screen printing on plastic

Screen printing on plastic has become a popular and versatile method for applying vibrant designs, logos, and graphics to a wide range of plastic products. From promotional items to packaging materials, screen printing offers durability, flexibility, and exceptional print quality. In this article, we will explore the process of screen printing on plastic, its advantages, applications, and the key factors that contribute to successful outcomes.

The Screen Printing Process:

Preparing the screen: A fine mesh screen is coated with a photosensitive emulsion and dried. The desired design is then transferred onto the screen using a film positive.

Creating the stencil: The screen is exposed to UV light, hardening the emulsion except where the design blocks the light. The unexposed emulsion is rinsed away, creating a stencil.

Ink application: The stencil is placed over the plastic substrate, and ink is applied to the screen. The pattern is transferred to the plastic by pressing the ink through the mesh using a squeegee.

Curing: The printed plastic is then cured at high temperatures or with UV light, ensuring the ink adheres permanently to the surface.

Advantages of Screen Printing on Plastic:

Durability: Screen printing on plastic offers excellent durability, making it ideal for products that require resistance to scratching, fading, and exposure to various environmental conditions.

Vibrant colours: The process allows for the use of vibrant and opaque inks, resulting in eye-catching designs that stand out on plastic surfaces.

Versatility: Screen printing can be applied to various types of plastic, including rigid and flexible materials, offering flexibility in terms of product selection.

Customization: Screen printing allows for precise and intricate designs, making it suitable for creating custom logos, artwork, and detailed graphics on plastic items.

Applications of Screen Printing on Plastic:

Packaging materials: Screen printing is commonly used to enhance the visual appeal of plastic packaging, such as bottles, containers, and bags, providing branding opportunities and product differentiation.

Promotional items: Plastic promotional items like pens, keychains, and phone cases benefit from screen printing, as it allows for the incorporation of logos, slogans, and intricate designs.

Electronic devices: The screen printing process is employed in the production of electronic devices, including control panels, displays, and casings, adding visual elements and labelling information.

Automotive industry: Screen printing on plastic is utilized in automotive applications, such as dashboard components, interior trims, and exterior emblems, providing branding and decorative options.

Factors for Successful Screen Printing on Plastic:

Substrate preparation: Proper cleaning and surface treatment of the plastic substrate are crucial to ensure ink adhesion and long-lasting print quality.

Ink selection: Choosing the right ink formulation, compatible with the plastic material and desired print outcome, is essential for achieving optimal results.

Mesh selection: The selection of the appropriate mesh count and thread diameter of the screen plays a significant role in determining the level of detail and ink deposit.

Curing process: Adequate curing ensures the ink bonds effectively with the plastic surface, ensuring durability and resistance to abrasion and environmental factors.


Screen printing on plastic offers a powerful solution for adding vibrant designs and graphics to a wide range of plastic products. Its durability, versatility, and exceptional print quality make it a preferred choice for industries such as packaging, promotions, electronics, and automotive. By understanding the screen printing process and considering crucial factors, businesses can harness the power of screen printing to create visually striking and durable plastic products that leave a lasting impression.
