On the question of effective resolution and color verification in the process of digitization

Ladislav Bezděk

The article explains the issues of conflict between the "optical resolution" of scanners that manufacturers often cite in the technical specifications, and the effective resolution, i.e. the actual values achieved by specific devices in practice and which can be substantially lower than the optical resolution declared by the manufacturer in some devices. The second part points out the abysmal differences in quality between different brands of scanners, even for instruments whose prices range from the hundreds of thousands or millions of Czech crowns. Specifically, it addresses the distortion of color rendering, image distortions, streaking, blurring, and other defects.

Keywords: scanners; optical resolution; effective resolution; scan quality; scanning defects
