In previous publications we have demonstrated the use of laser intensity modulation to embed information in halftone and text documents. In those experiments we were able to embed and correctly decode 33 bits in a 12 point page of printed text. In this paper we will present our current work on developing a channel model for a text document. This model will allow us to define capacity bounds for the channel and to better understand the modulation and detection techniques that can be used to reach that capacity.

  • 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.
