ABSTRACT:
A display system for a rotary printing press for displaying the inking profile on an LED matrix. The profile indication is provided by means of a time shared display with control circuit which scans the positions of all the ink control members, all having position sensors, and sequentially accesses an analog-to-digital converter with decoded outputs which are converted to a number of LED columns, each represented by a continuously lighted LED the coarse position of the ink control member. A fine position indication may be provided by simultaneously showing a fine indication by means of a flash LED in the corresponding column. A still finer indication may be provided by means of a second flashing LED in the corresponding column.
