ISO/IEC 19799:2007定义了测量客观打印质量属性的方法和过程，以评估反射模式下打印页面上的光泽不均匀性，并在适用时提供了将客观结果与主观响应（如果合适）相关联的变换。ISO/IEC 19799:2007中包含的光泽度均匀性属性是差异光泽度、页面内的光泽度均匀性和运行内的光泽度一致性。 ISO/IEC 19799:2007规定 表示反射打印上的打印质量的光泽均匀性属性的定义， 一组打印文件，用于创建用于光泽均匀性测量的打印页面， 光泽均匀性测试和所得数据分析的程序， 一种用于评估和分级这些测量值并导出光泽均匀性评估的方法， 在制造商提供给消费者的文件中描述打印和复印系统光泽均匀性的适当方法。 可以通过打印机或复印机（模拟和数字）创建用于测量的反射打印。 ISO/IEC 19799:2007仅适用于基于电子照相的印刷品。它不涉及在传输模式下测量打印页面的光泽属性。

ISO/IEC 19799:2007 defines methods and processes for measuring objective print quality attributes for the assessment of gloss non-uniformity on printed pages in reflection mode, and provides transforms, when applicable, that relate the objective results to subjective responses if appropriate. The gloss uniformity attributes included in ISO/IEC 19799:2007 are differential gloss, gloss uniformity within a page, and gloss consistency within a run. ISO/IEC 19799:2007 provides

• a definition of gloss uniformity attributes representative of the print quality on reflection prints,
• a set of print files for the creation of printed pages for gloss uniformity measurement,
• a procedure for gloss uniformity testing and the analysis of the resulting data,
• a method for evaluating and grading these measurements and deriving an assessment of gloss uniformity,
• the appropriate method of describing the gloss uniformity of printing and copying systems in documentation supplied to the consumer by the manufacturer.

The reflection prints that are to be used for measurement can be created via printers or copiers (analog and digital). ISO/IEC 19799:2007 is applicable only to electro-photographic based prints. It does not address the measurement of gloss attributes of printed pages in transmission mode.
