6、s and operated under a controlled environment for alength of time sufficient for stable performance.A color testimage is created using a program for the printer or a standardcolor chart for copiers.A colorimeter is used to measure theprinter or copier output by determining color difference valueswhi
7、ch correlate to visual color assessment.4.Significance and Use4.1 This test method is used to evaluate the color outputcapability of color printer/plotters or copiers.The color copy,print,or plot is measured such that the results can be correlatedto human color vision.4.2 This test method can be use
8、d to make machine-to-machine comparisons.It can be used to compare color printeror copier processes(ink jet,thermal transfer,etc.).4.3 This test method can be used to compare imagingsupplies such as toner,ink,thermal transfer ribbons,and paper.5.Interference5.1 Any changes in the color of the paper,
9、surface proper-ties,or brighteners may affect the color measurement.5.2 The measured color may be affected by the location onthe paper due to uneven toning or positional variations in theimaging process.5.3 If the print samples to be tested are not completelyopaque,the color measurements will be aff
10、ected by the backingmaterial.5.4 The preferred colorimeter geometry excludes gloss fromthe measurements.Any differences in sample gloss will not bemeasured by the colorimeter.6.Apparatus6.1 Colorimeter,capable of measuring human vision colorparameters.The colorimeter shall be capable of measuring in
