Screen printing with silicone ink and plastisol ink involves different materials and processes, each with its own properties and uses. Here's a comparison:
Silicone Ink
Composition: Made from silicone polymers, which are flexible and durable.
Curing: Cures at lower temperatures than plastisol, reducing energy costs and fabric damage.
Elasticity: Highly elastic, making it ideal for stretchable fabrics like sportswear.
Feel: Provides a soft, smooth finish.
Environmental Impact: More eco-friendly, as it doesn't contain PVC or phthalates.
Durability: Excellent resistance to heat and washing; maintains color vibrancy.
Application: Often used in high-performance and athletic apparel.
Plastisol Ink
Composition: Made from PVC particles suspended in a plasticizer.
Curing: Requires higher temperatures to cure, which can affect some fabrics.
Elasticity: Less elastic than silicone, but still offers good coverage.
Feel: Can be thicker and more rubbery, depending on application.
Environmental Impact: Contains PVC and may include phthalates, which raise environmental concerns.
Durability: Good durability and opacity; holds up well over time.
Application: Widely used for general screen printing on various textiles.
Summary
Silicone ink is ideal for applications requiring stretch and environmental considerations.
Plastisol ink is versatile and commonly used for more traditional screen printing needs.
Choosing between them depends on the specific requirements of the project, including fabric type, desired print feel, and environmental considerations.
