Abstract
A printing sheet is made from a porous resin sheet containing a predetermined amount of carbon grains. In order to manufacture the printing sheet, a mask (which partially shields the infrared rays according to a predetermined pattern) is placed on a transparent plate and the printing sheet is placed on the mask sheet. Flash bulbs irradiate the infrared rays onto the mask sheet. Infrared rays irradiated onto the transparent portion of the mask sheet pass through the mask sheet and reach the printing sheet, causing the carbon grains to heat the resin sheet such that pores in said resin sheet are sealed to form a non-print portion on said porous resin sheet corresponding to said transparent portion.
