesh and controls ink deposit. Blade hardness, profile and angle all affect the print.
Press
The press holds the screens and garments, allowing you to print each color in sequence with consistent registration.
Dryers
Flash units and conveyor dryers cure the ink. Proper temperature and dwell time are critical for durability, washability and production speed.
Garments
Garment type, fabric content and surface condition affect ink adhesion, opacity and overall print quality.
Quick Fact
Changing just one component, such as mesh count, stencil thickness, or ink type, can affect ink deposit, print quality and curing. Always consider the entire system when troubleshooting or making adjustments.
Dynamic Perspective
Successful screen printing comes from understanding how all the components work together. Small adjustments in artwork, screens, ink, press setup or drying can make a big difference in print quality, efficiency and consistency.
