As outlined in the Screen Printing ASPA article “Curing a Screen Print,” plastisol ink requires a precise curing process to ensure durability. The ink must reach 320°F throughout the entire deposit—not just feel dry on the surface. A print that isn’t fully cured will fail during washing, leading to costly returns and dissatisfied customers.
While flash cure units can be a viable solution for shops with limited budgets, they require careful monitoring to ensure proper curing. These units can act as entry-level tools, effectively simulating the heating elements found in professional conveyor dryers. However, for consistent and scalable operations, a textile dryer is the ideal choice, offering automated, reliable curing through a belt-driven heating chamber.
By investing in the right equipment and adopting proper curing techniques, screen printers can ensure high-quality, long-lasting results, avoiding the risk of undercured prints.
