The importance of computer full inspection combined with manual quality inspection in printing production

Our company's thermal transfer printing production mainly uses gravure printing technology. Due to factors such as operating technology and equipment accuracy, gravure printing technology usually causes registration errors, scraper lines, plate blocking, anti-sticking and other printing defects. Although during the production process, we have made preliminary inspections on the film's tension, adhesion, color difference, registration, etc., the speed of gravure printing is very fast. When the captain is adjusting the machine, the defective film has already been It is involved in the finished product, so we must conduct a full inspection of the film later.

The company, including other companies currently, generally uses manual inspection. Manual inspection is mainly done through human eyes. Even if our employees have been trained and have good eyesight to detect defective products, over time, their eyes will If fatigue occurs, it will inevitably lead to missed inspections, causing defective films to flow into the hands of customers. For example, some films with small-sized patterns only cost a few cents. If customers print on plastic products, it will cost several yuan or even several dollars. A loss of ten yuan, so we have been working hard to solve the problem of missed inspections.

At present, the company has used large-volume quality inspection machines, and all flower films produced are fully inspected before leaving the factory. Quality inspection machine inspection is based on computer positioning and scanning inspection. Compared with manual inspection, it is more accurate and comprehensive, and solves the problem of missed inspection to the greatest extent.
