IPC: G01J3/46
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a method which shortens the time needed confirm a color from toning request time to toning end time. SOLUTION: A 'confirmed-side' spectral colorimeter reads a color to be confirmed and computes spectral reflectance at 16 or 32 discrete points, for example, in the wavelength range (380 to 780 nm) of visible lights (step S101).
