Digitisation of Old Rare Maps in Oxford UK
Archiving and Scanning Digitisation at Oxford Duplication Centre
Heritage maps are fragile and can easily become damaged with age deterioration. The first process in capturing historical maps is to make a HQ TIFF detailed image of the map which can be kept digitally.
HOW WE CAN SUPPORT YOU WITH YOUR HISTORICAL PROJECTS
Documents are digitised to the highest possible quality (to avoid redigitisation) and digital copies are preserved using long term digital storage with backups. For online presentation a derived copy (a down-sampled lower quality version) is created from the master image.
The primary reasons for digitising maps are to allow easy access to documents and protect the physical originals and minimize handling of them. Original documents are fragile and likely to be lost in the near future. At Oxford Duplication we scan a perfect copy as possible. Typically 600 dpi or better 1200 dpi, with lighting and colour calibration (ICC profile), lossless compression as a standard.
FUTURE PROOFING YOUR FUTURE ARCHIVES
Formats for storing the digitised masters of historical documents and maps: Uncompressed TIFF JPEG2000 part 1 (lossless and lossy), JPEG, PNG, TIFF. For text documents like newspapers or books, we use formats to include PDF-A.
PREPARATION OF MASTER DIGITAL FILES
We are competitive in price but realistic with the work that may be required. The condition of the orders are taken into consideration. If the orders are clean and requires less attention then this will keep the prices down. If the paper is damaged or needing attention ie cleaning and preparation work then this slows the process down and the price will be reflective.
