Print quality inspection equipment

Ink monitor system

A system for monitoring ink flow from an ink storage tank to at least one ink fountain of a high-speed, web-fed printing press employing a scale for measuring the weight of the ink storage tank and comparing weight signals from the scale at successive times to determine the weight of ink consumed over the interval between readings. A pump is associated with the storage tank for pumping the ink to the fountain via coupling lines. An ink level sensor detects the level of ink in the fountain and provides an ink demand signal for operating a valve means in the ink coupling line to in turn cause ink flow to the fountain so as to provide replenishment of ink thereat. With the use of plural fountains, means are provided for prioritizing delivery to the fountains so that individual ink consumption on a per fountain basis can be determined. In this regard, the system also employs a volume sensor preferably in the form of a pump stroke position sensor for determining incremental weight delivery per stroke.

Method and printing system for gray balance correction of a printing process, computer program product and computer program storage device

A method and a printing system for gray balance correction of a printing process include determining first color values at on a gray axis of a color space of a reference printing process. These first color values determine tonal values describing a corrected gray balance of the target printing process. To avoid wastage and a further proof for gray balance calibration of the printing process, second color values of the printing process, describing the corrected gray balance, are derived from the first color values. The tonal values of the target printing process corresponding to the second color values are determined from first characterization data and the second color values of the printing process. A correction function created from these tonal values describes the corrected gray balance. Determining corrected characterization data is also possible. A printing form is produced and a printing material is imaged by using the corrected gray balance.
