Basic Study on Effects of Water Content of Printing Paper on Thermal Conductivity

Abstract

This paper describes a relationship between water content and thermophysical properties of printing papers. The general printing paper consists of lots of plant fibers. Hence the printing papers are open to influence of humidity. Due to the effects of humidity and surrounding temperature, the physical properties of the printing papers are affected and this causes change of the printing quality. In this report, in order to achieve an optimization of the printing process for the reduction of power consumption while improving the printing quality, we tried to evaluate the relationship between thermal conductivity of the printing paper and the water content. Especially, by using the combination of the steady state absolute thermal conductivity measurement method and Modelica simulation, we evaluated the effects of water content on thermal conductivity quantitatively.
