According to the latest survey by the Specialty Graphic Imaging Association, screen printing is identified as one of the most lucrative businesses in the graphics industry, accounting for about 27.4% of the total market share. This time-proven method has been used for decades. It is a relatively straightforward process that allows for high-quality, vibrant prints on various materials like fabric, paper, glass, metal, and plastic. Here is a detailed guide on how screen printing works.

What Is Screen Printing?

Screen printing is also known as silk screening or serigraphy. This technique uses fabric screens to apply layers of ink onto a printing surface. The process involves creating an original screen by placing a stencil over the screen and forcing ink through this screen onto the material underneath. Each color in your design requires its own screen, which means that complex multi-colored patterns can be somewhat challenging to produce.

The Process Of Screen Printing

In a typical screen-printing process, five main steps are involved; creating the design, creating the screens, setting up the press and screens, actual printing, and drying and curing of the final product.

Creating The Design

The first stage involves developing a design for printing. The design is created using computer software like Adobe Photoshop or Illustrator. Once the design is complete, it is printed onto a special film that is transparent where ink should be applied on the final product.

Creating The Screens

The next step is to make screens corresponding to each color present in your design. A mesh screen stretched on a frame is coated with light-reactive emulsion and then dried. The film for each color of your design is placed onto these coated screens and exposed to bright light. This light hardens the emulsion that is not covered by your design, leaving a stencil of your design on the screen.

Setting Up The Press And Screens

The screens are then placed into a press, which holds them at a predetermined location and angle concerning the printing surface. Each screen’s position must be carefully adjusted to ensure that all colors align correctly on the printed product. After placing the screens on the press, the ink is poured onto each one of them.

Actual Printing

The actual printing begins once everything is set up. The material or item to be printed, such as a t-shirt, is placed under the first screen. Using a squeegee, the screen printer spreads ink across the screen, forcing it through the mesh and applying it to the material underneath. This process is repeated for each color until all colors have been applied to the material.

Drying And Curing Of The Final Product

Last but not least, the final product is dried and cured to make sure that the ink will not fade or deteriorate over time. Depending upon the type of ink used, this may involve heating the material to a particular temperature for a specific period. Once this stage is complete, you should have a finished product with a high-quality, durable print.

Why Choose Screen Printing?

Screen printing has several advantages over other printing methods. Firstly, it produces very high-quality results with vibrant colors and excellent durability. This makes it ideal for applications such as t-shirt printing where appearance and longevity are important. Secondly, once the screens have been created, screen printing can be done quickly and efficiently, making it cost-effective for large orders. Finally, screen printing can be done on various materials and surfaces, giving it broad application potential.


In conclusion, screen printing is a versatile and practical method for creating high-quality prints on a variety of surfaces. From the initial design stage to the final curing process, each step is crucial in producing a durable and vibrant final product. Despite some challenges in setting up and aligning screens, the process is highly efficient for large orders. Whether you are looking to start your own screen-printing business or simply want to understand the process behind this popular printing technique, understanding how screen printing works gives you a fascinating insight into this enduring craft.

Frequently Asked Questions (FAQs) About Screen Printing

1. What is screen printing?

Screen printing, also known as silk screening or serigraphy, is a printing technique that uses fabric screens to transfer ink onto various materials through stencils.

2. What materials can be used for screen printing?

Screen printing can be performed on a variety of materials, including fabric, paper, glass, metal, and plastic.

3. How many colors can I use in a screen-printed design?

You can use multiple colors; however, each color requires a separate screen. Complex designs with many colors may increase the complexity and cost of the printing process.

4. Is screen printing durable?

Yes, screen printing is known for producing prints with vibrant colors that are very durable and long-lasting, especially when properly cured.

5. Can I print photographs using screen printing?

While it’s possible to print images that resemble photographs through halftone printing, screen printing is generally better suited for bold graphics with solid colors rather than detailed photographic images.

6. How long does the screen printing process take?

The time required for screen printing depends on the complexity of the design and the quantity of items being printed. Once the screens are set up, the actual printing process can be quite fast.

7. What kind of inks are used in screen printing?

Various types of inks can be used in screen printing, including plastisol, water-based, and discharge inks. The choice depends on the material being printed on and the desired effect.

8. Is there a minimum order quantity for screen-printed items?

Minimum order quantities vary among print shops. Screen printing is most cost-effective for larger orders due to the setup involved in creating screens for each color.

9. Can I reuse screens for different designs?

Screens can be cleaned and reused for new designs after removing the old emulsion. However, you cannot use the same stencil for different designs.

10. What is the curing process in screen printing?

Curing is the process of drying and solidifying the ink on the printed material to ensure it is set permanently. This often involves heating the material to a specific temperature.

11. Why choose screen printing over other printing methods?

Screen printing offers high-quality results with vibrant colors and excellent durability. It’s cost-effective for large orders and versatile across different materials.

12. Is screen printing environmentally friendly?

The environmental impact depends on the type of ink used and how waste is managed. Water-based inks are generally more eco-friendly than plastisol inks.

13. How do I care for my screen-printed items?

Care instructions may vary based on the ink and material but generally include washing inside out in cold water and avoiding harsh detergents or high heat that could damage the print.

14. Can I perform screen printing at home?

Yes, with basic equipment and supplies such as a frame, mesh, emulsion, ink, and a squeegee, you can perform simple screen-printing projects at home.

15. What software is recommended for designing a screen print?

Professional design software like Adobe Photoshop or Illustrator is commonly used to create precise designs that are then transferred onto transparent films for creating stencils.
