Patent ID: 7396097

Claim:
A printer ejecting control method for controlling a printer to eject at least three chromatic color inks and additional chromatic color inks having a lower lightness than said at least three chromatic color inks from a print head at the time of printing, which comprises a step of determining an amount of said at least three chromatic color inks and said additional chromatic color inks being ejected from said print head, a step of detecting a limiting condition to limit the above determined amount of the additional chromatic color inks being ejected by detecting a lightness of an area where the additional chromatic color inks are being ejected, said step of detecting said limiting condition detecting said limiting condition when the above determined amount of the additional chromatic color inks ejected is lower than a prescribed first threshold value, and a step of replacing the above determined amount of the additional chromatic color inks being ejected by the amount of said at least three chromatic color inks being ejected when said limiting condition is detected.
