发明名称 Imaging an imprinted substrate on a printing press using an image sensor
摘要 Systems and methods for imaging an imprinted substrate on a printing press is provided. One method comprises sensing light reflected by the substrate using a contact image sensor to produce data representative of the imprinted substrate. The substrate has been imprinted with different colors at a plurality of printing units of the printing press. Each printing unit comprises a plate cylinder. The data representative of the imprinted substrate is output by the contact image sensor as analog voltage signals. The method further comprises receiving the analog voltage signals from the contact image sensor at a sensor interface circuit and converting the analog voltage signals to digital signals using an analog-to-digital converter of the sensor interface circuit. The method further comprises processing the digital signals using the sensor interface circuit to produce corrected digital signals and storing data based on the corrected digital signals in a memory.
