In the application of this standard equivalent to the direct use of filters and techniques to measure the density of states limit the bandwidth of the measuring instruments, as well as spectral measurements and calculate the density of states of the measuring instruments. This standard does not apply to an instrument measuring continuous tone originals.

" For ease of use, the standard of ISO 14981.2000 made the following editorial changes. ISO 15790 printing and photography reflection and transmission cytometry certified reference material application documents and routine package Including determination of combined standard unreliability3 Terms and DefinitionsThe following terms and definitions apply to this standard. Note. For a variety of value, given the definition of its preferred units together. By definition, "dimensionless" is a unit of volume. 3.1 No hue of colors, such as. black and gray. For the transmission object is also used to describe the colorless or neutral colors. [CIE17.4845-2-26] [6] Note. In the practice of printing, using black ink monochrome or gray balance satisfying the three-color ink to produce a non-color. 3.2 Under certain conditions, through a set of operations, establish a relationship by the measuring instrument or measuring system, a plurality of instructions in response to the magnitude of the standard value, Relationship or the value of the standard value of a material measure or reference material provided between [5]. NOTE. In contrast with the common misconception, not by adjusting the calibration and measurement system to produce a credible process of correct data, but from credible measurement data Guarantee.
