影响印刷机器视觉缺陷检测的因素

来源:http://www.xinfengyinshua.cn/   发布时间:2020-12-07
近年来,“智能印刷”“云印刷”“智慧印刷”“印刷工业4.0”“印刷工业互联网”等词汇充斥于各种媒体,让印刷人既为美好未来而兴奋,又为不知如何下手而迷茫。今天济南印刷厂来给大家介绍一下影响印刷机器视觉缺陷检测的因素。
In recent years, words such as "intelligent printing", "cloud printing", "intelligent printing", "printing industry 4.0" and "printing industry Internet" have flooded various media, making printers excited about the bright future and confused about how to start. Today, Jinan printing factory will introduce the factors that affect the visual defect detection of printing machines.
1、设备波动造成的纸张蛇形跑动问题
1. Paper snake running problem caused by equipment fluctuation
在印刷过程中,随着张力和速度的波动,纸张在前进过程中会产生蛇形跑动现象,表现在运动方向的不同程度的拉伸,以及宽度方向的不同程度的偏移,给图像的采集和对比造成困难。
In the printing process, with the fluctuation of tension and speed, the paper will produce snake running phenomenon in the process of moving forward, which is manifested in different degrees of stretching in the movement direction and different degrees of offset in the width direction, which makes it difficult to collect and compare images.

2、检测后的处理问题
2. Handling problems after testing
检测只是质量管理的手段,检测的目的是为了指导生产,及时杜绝连续废品的发生;同时也应当为成品出厂提供判断依据。目前在这方面国内外多数在线检测系统均未提出较好的方案。
Testing is only a means of quality management, the purpose of testing is to guide production, timely eliminate the occurrence of continuous waste; at the same time, it should also provide judgment basis for finished products. At present, most of the online detection systems at home and abroad have not put forward a better scheme.
3、印刷材质问题
3. Printing material problems
印刷材质除了常见的白卡纸、铜版纸外,还存在很大比例的转移纸(包括金银卡纸、镭射纸),纸上除了印刷外,还有素面烫金、全息定位烫金等印后工艺,其强反射特性给普通照明条件下的检测带来难度;而且压凸图案由于低色差特性也给检测带来困难。
In addition to common white cardboard and coated paper, there are also a large proportion of transfer paper (including gold and silver cardboard, laser paper). In addition to printing on paper, there are post printing processes such as plain gilding, holographic positioning bronzing, etc., whose strong reflection characteristics make it difficult to test under ordinary lighting conditions; moreover, the low chromatic aberration of embossed patterns also makes detection difficult.
以上就是影响印刷机器视觉缺陷检测的因素,另外印刷机是绝大多数印刷企业的资产重心,印刷效率决定了大部分企业的效益。目前,在印刷环节,还存在大量时间浪费在调整套准、调整颜色、擦橡皮布、洗印版上的情况。
These are the factors that affect the visual defect detection of printing machine. In addition, printing machine is the asset center of most printing enterprises, and printing efficiency determines the benefits of most enterprises. At present, in the printing process, there are still a lot of time wasted in adjusting registration, adjusting color, wiping blanket, washing plate.
