Research of Inkjet Printing of Water-Based Inkjet Ink for the Curved Surface

Abstract

Products with various shapes and curvature have been attracted a lot of attention with the improvement of individual requirements and the development of 3D printing technology. Traditional methods of printing are applied to decorate products with regular surface. However, it is difficult to realize the decoration of products with complex curved surface. There is no doubt that inkjet printing technology is the best way to decorate products with curved surface. The development of environmentally friendly water-based ink is important for applications of inkjet printing. Water-based ink, has anti-clogging capability and suitable properties such as viscosity and surface tension, is suitable for inkjet printing. In this paper, preparation and properties of water-based soft ink and hard ink were analyzed and discussed. Then, water-based inkjet ink with environmental protection and well printability was obtained through the selection of type and content of water-based resin, water-based color paste and other additives. The water-based inkjet ink can be used to decorate products with complex curved surface by inkjet printing technology.
