Inspection principle

As a main form of product packaging, flexible packaging has the advantages of beautiful appearance, cleanliness, low cost, and convenient use. It is widely used as the outer packaging of food, medicine, daily necessities and other products. Flexible packaging materials are diverse and require high printing accuracy as well as high detection speed. The domestic flexible packaging printing process is mainly gravure, with post-printing processing such as compounding, slitting, and bag making. A variety of printing defects may occur during the printing process, such as dirty version, pasted characters, color difference, inaccurate overprinting, dirty spots, mosquitoes, foreign objects, missing printing, flying ink, knife silk, dragging ink and other defects.

Due to the importance of flexible packaging and its unique high-speed printing characteristics, and with the improvement of living standards, higher requirements are placed on the printing quality of flexible packaging. How to control the quality of flexible packaging printed products has always been a problem that plagues all flexible packaging printing companies. . At present, the quality control of flexible packaging printing mainly includes process control and result control. In the gravure production process, both process control and result control are indispensable. They are not only the key points for quality improvement in printing enterprises, but also the basis for formulating quality improvement measures.

Inspection details

In-print control is to standardize, standardize and digitize every process link of gravure, and adopt certain quality standards to establish a quality control prevention mechanism. The main concern is to prevent continual charges or mass waste and prevent wastage of materials. The defects that may lead to a large amount of waste are overprinting, knife wire, color difference, and a large amount of flying ink. At present, almost all gravure printing machines are equipped with a computer overprint control system, and at the same time, with the help of still pictures and strobe lights, defects such as cutting wires, flying ink, trailing, burrs, missing printing, color bites, foreign objects, and plate blocking are manually observed. Post-press control is the inspection and control of the overall quality of the printed product after printing, including rewinding inspection, slitting inspection, and post-bag inspection.

The main method at present is to observe the defects manually by means of a strobe light. However, due to the limited control of tension fluctuations by the gravure printing machine, the computer overprint control system cannot fully guarantee the complete stability of overprinting during the printing process, while still images and strobe lights are typical sampling modes, and manual observation is more subjective and negligent. risk. Through our market research and customer feedback, flexible packaging printing companies mainly need to detect typical defects such as overprinting, color cast, dirty spots, knife threads, mosquitoes, and foreign objects in the printing process. The inspection requirements are roughly as follows. At the same time, we have noticed that the quality requirements of flexible packaging printing are getting higher and higher.
