A problem that setting (setting the kind of a paper or a printout method) for achieving the print effect (gloss effect or matte effect) at a maximum is very complicated and therefore, a manual setting thereof by a user is very difficult. When image data which a user desires to print and a desire for a print effect to transparent form image data are input, the paper type, conversion of the transparent form image data and a printout method for realizing the print effect are automatically set and printed out.
