Abstract

A method for adjusting an imaging parameter includes operating a recording head (16) to form a first set of image features (60A) on a media (17). Image features in the first set are formed while the imaging parameter is set to a first predetermined value. The recording head forms a second set of image features (60B) on the media. Features in the second set are formed while the imaging parameter is set to a second predetermined value different from the first predetermined value. Image features of the first set are interleaved with image features of the second set to form an interleaved pattern of image features on the media. Data (47) from the interleaved pattern is generated and analyzed to determine a quantified value representative of banding in the interleaved pattern. The imaging parameters are adjusted based on the quantified value.

Dependent claims

A method for adjusting an imaging parameter, comprising:

operating a recording head to form a first set of image features on a recording media, wherein each image feature in the first set of image features is formed while the imaging parameter is set to a first predetermined value;
operating the recording head to form a second set of image features on the recording media, wherein each image feature in the second set of image features is formed while the imaging parameter is set to a second predetermined value different from the first predetermined value;
interleaving image features of the first set of image features with image features of the second set of image features to form an interleaved pattern of image features on the recording media;
generating data from the interleaved pattern of image features formed on the recording media;
analyzing the data to determine a quantified value representative of banding in the interleaved pattern of image features;
and
adjusting the imaging parameter based at least on the quantified value.
