Abstract

An image processing method includes: converting a device color CMYK1 that is an input device color depending on an input device into a device color CMYK2 that is an output device color depending on an output device; converting the device color CMYK2 into a spectral reflectance R1 using an output profile showing a relationship between the output device color and a spectral reflectance; converting the spectral reflectance R1 into a spectral reflectance R2, to be reproduced before lamination processing, using a mutual conversion formula of a spectral reflectance before lamination processing and a spectral reflectance after lamination processing; and calculating a device color CMYK3 that is an output device color using the spectral reflectance R2, the output profile, and light source information.
