When Good Scanning Goes Bad: A Case for Enabling Statistical Process Control in Image Digitizing Workflows
The benefits of SPC in industry are recognizable in terms of quality, efficiency, and economy. The same can occur with digital imaging in the cultural heritage community. Any SPC program naturally involves monitoring selected output parameters. The short list could be sampling rate (dpi), resolution, noise, and tonal/color fidelity. By way of a suitable target artifact and analysis software, each of these variables can be periodically measured and their values compared to pre-established numerical aims and error bounds. Corrective action is taken when trends approach or exceed these bounds. This paper describes efforts at the Library of Congress to introduce SPC practices into imaging workflows by supporting the development of unique hardware and software tools that provide ISO standardized imaging performance measurements.
In addition to advocating the incorporation of genuine SPC practices into the imaging workflows of cultural heritage institutions, we also present some encouraging progress on enabling ISO imaging performance compliant tools to accomplish this in a workflow and archiving friendly fashion. Results exercising these tools are shared, and future approaches are presented. Because of its fundamental importance, the image capture stage is the focus of this paper. However, the principles involved apply equally to display, printing, and metadata generation.

The IS&T (digital) Archiving Conference offers a unique opportunity for imaging scientists and those working in the cultural heritage community (curators, archivists, librarians, photographers etc) from around the world to come together to discuss the most pressing issues related to the digital preservation and stewardship of hardcopy, and other cultural heritage documents and objects. Authors come from museums, archives, libraries, government institutions, industry and academia. Cutting edge topics related to multispectral and 3D imaging, as well as best practices for workflow, sharing, standards, and asset/collection management and dissemination are explored in papers presented at this annual, international event.
