No Wasted Efforts (Web Inspection)

AVT President Lance Shumaker expands on these technologies, specifying sampling systems are much better for detecting small process defects before they become print waste. "This equipment is typically much more sensitive than 100 percent inspection systems," says Shumaker. "It allows printers to identify changes on the press which may affect both quality and productivity." Shumaker explains 100 percent inspection systems will detect most larger random defects, which represent only about five percent of all printing defects. The biggest difference between sampling and 100 percent systems lies in the ability to identify a printing process problem versus a random print defect.
