SilverFast Resolution Target in Detail

Based on the USAF-1951 standard, LaserSoft Imaging developed the SilverFast Resolution Target to make the actually usable resolution of a scanner measurable. This is a transparent scan original, which is suitable for either flatbed or film scanners.* 

The structure and elements of the Resolution Target are defined to an American military standard. On the target there are smaller and smaller elements, each consisting of black bars of precisely defined width and spacing. These individual elements are numbered and organized into groups on the Resolution Target. The smallest of these elements for which the scanner can just differentiate between two bars, for which the intervening space is thus barely still detectable, can be indicative of the usable resolution of the scanner. The Resolution Target can also be used to make statements about the sharpness at different resolutions, in order to find the optimum resolution for scanning and to differentiate the sharpness at different points in the scanned area of a flatbed scanner.
