Inspection System for Printing Quality Control

Printing Quality Inspection

With the improvement of the living environment and health awareness, there are more and more requirements for packaging materials and printing quality. Small printing defects, result in huge economic losses to printing manufacturer, and further to loose the trust from customers. Because of the lower market price of printed matter, factory has to focus on using raw materials economically. Besides, printing manufacturers also face huge pressures such as decreasing production quantity, increasing product varieties and shortened delivery cycle. Not only to improve work efficiency and reduce costs, but also to satisfy customers' requirements for multicolor, high difficulty and high quality printing. High precision automatic online-inspection system are used to detect defects on printed matter in printing process.

Tension Control for Film Winding

Film Tension Control

Film tension control in slitting or rewinding process means the ability to permanently control the tension of the film passing through the equipment. This tension control must remain valid for any operating speed no matter acceleration or deceleration, make sure without damage to film even in emergency braking. The stability of tension control is directly related to the product qulity. If the tension is insufficient, the film will drift in the running process, and the film coils become wrinkle. If the tension is excessive, the thin film is easily broken, result in lots of broken ends on coils after cutting and rewinding process. This article deeply analyses the problem of tension control for film winding.
