JENIS - JENIS SCREEN SABLON MANUAL & FUNGSINYA ( SCREEN SABLON 101 )

Introduction

This tutorial explores manual screen printing techniques, focusing on the different types of screen printing and their applications. Originating from China, this method has evolved and adapted across cultures, allowing for a variety of materials to be printed on, such as fabric, glass, and paper. Understanding these techniques will enhance your printing skills and open up new possibilities for your projects.

Step 1: Understanding Screen Printing Basics

• Definition: Screen printing involves transferring ink through a mesh screen onto a substrate.
• History: This technique was first developed in China between 960 and 1279 AD and has since spread globally, evolving into various modern methods.
• Applications: Commonly used for printing on textiles, glass, plastics, and more.

Step 2: Types of Screen Printing Techniques

Familiarize yourself with various screen printing methods:

• Manual Screen Printing: Traditional method using hand-operated screens, ideal for small runs.
• Automatic Screen Printing: Machine-operated, suitable for larger production volumes.
• Specialty Techniques:
  • Sablon Kaos: T-shirt printing.
  • Sablon Gelas: Glass printing.
  • Sablon Plastik: Plastic printing.
  • Sablon Kertas: Paper printing.

Step 3: Selecting the Right Screen and Ink

Choose the appropriate materials for your project:

• Screens: Consider mesh count and material type based on the print detail needed.
• Inks: Use inks formulated for specific substrates (e.g., water-based inks for fabrics, solvent-based for plastics).

Step 4: Preparing Your Workspace

Set up an efficient printing area:

• Ensure the workspace is clean and well-ventilated.
• Gather all necessary tools: screens, squeegees, inks, and substrates.
• Have a drying area ready for printed items.

Step 5: Printing Process

Follow these steps for successful screen printing:

1. Design Preparation:
   • Create your design digitally.
   • Print the design onto a transparency for exposure.
2. Screen Exposure:
   • Apply emulsion to the screen and let it dry.
   • Place the transparency on the screen and expose it to UV light.
3. Washing the Screen:
   • Rinse the screen with water to reveal your design.
4. Setting Up for Printing:
   • Place your substrate beneath the screen.
   • Align the screen properly.
5. Applying Ink:
   • Pour ink at the top of the screen.
   • Use the squeegee to press ink through the mesh onto the substrate.
6. Drying:
   • Allow printed items to dry completely before handling.

Common Pitfalls to Avoid

• Insufficient Screen Exposure: Ensure the emulsion is properly exposed to avoid incomplete designs.
• Misalignment: Double-check that your screen is aligned with the substrate before printing.
• Ink Consistency: Use the right ink for the substrate to prevent smudging or fading.

Conclusion

Manual screen printing is a versatile technique that can be applied to various materials and projects. By understanding the different types of screen printing, selecting the right tools and materials, and following a structured printing process, you can achieve professional-quality results. Consider experimenting with different methods and materials to expand your skills further.
