A High-Resolution Laser Thermal Lenticular Printer
In this paper, we present a novel method for generating lenticular images based on the laser thermal process. A highpower infrared multimode laser is used to thermally transfer dyes from three donor sheets (cyan, magenta, and yellow) to a lenticular card. The beam is oriented and aligned to the cylindrical lenses to allow a minimum spot size in the cross lens direction. The printing resolution is asymmetric at approximately 2500 by 300 dpi. This method allows the printing of 10 micron continuous tone lines, which yields 34 images behind a 75 lenses per inch substrate. Printing occurs in alignment with the lenticules by premeasurement, rotational alignment, and adjustment of relevant parameters.
The printed card is then thermally laminated with either a transparent or reflective backing, which acts as a receiver and protection. The current printer allows individual cards to be printed in less than 5 minutes. Samples will be presented, which show the high-quality motion and stills possible by this process.

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.
