Patent ID: 6975426

Claim:
A method for preparing an upstream profile and a downstream profile, the method comprising the steps of: preparing a downstream profile; preparing an upstream profile using the prepared downstream profile, both of the upstream profile and the downstream profile corresponding to characteristics of an image recording device and being used to process image data that is used for recording images on a recording medium by the image recording device, the upstream profile being used for performing a prior process on the image data and the downstream profile being used for performing a subsequent process on the image data already processed by the prior process; and judging, after the downstream profile preparation process and before the upstream profile preparation process, whether the downstream profile has been properly prepared by processing image data using the prepared downstream profile, by controlling the image recording device to record the processed image data on a recording medium, by examining a recorded result, and by judging whether the downstream profile has been properly prepare based on the examined result, and when it is judged that the downstream profile has been improperly prepared, preventing the upstream profile preparation process from being performed based on the improperly-prepared downstream profile.
