3.11 Image Format

The majority of documents imaged only require black and white. On a less frequent basis, we may need color images. The following are our standards:

1.       Black and White images should be 300 DPI, Group IV TIFF;

2.       Single page TIFF images;

3.       Color images should be discussed on a per image or per document type basis;

Please use the following guidelines, borrowed from Adobe’s recommendations when scanning images:

·         Choose grayscale for variable contrast pages in the scanning software.

·         Increase brightness and contrast by 10% for text on colored paper, or filter out the background if your scanner includes that option in the scanning software.

·         Adjust manual brightness control on the scanner if your scanner includes that option (for example, a knob).

·         Use 16-bit color or less; 24-bit color images take considerably more system resources in the scanning software.

·         Don't use any dithering or half toning options in the scanning software.

Oversized Documents

Every oversized document should result in two pages in the database. The first page shows a legend, Bates or any other identifying marks. The second page should be a full-scale image.

Should the document be a five-foot color map, a full-sized .JPG may be required. In this case, an accompanying first page black and white image of just the map legend is still required.
