Abstract
A coating method is performed by positioning a coating roll directly beneath one end of a predetermined coating range of a printing roll so that the coating roll is perpendicular to the printing roll. The rotating roll rotates and carries a coating liquid which is to be coated on the printing roll that is held horizontally. The printing roll is rotated, and the coating roll is also rotated in a direction in which the carrying of the coating liquid takes place on a leading side of the rotating roll with respect to the traveling direction of the coating roll. The coating roll and is moved from one end to the other of the coating range on the printing roll in such a manner that the coating roll is kept in contact with the printing roll and the coating liquid is coated on the printing roll.
