Scope

This document specifies the requirements and recommendations for digital test files, printer settings, and printing procedures used to generate print targets, as well as standards and norms for image stability testing methods for reflective color photographic images. In addition, this document also stipulates the measurement procedures for test color patches and how to calculate changes in color attributes during a given image stability test. The definition of statistical procedures for data simplification and the conversion of these changes into psychophysical endpoint levels are beyond the scope of this document. However, the results obtained using the methods defined in this document can provide appropriate statistical evaluations and endpoint systems for print material lifespan specifications defined in other documents.
