With up to 4,000 dpi optical resolution, the ArtixScan 4000tf can enlarge 35mm scans to full A3 or tabloid-size scans with no degradation to output quality. Scans are fast and take under one minute. And with a 4.3 Maximum Optical Density plus Multiple Sampling, the 4000tf captures exceptional shadow and highlight detail. For increased productivity, two auto-advancing batch scanning cartridges are provided, and an optional APS film roll cartridge allows automated batch scanning of up to 40 images per loading.
