Common-view observer for contrasting printing quality of cigarette labels and realization method of observer

Abstract

The invention discloses a common-view observer for contrasting the printing quality of cigarette labels. The observer comprises a pixel acquisition system, a prism conduction system, a projection display system and more than two sets of observation systems, wherein the pixel acquisition system is connected with the prism conduction system; standard cigarette label image information and cigarette label image information to be observed are vertically projected on the projection display system below the prism conduction system through the prism conduction system; and the observation systems are distributed above the projection display system in a circumferential array mode. The invention also discloses a realization method of the common-view observer for contrasting the printing quality of the cigarette labels. By the observer and the method, the problems of incapabilities of observing two contrast samples synchronously in real time and observing all contrast samples through multiple persons, low observation efficiency, inconvenience in operation and the like in the prior art are solved. The invention has the characteristics that: the observer has a simple structure, low constructioncost and high observation efficiency and is easy to operate, cigarette label printing quality information can be accurately known, the printing quality of the cigarette labels can be observed by multiple persons simultaneously, and the like.

Description

technical field [0001] The invention relates to the technical field of cigarette label printing quality detection, in particular to a common-view type cigarette label printing quality comparison observer and an implementation method thereof. Background technique [0002] The evaluation of the printing quality of cigarette labels is achieved by comparing with standard cigarette labels. Some obvious printing defects such as chromatic aberration, registration, and dirty spots can be directly observed by human eyes, but quality problems caused by micro-deviations such as dot size, dot shape, dot count, and slight deviations in registration require the use of pixel amplification devices ( Such as a magnifying glass above 40X) to complete. When observing, the pixels at the same position of the standard cigarette label and the cigarette label to be tested are enlarged respectively, and then compared and analyzed to grasp the printing quality of the cigarette label. However, there...

AI Technical Summary

Problems solved by technology

[0003] (1) It is impossible to observe the two comparison samples in real time and synchronously, which is easy to cause an "impressionist" comparison

When observing, because it is observed on one cigarette label first, an impression is formed in the mind, and then observed at the corresponding position of another cigarette label and compared with the impression, there are a lot of artificial perceptual factors, and it is not easy to accurately grasp the microcosmic printing. quality information;

[0004] (2) Since the observation process needs to be carried out in two steps, the observation efficiency is low, and it is difficult to grasp the same position of the two cigarette marks

When there are many observation points, the observation work will become quite cumbersome and extremely inconvenient to operate;

[0005] (3) There is only one eyepiece, which cannot enable multiple people to observe at the same time, and cannot meet the real-time sharing of team information

When it is used for multi-person observation, it can only be carried out in turn. Everyone has different grasps of information such as color difference and overprinting, so the impressions formed are different, which is not conducive to the communication of information in the team
