Why Use High Density Silicone ?
High-density silicone is an excellent choice for screen printing on clothing, especially when you want a raised, textured, or durable print that stands out. Unlike traditional plastisol or water-based inks, silicone ink creates a flexible, rubber-like finish that's highly resistant to cracking, stretching, and washing.
Why Use High-Density Silicone for Screen Printing?
✅ Thick, Raised Prints – Creates a 3D puff effect without multiple layers.
✅ Extreme Durability – Withstands repeated washing, stretching, and abrasion.
✅ Soft & Flexible – Moves with the fabric without cracking.
✅ Heat & Water Resistance – Won't melt or degrade in high-heat washes.
✅ Vibrant Colors – Can be mixed with pigments for opaque, bright prints.
Best Applications for Silicone Screen Printing
Sportswear & Activewear (stretchy fabrics like polyester/spandex)
Workwear & Outdoor Gear (abrasion-resistant prints)
Fashion & Streetwear (bold, textured designs)
Promotional Apparel (long-lasting prints)
How to Screen Print with High-Density Silicone Ink
Mesh Screen: Use a low mesh count (40-80) for thick deposits.
Ink Preparation:
Silicone ink is usually ready-to-use (no mixing required).
Can be thinned slightly with silicone thinner if needed.
Printing Process:
Print 1-2 layers (no flash drying needed between layers).
Use high squeegee pressure (60-70° angle).
Curing:
Heat press or conveyor dryer: 150–170°C (300–340°F) for 1–2 minutes.
Must reach full cure for maximum wash resistance.

Pro Tips for Best Results
🔥 Pre-test on fabric – Some synthetics (like nylon) may need adhesion promoters.
🔥 Use adhesive spray – Helps prevent shifting during printing.
🔥 Avoid over-thinning – Can reduce opacity and durability.
🔥 Post-cure for extra durability – Some printers bake at 150°C for an extra 30 sec.
