Two-Dimensional Manuscripts or Artifacts
Type of Document
This includes all original documents or artifacts which require faithful reproduction of the colour and/or texture of the material and the information it contains.
- Older manuscript on which you want to show signs of aging and/or deterioration
- Annotated document
- Scale drawing
- Work on paper
- Birthday card/postcard
- Keep a border around the document to allow reframing of the document as well as later modifications (e.g., removing the scale and document number).
- Batch digitization enhances productivity, but does not offer optimal rendering of individual images.
- For documents larger than the surface of the digital scanner use the instructions for normal-sized artifact photography.
- For documents with several pages, consider producing a PDF document from the originals, or from black-and-white copies.
- 300 ppi, with a minimum of 3,000 pixels for the longest measurement (8 x 10, or 1:1 for formats larger than 8 x 10).
- Refer to the general guidelines to calculate the number of ppi required for a given dimension.
Note that it is the original document which measures 8 x 10, not the final digital file.
- Digitize in reflective mode.
- Select 48-bit mode on the scanner to capture the maximum number of colours. If this option is not available, 24-bit mode is acceptable.
- For reference purposes, digitize a colour scale (Kodak Q-14 or Q-60) before each digitization session.
- Use a grey background.
- Digitize the document with a grey or colour scale and, depending on available space, always place it in the same position (ideally lower left).
- Colour-balance each image as indicated in the general guidelines. If there is no greyscale reference, balance the levels of white in the brightest zone (D-Max), then balance the black in the darkest zone (D-Min).
- Enlarge the frame by one inch at the bottom, and type the document number in black at the lower right (font: Arial, 40 pts.).
- Flatten the image (i.e., flatten layers).
- Convert in Adobe RGB 1998 profile, 8 bits per channel (total 24 bits).
- Save the image as an uncompressed TIFF, named to standards established by the Corporation's Photo Archives.
- Produce a JPEG version as described in the general guidelines.
