Variable Data Cylinder Printing
Abstract:There is a need for a fast digital printing technology that can be used in-line on an analogue printing press, initially for Variable Data on Press (VDOP) applications. Inkski Ltd has been developing a novel drop on demand technology, ‘Light Initiated Liquid Offset’ (LILO) based on the forming of ink drops on a rapidly rotating cylinder. This paper looks at the principles governing the LILO technology and the results achieved from this development, also outlining the technical challenges remaining. The performance characteristics of an offset lithography equivalent printing process are identified and compared to LILO and other digital printing approaches. The conclusion is that unmodified none of these approaches currently have the potential to achieve offset equivalent printing. We briefly introduce an evolution of the LILO technology, which may have the potential to provide an offset equivalent digital printing process.

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.
