In 2007 the federal government agencies began a collaborative effort to articulate “common sustainable set of technical guidelines, methods, and practices for digitized and born digital historical, archival and cultural content.” This effort led to the creation of FADGI (Federal Agencies Digital Guidelines Initiative) standards—a four-star ranking system for image quality. Higher star ratings relate to better and more consistent image quality, but can increase overall production costs.
If you are planning to digitize a collection of records you will probably be asking yourself if FADGI compliance is a true requirement. If the collection will stay local or be uploaded to your digital content management solution for the ease of search and retrieval, you may never have to worry about FADGI compliance.
If the collection has any chance of being transferred to the National Archives or the Library of Congress, then yes, it would be in your best interest to have a solution in place that meets the respective FADGI requirements.

Should only be considered informational, in that images are not of a sufficient quality to be useful for optical character recognition or other information processing techniques. One-star imaging is appropriate for applications where the intent is to provide a reference to locate the original, or the intent is textual only with no repurposing of the content.
Appropriate where there is no reasonable need or expectation of achieving three or four star performance. These images will have informational value only, and may or may not be suitable for Optical Character Recognition (OCR).
A very good professional image capable of serving almost all use cases. This includes being suitable for OCR as well as for reprint on the best commercially available printers.
Images created to a four-star level represent the state-of-the-art in image capture and are suitable for almost any use.
