Evaluation of Binder Effectiveness in Enhancing Foil Adhesion on UV Inkjet Printed Surfaces.

Foil coating technology is a crucial process that enhances the value of printed materials. Across the global printing industry various techniques have been developed to create diverse surface textures and aesthetic effects to meet the demands of both printing businesses and consumers. However current foil coating processes still face challenges such as incomplete adhesion uneven coating and material limitations that affect print quality. To address these issues continuous advancements in foil coating technology have been made including the development of digital foil printing systems that offer high precision and streamlined production processes. However the high cost of these systems remains a significant barrier for small and medium-sized enterprises (SMEs). Inkjet printing has emerged as an alternative solution to reduce costs by utilizing adhesion promoters such as primers or toner-based methods to enhance foil adhesion. Despite its advantages this technology has yet to gain widespread adoption in the Thai printing industry due to its complex production process and the need for specialized expertise. Nevertheless, the print quality achieved through this method is comparable to that of digital foil printing. This study aims to explore the development of foil printing processes within the context of the Thai printing industry seeking efficient and costeffective solutions for future implementation.
