Example Embodiment

[0018] An online quality inspection system for printed matter. The system consists of a 3CCD camera, LED-array light source, zoom lens, MV-600 high-speed / high-precision industrial image capture card, PC platform hardware and image processing software.

[0019] This system uses a 3CCD camera to replace the human eye to take pictures. Specific functional characteristics: (1) Definition: CCD (Change Coupled Device) is a semiconductor device that can convert optical images into digital signals. 3CCD, as the name suggests, is a camera using 3 CCDs. (2) Composition and function: CCD is composed of one or more cameras and lenses. This system is composed of two cameras and lenses, which are used to photograph printed products to be tested. The 3CCD uses three CCDs to convert the red, green, and blue signals. The captured image is more natural than a single-chip CCD in terms of color reproduction, and the brightness and definition are better than that of a single-chip CCD. (3) Classifica...

Abstract

The invention relates to an online quality detection system for printed matter. The system consists of a 3CCD camera, an LED-array light source, an MV-600 high-speed/high-accuracy industrial image acquisition card and a computer host with a PC (Personal Computer) and image processing software. The online quality detection system is applied to online quality detection in online intaglio printing and online flexography of roll paper in cigarette packet production enterprises, and batches of defective products with shape defects and color defects can be avoided in cigarette packet printed matter. Moreover, hardware is not in contact with the printed matter during online detection, so that the quality of the printed matter is not lowered. By the online quality detection system, the problems of lagging of detection time and insufficient principle basis of a conventional subjective visual observation method, density detection method and chromaticity detection method are solved, the production efficiency is increased, material waste is reduced, and the demand of labor force is lowered.

Description

technical field [0001] The invention relates to the field of quality detection of printed matter, in particular to an online quality detection system of printed matter. Background technique [0002] With the rapid development of the economy, people's living standards continue to improve, and their pursuit of quality has gradually improved. Reflected on the cigarette label, it is reflected in the diversification of cigarette pack carton technology, high-end product forms and strict quality requirements. The printing process of cigarette labels is becoming more and more complex, and the quality and fineness requirements are getting higher and higher. The limitations of printing enterprises in quality control need to be resolved urgently. [0003] Traditional detection methods are easily affected by observers' experience, psychological and physiological factors, and have poor stability and accuracy. The detection time lag is large, and there are often tens of thousands of de...
