International Classification:

G01N 21/86
G01V 8/00

US Classification:

25055939, 356429, 358474

Abstract:

An inspection system for inspecting an imprinted substrate on a printing press has a light source, a contact image sensor, and a processor. The light source is configured to illuminate a portion of the substrate which has been imprinted with different colors at a plurality of printing units of the printing press. The contact image sensor has a plurality of sensing elements. Each sensing element senses light reflected by a corresponding region on the substrate to produce data representative of the corresponding region printed on the substrate. The processor is configured to receive the data representative of the imprinted substrate and to compare the data representative of the corresponding region printed on the substrate with stored reference data.

US Classification:

25055939, 356429, 358474

Abstract:

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.
