UV Curing of Inks and Coatings in Digital Printing Applications
Abstract:UV curing of inks and coatings is discussed in relation to the type of UV source and curing systems available for use in digital printing applications.
Comparison is made between classic arc, microwave powered UV and LED technologies. The advantages and limitations of each are critically reviewed for curing the wide range of materials as used in both the graphic arts and industrial processes.
Factors influencing cure are identified by detailed consideration of material and process. Variables include chemistry, substrate types, application requirements and optical design / spectral emission of the curing system. A method of lamphead characterisation is outlined using computer ray trace tools and dosimetry measurement techniques, with view to maximising dose efficiencies and optimising curing performance.
Selection of the most appropriate type of curing system is concluded as being based on simple cost to performance ratio for the given application.

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.
