The majority of Non-Impact Printing applications currently use lasers as their light source. In order to generate a pattern on the media of interest these laser sources must be coupled with an imaging engine.

Using an array of LEDs as the light source combines the imaging engine with the light source, making all the components solid state. This leads to a higher degree of integration and ease of manufacturability.

Some products are available demonstrating the viability of LEDs arrays as the imaging source and engine.

This paper presents advances in LED technology that will enable LED arrays to replace other light sources as well as the imaging electronics in a manner that provides the advantages of lower power, higher speed and higher resolution (addressability).

InfiniLED has demonstrated high density monolithic individually addressable μLED arrays that can be assembled to provide a single line of emitters for A4 or wider non-impact printing applications. We present the micro-led array technology and describe how it can increase performance and quality in non-impact printing while decreasing cost.

  • 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.
