Color prediction model creation device, color prediction model creation system and color prediction model creation method

摘要

PROBLEM TO BE SOLVED: To create a more accurate color prediction model while reducing the time and labor required for printing and measuring a color chart. SOLUTION: A color prediction model creating device for creating a color prediction model for predicting a color value of a device-independent color system from an ink amount set is a color printed on a first print medium using a first ink amount set. First color prediction to create a first color prediction model for the first print medium by acquiring the first spectral reflectance of the chart and learning the correspondence between the first ink amount set and the first spectral reflectance. The second spectral reflectance of the color chart printed on the second print medium is acquired by using the model creation unit and the second ink amount set in which the number of combinations of ink amounts is smaller than that of the first ink amount set, and the second It includes a second color prediction model creation unit that creates a second color prediction model for a second print medium by learning using an ink amount set, a second spectral reflectance, and a first color prediction model.
