Drum Scanning l Scanning ImageA type of scanner used to capture the highest resolution from an image. Photographs and transparencies are taped, clamped or fitted into a clear cylinder (drum) that is spun at speeds exceeding 1,000 RPM during the scanning operation. A light source that focuses on one pixel is beamed onto the drum and moves down the drum a line at a time. For transparencies, light is directed from the center of the cylinder. For opaque items, a reflective light source is used. Mirrors filter out the RGB values and send them to the drum scanner's photomultiplier tube (PMT), which is more sensitive than the CCDs used in flatbed and sheet-fed scanners and can produce resolutions exceeding 10,000 dpi. If one PMT is used, three passes across the image are required. When three PMTs are used, a faster single-pass scan is performed. KS Designers understand color and how to reproduce it properly. Our high quality scans are achieved using our DS-Screen high resolution drum scanner and its advanced AI (artificial intelligence). I have my own drum scanner, and I'm able to offer drum scanning services to other designers as well. This scanner can be used to scan art/images/transparencies used to print the highest quality magazine cover to the largest billboard sign. All scans are professionally cleaned and oil mounted, reducing the amount of inperfections, (such as scratches) that are on your original media. KS Designers scan from your original Transparencies since it is the finest grain film, however we do work from 35mm slides, 35mm negatives (much grainier than slides), reflective photos (also grainy).
