Testbed and Methods
We will follow our original methodology of testing scanners with the Scanjet 8200, too. But this time there will be one more section concerned with the scanner’s modulation transfer function (MTF). We can do that with the help of an Applied Image QA-69-P-RM test target. So, our tests consist of the following steps:
- Scanning speed: we will determine the time it takes to digitize a few standard-size originals;
- Noise tolerance: we will calculate the digital noise coefficients in the digitized images to evaluate the tolerance of the scanner’s electronics to interference;
- Resolution: we’ll check out the scanner’s modulation transfer function;
- Color reproduction: we’ll find the gamut range of the scanner with reflective originals and will evaluate the quality of the scans visually;
The computer the scanner was attached to had the following configuration:
- Intel Pentium 4 3.00GHz CPU;
- 1GB DDR SDRAM;
- Intel Bonanza D875PBZ mainboard;
- ATI RADEON 7000 graphics card;
- IBM DeskStar DTLA307015 HDD;
- Samsung SyncMaster 757 NF monitor;
- Microsoft Windows XP Professional with Service Pack 1.
The configuration of the testbed remains the same from test to test, so I (and you) can compare the results to those I got in my earlier reviews.
