Details for Sample per Inch (Scanning Resolution)
Introduction : Measures how many samples a scanner takes per linear inch. Determines the fidelity of digitized images, especially for archival or forensic work.
History & Origin : Introduced with drum scanners in the 1970s. Later adopted for flatbed scanners, with high-end models reaching 4800+ SPI for film scanning.
Current Use : Essential in document digitization (300 SPI for text, 600+ SPI for photos), film scanning (2400+ SPI for 35mm negatives), and forensic image analysis.
Details for Dot per Meter (Linear Dot Density)
Introduction : Measures the number of dots printed or displayed per linear meter. A fundamental metric resolution unit, often used in large-format printing and industrial imaging where meter-scale precision is required.
History & Origin : Derived from the metric system's need for standardized resolution units. Gained relevance with the rise of wide-format printers and digital textile printing in the late 20th century.
Current Use : Used in wide-format printing (e.g., billboards, fabric printing), where resolutions are calculated per meter rather than per inch for consistency with metric workflows.
