To provide an original reader/recorder capable of recording a predetermined region with a dropout color.

When picture data including a predetermined mark 200 is received, the picture data other than a predetermined region shown by the prescribed mark 200 is recorded on recording paper as usual by a recording part, and picture data of the predetermined region shown by the predetermined mark 200 is recorded on the recording paper in a preset dropout color (green). In this case, even if the image data of the predetermined region is set to any color, the picture data is recorded on the recording paper in the preset dropout color. Since the predetermined mark 200 is a mark for recording the data of the predetermined region in the dropout color, the predetermined mark 200 itself is not recorded on the recording paper. Then, the attachment of the predetermined mark 200 can record the predetermined region on the recording paper in the dropout color when an original is prepared with a personal computer.
