Abstract:
A color patch that was printed based on a plurality of test ink quantity sets prepared in advance is image inputted; a graininess index is calculated based on the inputted color patch image; the graininess index on a printing medium obtained when printing is performed according to an arbitrary ink quantity set is predicted based on a graininess profile produced based on the corresponding relationship between the test ink quantity set and the graininess index.
