Printed color prediction method and device, profile generation method and device, color conversion method and device, and color conversion system

摘要

A printed color prediction method includes: a step of acquiring the spectral reflectance in a protective film non-coating region of a printed matter that the protective film does not coat; a step of estimating the optical physical property value of the protective film; a step of acquiring the spectral distribution of an observation light source; a step of estimating the color change property due to the interaction between the printed matter as a base matter and the protective film; and a step of predicting the colorimetric value of a protective film-attached printed matter, based on the acquired spectral reflectance of the printed matter, the optical physical property value of the protective film, the spectral distribution of the observation light source and the color change property due to the interaction.
