Unlike standard camera technology, the new Discovery MaxScan from Lake Image is said to provide a true 600dpi resolution for print inspection applications at web or sheet widths of 309mm, 619mm or 929mm.
According to Lake, this can match or exceed the resolution of most print engines, enabling a variety of inspection functions including missing or blocked jets using the full Discovery MultiScan toolset. MaxScan also provides full colour images with excellent colour representation and repeatability, the company promises.
The MaxScan's Linear Contact Scanner has a working distance of just 12mm. With a maximum headroom requirement of less than 130mm, the Discovery MaxScan can be easily integrated within the transport system of a press - without the need for additional rollers, redesigned web paths, large working distances or complex optical assemblies typical with standard camera inspection technologies.
A major advantage claimed is its ability to provide consistent and reflection-free images of holograms and foils. This is a significant challenge for camera based inspection technology, where each hologram in a row or lane can appear different within the inspection image based on its location relative to the camera position.
