Abstract
In a method of correcting a position of each ink fountain key, a position of an ink fountain key is set as a present position with reference to a home position by using print data including an image area ratio of a reference plate having a predetermined image. A printing product is printed by using the reference plate with the ink fountain key being set at the present position. A density of each of respective areas, corresponding to the ink fountain keys, of the obtained printing product is measured. One of the home position and the present position of the ink fountain key is corrected on the basis of a difference between the measured density of the corresponding area and a reference density stored in advance. A position correcting apparatus is also disclosed.
