[Sovereign Items] 1. An ink amount control device of a printing press, which determines the opening degree of the ink fountain key based on a predetermined conversion curve from the image area rate, and presets the ink fountain key to the aforementioned opening degree before performing printing. When the average value of the image area ratio of each area is greater than or equal to the predetermined value, the normal mode is set. On the other hand, when the predetermined value is less than the predetermined value, the small image mode is set, and in the small image mode, the transfer is performed during printing. The frequency of the contact frequency of the ink roller is smaller than that of the normal mode, and at the same time, for the preset before printing, the ink fountain key is turned on in accordance with the increase in the image area ratio as compared with the main conversion curve used in the normal mode. The degree of increase in the rate of correction of the larger transformation curve to the ink button.

[Abstracts] The present invention provides an ink amount control apparatus for a printer capable of expressing the hue of an image with high accuracy compared with the related art only when there is an image on a part of the paper surface. When the average value of the image area ratio of each area is less than the predetermined value, the small image mode is set. In the small image mode, the number of contact times of the ink transfer roller at the time of printing is set to be smaller than that in the normal mode. In addition, the preset before printing is performed according to the main conversion curve used in the normal mode. In the correction conversion curve where the increase in the image area ratio and the increase rate of the opening degree of the ink fountain key is large, the ink fountain key is preset.
