An Aqueous UV Curable Inkjet Printing for Graphic Output
Abstract:The material design concept for aqueous UV curable inkjet inks and quality of graphic output are explained. The UV fixing in inkjet printing has already been realized by several kinds of products. Almost all these printing systems are based on the piezo electric print head by non-aqueous UV inks and designed to print on non-absorbing substrates. The ink system of this article is characterized as composition of water-soluble photo-initiator and water-soluble oligomers in aqueous pigment dispersions. The objectives of the system are to adopt the bubble & thermal inkjet system and to print mainly on absorbing substrates. How we design the water-soluble materials and design parameters are discussed. How we can control and realize the quality of graphic output by pigmented inks is also presented. Although the aqueous based system has disadvantage on curing speed; it will enable us to realize printer which is more environmental and also to create a graphic output close to current commercial printing.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
