Optimization of the Image Profile Transform in High Resolution Electrophotography
For the purpose of constructing a method to resolve the above stated problems, we modeled image profile transforming properties, including the energy distribution of laser beam exposure, the latent image profile, and the profile of developed toner. The resulting image profile is related to such parameters as the exposure condition, PIDC (photo-induced discharge characteristics), which is the potential of the photoreceptor as a function of the exposure energy, and the development curve. Next, we defined the merit function of the target image profile. Employing this function, it was possible to choose the parameters in such a way to produce satisfactory results by using a nonlinear programming method. Finally, we performed experiments using 1200dpi resolution with the parameter values obtained through the optimization process and found that the developed image profile was satisfactorily sharp.

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.
