Primers for UV Jet-Inks
Abstract:As the range of applications for UV jet-ink printing expand, the diversity of media evolves at a similar rate. To adapt to this, in many situations it is possible to successfully modify ink chemistries or process conditions. However, in the case of medium to highly porous media, such as paper, output issues can remain. In particular, penetration of UV jet-ink can lead to insufficient optical density, poor image quality and high residual odour due to incompletely cured materials. In addition, equivalent image quality is often demanded across a selection of papers of varied nature. This article describes the usage of classes of primers that can be applied to papers and used in conjunction with UV jet-ink. In doing so, ink penetration can be minimised and controlled image quality may become possible. Specific examples are given for paste-UV and water-based UV primers which due to their curable functionality make them highly compatible with UV jet-inks. Furthermore, this approach to controlled ink wetting on porous media can be extrapolated to non-porous media such as plastic films. In doing so, this presents a combined matching of ink and primer chemistries to achieve desired wetting characteristics. In turn, this can help fulfill future demands in this market as it evolves.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
