Eye On Inspection

• Gal Shamri, VP marketing, Advanced Vision Technology: First, we have to differentiate between a “viewer” and an automatic inspection and defect detection solution. While a simple viewer only views a captured image on a monitor, an automatic inspection system automatically analyzes the image, and detects print defects and quality variations along the production run. This enables operators to perform corrective activities before producing waste and to remove defective material before shipment. Equipped with an area camera, process control systems detect process defects at the earliest stage, enabling the printer to avoid defects before running waste, hence reducing waste material cost. One of the main advantages of the process control platform is its ability to host a variety of added-value modules such as in-line color measurement, register control, pressure control, bar code verification solution, and many others. One hundred percent quality assurance solutions such as the AVT PrintVision/Apollo are typically installed on post-press machines and are based on Line-CCD camera technology. Quality assurance systems detect all defects appearing on the entire repeat 100 percent of the time, assuring waste defects are detected and removed before shipment.
