In this article, we will explore the characteristics of plastisol ink, its method of application, and the advantages it offers in the world of screen printing.

Understanding Plastisol Ink

Plastisol ink is a type of screen printing ink composed of PVC particles suspended in a plasticizing emulsion. Unlike water-based or solvent-based inks, plastisol ink does not dry through evaporation. Instead, it cures or solidifies when exposed to high temperatures. This unique property allows for greater control during the printing process, as the ink remains wet on the screen until heat is applied.

Method of Application

1. Preparing the Screen: Start by preparing the screen for printing. Coat the screen with emulsion, expose it to UV light using a film positive of the desired design, and wash away the unexposed emulsion to create the stencil.

2. Mixing and Preparing the Ink: Plastisol ink typically comes in a range of vibrant colors. Before use, thoroughly mix the ink to achieve a consistent texture and ensure even distribution of the pigments. Some inks may require additives or thinners to achieve the desired viscosity.

3. Loading the Screen: Place the prepared screen onto the printing press. Apply a generous amount of plastisol ink onto one end of the screen and use a squeegee to evenly distribute the ink across the design area, making sure to apply sufficient pressure to push the ink through the stencil.

4. Printing the Design: Once the ink is evenly distributed, use the squeegee to make a firm, smooth pass across the screen, transferring the ink onto the substrate. Repeat the process for each print, ensuring consistent pressure and ink coverage.

5. Curing the Ink: After printing, the ink needs to be cured to achieve durability and permanence. Plastisol ink requires exposure to high temperatures, typically around 320°F (160°C), using a heat press or conveyor dryer. The heat cures the ink, creating a strong bond with the substrate.

 

Advantages of Plastisol Ink

Vibrant and Opaque: Plastisol ink offers excellent color vibrancy and opacity, resulting in bold and eye-catching prints. The ink sits on top of the substrate, creating a smooth, opaque finish even on dark or colored fabrics.
