When digitizing journals and books, we use different scanners based on the quality and size of the volumes. The digitization of particularly valuable individual copies happens with the so called robotic scanner. In order to avoid any damages of the volumes, the robotic scanner allows to open the book for only 90 degrees. Two high resolution cameras ensure producing high-quality images at up to 400 DPI in TIFF or JPG format. The clamping prism is very gentle, the paging is typically done in semiautomatic mode.
We digitize large sized documents (larger than A3) with a book scanner. The size of the page can be even up to A2. Scanning illumination and the scanning itself result a very good picture quality. With our book scanner it is not necessary to open the volumes up to 180 degrees that ensures a gentle handling.
