PROBLEM TO BE SOLVED: To provide a method for coating a sheet capable of coating so that a difference in density appears sufficiently. SOLUTION: This method for coating the sheet intermittently sprays a coating material 4 from a spray nozzle 2 aligned in many rows in a direction orthogonal to a transfer direction of the sheet 1 which is a substance to be coated on the sheet 1 by the opening and closing of a needle 3 of the spray nozzle 2 so as to become a roughly circular spray pattern P, and also adjusts an amount of the coating material 4 by controlling the opening time of the needle 3 of the spray nozzle 2 to impart a shade to a coating color. In this method, the coating is carried out using the coating material 4 having a viscosity of 15-30 seconds by an Iwata cup (s/20°C). COPYRIGHT: (C)2006,JPO&NCIPI
