Abstract
Recently, coated steel plates are attracting attention for application in interior and exterior materials. Among the various methods for manufacturing coated steel plates, inkjet printing method is an emerging technology since it can form various patterns on substrates. Ink application necessarily involves a drying process. In this study, we explored the possibility of induction heating instead of hot air drying, which is mainly used in the drying process for ink coated on a substrate. First, an induction heating system was set up and drying experiments were carried out using a solvent ink and an eco-solvent ink. Although the results were slightly different depending on the solvent content, induction heating showed the best adhesion performance. Similar results were obtained when a Ag ink was used. Therefore, we insist that induction heating is the best drying method for steel substrates that can be heated differently than polymer substrates.
