SPECTRAL REFLECTANCE MEASURING SHEET, METHOD OF MEASURING SPECTRAL REFLECTANCE, AND PROGRAM FOR CONTROLLING SPECTRAL REFLECTANCE MEASUREMENT

摘要

PROBLEM TO BE SOLVED: To prevent a spectral reflectance measuring sheet from being measured in a wrong order or being set at a wrong position to be measured.;SOLUTION: In the spectral reflectance measuring sheet 101, two position determining marks 104-1 to 104-2 and order determining marks 105-1-105-6 indicating the order of the sheet to be measured are printed, in addition to a large number of color patches 102 outputted by a printer whose color reproductivity is to be measured, at prescribed positions. The spectral reflectances at the positions with the marks 104-1 and 104-2 are measured when the sheet is set in a measuring device, and when the two marks are normally detected, it is determined that the sheet is set at a proper position. The marks 105-1-105-6 are provided in number equal to the order of processes of the sheet, and an operator is informed of the order of processes of the sheet by the marks. Further, the spectral reflectance of the positions of the marks 105-1-105-6 are measured to be used for confirming whether the sheet is set in the proper order or not.;COPYRIGHT: (C)2002,JPO
