Ink Drying and Curing

- Accelerating Drying Speed: In screen printing operations, one of the key challenges is often the drying time of the printed ink. This halogen infrared heat lamp, with its 1200w power, can significantly accelerate the drying process. When ink is printed onto various substrates such as fabric, paper, plastic, or metal, the heat lamp emits infrared radiation that quickly heats the ink, causing the solvents within it to evaporate rapidly. For example, on a large batch of printed T-shirts, instead of waiting hours for the ink to dry naturally, the heat lamp can reduce the drying time to just a few minutes, allowing for faster production throughput.
- Ensuring Complete Curing: For certain types of inks, especially those that require a curing process to achieve their full hardness, adhesion, and durability, the heat lamp plays a crucial role. The infrared heat penetrates the ink layer, promoting the cross-linking of the ink components. This is particularly important for UV-curable inks or high-performance inks used in industrial screen printing. By ensuring complete curing, the printed products have better resistance to abrasion, scratching, and fading, resulting in a higher quality finish.
Substrate Preparation

- Preheating Substrates: Before the actual screen printing process begins, preheating the substrate can have several benefits. The heat lamp can be used to warm up substrates like fabrics or plastics. For fabrics, preheating can reduce moisture content, making it easier for the ink to adhere and penetrate the fabric fibers. In the case of plastics, preheating can improve the surface energy of the plastic, enhancing the adhesion of the ink. For example, when printing on a polyester fabric, preheating it with the heat lamp can result in a more vibrant and long-lasting print.
- Removing Surface Contaminants: The heat generated by the lamp can also help in removing certain surface contaminants from the substrate. As the substrate is heated, some light oils, dust, or other impurities may vaporize or become more easily removable. This ensures a cleaner surface for printing, which in turn improves the quality of the printed image. For instance, on a metal substrate that may have a thin layer of oil residue, the heat lamp can help to burn off or loosen this residue before printing.
