Abstract
A display apparatus for facilitating adjustment of a printing press displays several quantities related to the inking of the printing press in a display that is arranged to show a functional relationship between the quantities. The settings of a plurality of ink adjustment devices are shown in a linear array of setting displays that are arranged in the same order as the adjustment devices are arranged across the width of the press. Each setting display comprises a column of equally-spaced dots with an interpolation dot at the end of the column. In vertical alignment with and in appropriate lateral relationship with that display of settings, a further display is provided showing deviations of the printed ink density from set points representing proper ink density. Each deviation display corresponds to a lateral portion of the press whose printed ink density is controlled by the settings of those of the adjustment devices with whose setting display it is aligned.
