In this paper, we demonstrated the feasibility of embedding unperceivable code sequence by modulating dot gains through laser intensity modulation for halftone images. From a communication systems point of view, a printer and a document scanner form the physical layer of a communication channel, where information can be hidden in halftone images and reliably transmitted and extracted. In the proposed approach, we will leverage our previous results in embedding unperceivable banding signals to halftone images and develop an integrated embedding and detection algorithm to embed and extract information with high payload capacity. Specifically, we will characterize the embedding capacity and detection rate associated with the proposed algorithm. Preliminary experimental results will be presented.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
