INK JET PRINTING APPARATUS AND METHOD FOR ESTIMATING MOISTURE CONTENT OF PRINT SHEET

摘要

In an ink jet printing apparatus, a moisture content of a print sheet is estimated without decreasing productivity of the printing apparatus and appropriate conditions of printing operation in the subsequent printing process are specified. More specifically, by measuring a change in thickness of the print sheet after printing, a state of moisture content is estimated. Estimating a state of moisture content allows determination of appropriate conditions of the printing operation such as a minimum drying time required for printing a high-quality image on various types of print sheets such as print coated paper or coated paper.
