Precision test charts for more accurate results
In general, the image quality of scanners and cameras is tested using charts that are a degree better than the expected test result of the device under test.
The TE240, which measures the dynamic range according to ISO 21550, is available as a transparent and reflective chart. In reflection, the achievable contrast is limited to about 2.4 densities. In transmission, the user can select between 4.0 and 6.0 densities. The IT8 color target (TE258) is the standard target for color profiling, and we provide it in a reflective and a transmissive version with a broad color gamut.
The TE250 (transparent test chart) is used for visual resolution measurement for scanners, according to ISO 16067, and is done traditionally with the slanted edge target QA-62 (reflective)
The Starter Kit - Scanner consists of:
- TE250 - USAF target sizes 145x155mm (reflective) and D35 mm (transparent)
- TE240 - ISO 21550 dynamic range chart sizes 150x100mm (reflective, possible density 2.0) and D35 mm (transparent, possible density 4.0 or 6.0)
- TE258 - IT8 scanner characterization chart sizes 127x178mm (reflective) and D35 mm (transparent)
- QA-62 - slanted edge target / scanner SFR & OECF size 95.25x76.2 mm (reflective only)
