Color adjustment determination method and information processing apparatus

A color adjustment determination method comprising:

• acquiring colorimetric values of at least two portions of a color adjustment image formed on a recording medium by ejecting liquid from a plurality of heads that are arranged at different positions in a line, each head of the plurality of heads including a plurality of nozzles;
• calculating a color difference between the at least two portions of the color adjustment image based on the colorimetric values of the at least two portions of the color adjustment image;
• and
• determining whether adjustment of at least one of the plurality of heads that have ejected the liquid is required based on the calculated color difference.

An information processing apparatus comprising:

• a processor;
• and
• a memory storing program instructions that cause the processor to implement processes of
• acquiring colorimetric values of at least two portions of a color adjustment image formed on a recording medium by ejecting liquid from a plurality of heads that are arranged at different positions in a line, each head of the plurality of heads including a plurality of nozzles;
• calculating a color difference between the at least two portions of the color adjustment image based on the colorimetric values of the at least two portions of the color adjustment image;
• and
• determining whether adjustment of at least one of the plurality of heads that have ejected the liquid is required based on the calculated color difference.
