PROBLEM TO BE SOLVED: To provide a colorimetry system being high in cost performance. SOLUTION: This colorimetry system has a colorimetry device, pattern information recorded on a recording object member 1 of feeding paper by a paper feeder 200, paper feeding pitch information of the paper feeder 200. The pattern information includes position information on a pair of position detecting patterns recorded on a first area of the recording object member 1, and performs colorimetry on the pair of respective position detecting patterns by the colorimetry device in a position on the recording object member detectable from the paper feeding pitch information and the position information on the pair of position detecting patterns, and detects a paper feeding error in the recording object member from a colorimetry result by the colorimetry device and information on the pair of position detecting patterns.
