Inline Versus Offline Inspection

Ease of use is also important. “Operators have a lot of work to do to get a printer functioning correctly to get high-quality output,” says Lydell. “The last thing you want to do is have a complicated system for them to master and monitor. Or even worse, have two systems on the press that are checking for print quality.” He asserts that this can happen when one system is checking for blemishes and another system is checking bar codes to ISO standards, or there are other variable images needing validation. “The converter should insist on a system that can do both functions at the same time so there is less work for the operator,” he adds.
