Abstract
A printing press system with water content sensing capability is disclosed. Many printing operations, including keyless or lithographic printing presses, use an emulsion of ink and water to perform the printing operation. It is important that the emulsion maintain a proper balance between the ink and water. The disclosed system employs a sensor which may be placed in the ink train of the printing press to constantly monitor the level of water within the emulsion. The sensor may be a capacitive type sensor which detects changes in the dielectric constant of the emulsion, and based on a comparison of the measured value and a predetermined desired value, prompts the press operator regarding the imbalance to enable corrective action to be taken.
