4.1 This test method can be used for the evaluation of the electrophotographic printer output image quality, aesthetic appearance, visual impression of blackness and the ability to distinguish information from the background.

4.2 This test method can be used for the evaluation of new and remanufactured toner cartridges and their respective components used in an electrophotographic printing process.

4.3 This test method can be used to evaluate printer output image density and background under specified environmental conditions.

4.4 This test method is suitable for research and development and quality acceptance evaluations.

1.1 This test method describes the procedure for measuring the monochrome diffuse reflection print density and background for large areas on printed pages from electrophotographic printers. It describes the test target and calculations for evaluating the print density and background.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
