    影響印刷機器視覺缺陷檢測的因素

    來源:http://www.mbtshoesclearanceinc.com/   發布時間:2020-12-07
    近年來,“智能印刷”“云印刷”“智慧印刷”“印刷工業4.0”“印刷工業互聯網”等詞匯充斥于各種媒體,讓印刷人既為美好未來而興奮,又為不知如何下手而迷茫。今天濟南印刷廠來給大家介紹一下影響印刷機器視覺缺陷檢測的因素。
    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、設備波動造成的紙張蛇形跑動問題
    1. Paper snake running problem caused by equipment fluctuation
    在印刷過程中,隨著張力和速度的波動,紙張在前進過程中會產生蛇形跑動現象,表現在運動方向的不同程度的拉伸,以及寬度方向的不同程度的偏移,給圖像的采集和對比造成困難。
    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、檢測后的處理問題
    2. Handling problems after testing
    檢測只是質量管理的手段,檢測的目的是為了指導生產,及時杜絕連續廢品的發生;同時也應當為成品出廠提供判斷依據。目前在這方面國內外多數在線檢測系統均未提出較好的方案。
    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、印刷材質問題
    3. Printing material problems
    印刷材質除了常見的白卡紙、銅版紙外,還存在很大比例的轉移紙(包括金銀卡紙、鐳射紙),紙上除了印刷外,還有素面燙金、全息定位燙金等印后工藝,其強反射特性給普通照明條件下的檢測帶來難度;而且壓凸圖案由于低色差特性也給檢測帶來困難。
    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.
    以上就是影響印刷機器視覺缺陷檢測的因素,另外印刷機是絕大多數印刷企業的資產重心,印刷效率決定了大部分企業的效益。目前,在印刷環節,還存在大量時間浪費在調整套準、調整顏色、擦橡皮布、洗印版上的情況。
    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.
