three-color gray

three-color gray (In French gris trichrome) gray tone obtained when the three chromatic printing inks CMY are printed together. Since three-color gray reacts particularly sensitively to changes in the inking metering of a printing press, the gray balance is especially suitable for quality control in production printing and basically also in setting up. System Brunner invented the control strategy with gray balance priority, and optimized it with Instrument Flight (the full version is also available with KBA QualiTronic Color Control or with QTI CCS).
