Properly Curing Plastisol Ink on Your Garments

Curing plastisol ink is the most critical step in screen printing—if you don't get it right, your hard work literally washes down the drain. While it might look dry to the touch, achieving a full chemical bond requires reaching specific internal temperatures to ensure durability and wash-fastness.

Whether you are using a professional conveyor dryer or starting out with basic tools, understanding the balance between time and temperature is key to professional results.

Quick Curing Essentials

• Standard Plastisol: Typically requires reaching a temperature of 320°F throughout the entire ink film.
• Low-Cure Inks: Specialized products like Dynamic Ink are designed to cure at lower temperatures (around 270°F - 280°F), which is ideal for heat-sensitive synthetic fabrics.
• The Stretch Test: A simple way to check your work; if the ink cracks when pulled, it hasn't reached the necessary temperature.
• Monitoring Tools: Using >Thermo-Tel Strips or an Infrared Thermometer Gun allows you to track heat levels accurately without guessing.

Mastering these basics prevents common issues like dye migration on polyesters or "under-cured" prints that flake off after the first wash.
