Performansi Flash Curing Sebagai Pengering Tinta Sablon Dengan Daya 720 Watt

Abstract

T-shirt is a simple and lightweight garment worn on the upper body, suitable for people of all ages and commonly featuring printed designs. One of the most frequently used screen printing inks is plastisol ink. Plastisol ink is oil-based, which results in a longer drying time once applied to the fabric The most commonly used tool for drying screen printing ink is the hot gun, which can dry plastisol ink in approximately 14 minutes per shirt. Hot guns typically operate at power ratings ranging from 900 to 1800 watt. An alternative drying tool is the flash curing unit, which is designed with multiple integrated components capable of generating heat to cure screen printing ink applied to T-shirt fabric. The heating element used in this device can produce heat without emitting light. Heat is transferred to the surface of the ink via conduction and natural convection. In this study, temperature settings of 100°C, 150°C, 200°C, and 250°C showed similar drying behavior. The higher the power output of the heating element, the faster the drying process. Likewise, the closer the distance between the heating element and the ink surface, the shorter the drying time. The fastest drying time was achieved when the heating element was positioned 5 cm above the printed ink surface and operated at a power of 720 watt
