    • An ink supply amount adjustment method for a printing press includes steps of measuring the density value of each density measurement patch printed in a range corresponding to each ink fountain key on a printed printing sheet, obtaining the opening ratio of each ink fountain key in preliminary ink feeding, based on the difference between the measured density value of a patch and a preset reference density value, and the current opening ratio of each ink fountain key or image data in the range corresponding to each ink fountain key, and performing the ink feed operation of an ink ductor roller while printing is suspended, after setting the opening ratio of each ink fountain key to the obtained opening ratio in preliminary ink feeding. An ink supply amount adjustment apparatus for a printing press is also disclosed.
    • 用于印刷机的供墨量调节方法包括以下步骤:测量印刷在与印刷的印刷纸上的每个墨斗键相对应的范围内的每个浓度测量贴片的浓度值,从而获得初步墨水中每个墨斗键的开口率 基于补片的测量密度值与预设参考密度值之间的差异,以及在与每个墨斗键相对应的范围内的每个墨斗键或图像数据的当前开启比,并执行墨水供给操作 在将墨水喷泉键的开口率设定为预备供墨中获得的开口率时,打印暂停时的墨水导向辊。 还公开了一种用于印刷机的供墨量调节装置。
