Can the highest effective resolution only be achieved with the maximum resolution of 7200 dpi?
This question could also be expressed by this way: is the adjustment of 3600 dpi sufficient in order to achieve the highest resolution in the scan? The background is as follows: according to the manufacturer, the RPS 7200 has a mega resolution of 7200 dpi. This means double as its previous model, the RPS 3600. But this superlative value – as already expected – is hardly achieved in reality. The actual effective resolution that is achievable with the RPS 7200 can be determined with the help of an USAF-1951-test charts. In our Test Report, we have measured for the RPS 7200 Professional an effective resolution of 3.800 dpi. In order to answer this question, we have made again some resolution tests with another device. The have scanned the test chart with bar elements of different sizes, once with 7200 dpi and once with 3600 dpi. On the screen, the smallest distinguishable bar elements of both scans are analyzed. One bar element consists on three horizontal and three vertical bars, as the
