- Color Separation: For multi-color prints, each color requires a separate stencil or screen. Color separation involves isolating each color in the design to create individual masks.
- Scaling and Positioning: The design is scaled to the desired size and positioned correctly on the substrate.
2. Emulsion Coating
- Selecting the Mesh: The mesh count (number of threads per inch) is chosen based on the detail level and ink type. Higher mesh counts produce finer detail but allow less ink flow.
- Applying Emulsion: A light-sensitive emulsion is evenly coated onto the mesh screen in a darkroom or under subdued lighting. The emulsion dries in a dark, dust-free environment.
3. Exposure and Image Transfer
- Creating the Stencil: The artwork is printed onto a transparent film (with opaque areas corresponding to the design).
- Exposing the Screen: The coated mesh is placed under a UV light with the film on top. The light hardens the emulsion in unblocked areas, creating a stencil.
- Developing the Screen: After exposure, the screen is washed with water, removing the unhardened emulsion and revealing the stencil. The screen is then dried and inspected.
4. Printing Preparation
- Setting Up the Press: The screen is mounted onto a printing press, aligned precisely with the substrate to ensure accurate placement.
- Applying Ink: The appropriate ink—plastisol, water-based, solvent-based, or specialty inks—is poured or spread onto the screen.
5. Printing and Curing
- Squeegee Action: A squeegee is used to pull the ink across the screen, pushing ink through the open stencil areas onto the substrate.
- Multiple Colors: For multi-color prints, each color requires its own screen, and the printing process is repeated in registration.
- Drying and Curing: The printed items are passed through drying ovens or flash dryers to cure the ink, ensuring durability and washability.
6. Cleanup and Maintenance
- Removing Screens: After printing, screens are cleaned with appropriate solvents to remove residual ink and emulsion for reuse.
- Inspection and Quality Control: Final products are inspected for registration accuracy, color consistency, and print quality.
