No. 01, No. 5-11105, No. 200
Japanese Patent Laid-Open No. 0-48716 discloses a method of continuously applying ink to a running sheet using a stripe coater die coater having a large number of ink jet nozzles.

However, in this coating method using a die coater, when a fine pattern having a width of 1 mm or less is formed on a sheet, if the ink is directly attached to the sheet, the ink is likely to wet and spread on the surface of the sheet and a highly accurate stripe is stabilized. Then, it is difficult to form.

Therefore, measures such as using an ink having an extremely high viscosity and imparting to the ink a property of curing immediately after coating have been proposed, but none of them has been established as a sufficient measure.

Further, in the coating method using a die coater, it is necessary to manufacture a die coater equipped with a large number of jet nozzles having an extremely fine diameter, which causes a problem that the equipment cost of the pattern sheet manufacturing apparatus becomes high. There is also a problem that the ejection nozzle is easily clogged with ink.

In view of the above circumstances, it is an object of the present invention to provide a pattern sheet manufacturing method and manufacturing apparatus capable of manufacturing a pattern sheet at low cost by a continuous process.
