Print response drift compensation mechanism

At least one non-transitory computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:

• receive print response measurement data corresponding to print image printed on a print substrate with a transfer function applied to print image data that defines the print image;
• apply a current compensation transfer function to the print response measurement data to generate first processed print response data;
• determine whether an absolute difference between the first processed print response data and a target response exceeds a first threshold;
• and
• generate an updated compensation transfer function based on the first processed print response data and the target response upon a determination that the absolute difference exceeds a first threshold.

A method comprising:

• receiving print response measurement data corresponding to print image printed on a print substrate with a transfer function applied to print image data that defines the print image;
• applying a current compensation transfer function to the print response measurement data to generate first processed print response data;
• determining whether an absolute difference between the first processed print response data and a target response exceeds a first threshold;
• and
• generating an updated compensation transfer function based on the first processed print response data and the target response upon a determination that the absolute difference exceeds a first threshold.
