Significance and Use | ||||||||||||||
This practice enables image quality evaluation on samples generated by various imaging systems. It can be used to conduct investigations, including image reflectance, sharpness, voids, character width, and degradation of materials. The test instruments can be used for research and development projects as well as for manufacturing control. |

1. Scope | ||||||||||||||
1.1 This practice covers the use of the reflectance-type optical character testers with a 0.008-in. (0.203-mm) aperture as test instruments for measuring image quality. 1.2 Although other systems may be available, this practice covers two of the most commonly used instruments; the Clearwave 082 Optical Character Tester and the Macbeth Print Contrast Meter. 1.3 These instruments also have the capability of predicting machine readability of documents. This practice does not address this capability. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 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. |
