Abstract

See full text

A method of signaling or indicating a coloration condition upon a change of an operating condition in a printing press having a control unit, includes the steps of specifying a target ink density for a print job, storing the specified target ink density in the control unit, calculating an actual ink density using the control unit based on an actual operating condition of the printing press, comparing the actual ink density to the target ink density in the control unit, and emitting a first signal using the control unit when the actual ink density is within a range of tolerance about the target ink density stored in the control unit.
