Document Type and Number:
Japanese Patent JP7392535
Kind Code:
B2
Abstract:
A color prediction model creation device configured to create a color prediction model for predicting color values of a device-independent color system from an ink amount set includes: a first color prediction model creation unit configured to acquire a first spectral reflectance of a color chart printed on a first printing medium by using a first ink amount set, and create a first color prediction model for the first printing medium by learning a correspondence relationship between the first ink amount set and the first spectral reflectance; and a second color prediction model creation unit configured to acquire a second spectral reflectance of a color chart printed on a second printing medium by using a second ink amount set having a smaller number of combinations than that of the first ink amount set, and create a second color prediction model for the second printing medium by learning using the second ink amount set, the second spectral reflectance and the first color prediction model.
