Study of 1200dpi High Resolution Thermal Print Head
Abstract:This paper is intended as an evaluation of a high-resolution thermal print head exceeding 600dpi. In the preceding paper we reported on the optimum structure and shape for 600dpi-head based on a series of experiments on thermal diffusivity of various materials possibly used as components. In the process of development we reached a two-ply structure consisted of a Si-single-crystal substrate superior in heat conductivity and a low thermal diffusion layer sputtered over the substrate. Carrying out FEM analysis of a 1200dpi-head of the above structure, we came to the conclusion that high resolution up of to 1200dpi was technically achievable. We also confirmed the possibility through print test.

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.
