Abstract
Embodiments described herein are directed to characterizing a media curler for a printing. Test curls can be imposed on media having input curls with known input values using a media curler to be characterized. The media curler can impose the test curls based on curler settings of the media curler. Resulting output values from an interaction between the test curls and the input curls can be measured and the curler settings can be characterized based on the known input values and the resulting output values so that the media curler can be configured to respond to incoming media having a known input curl by applying curler setting to achieve a desired output curl.
Claims19
A media curler characterization system comprising:
- a media curler to be characterized, the media curler being configured to curl a portion of media to form an input curl in a first pass according to a selected input curl setting and in a second pass through the media curler to impose a test curl on the portion of the media having the input curl based on a selected test curl setting to form an output curl, the output curl resulting from an interaction between the input curl and the test curl;
- a measurement module configured to measure a value of the input curl and to measure a value of the output curl;
- and
- a processing device correlating the selected test curl setting with the measured output curl value and the measured input curl value, and calibrating the media curler responsive to the correlation, and wherein the processor controls the operation of the curler to produce a desired output curl based on the correlation of the selected curler setting with the measured output curl value.
A media curler characterization system comprising:
- a first media curler to curl a portion of media to an input curl according to a selected input curl setting;
- a first measurement module positioned downstream of the first media curler, the first measurement module measuring an input value of the input curl;
- a second media curler positioned downstream of the first measurement module, the second media curler being under characterization and imposing a test curl on the portion of the media having the input curl based on a selected test curl setting to form an output curl, the output curl resulting from an interaction of the input curl and the test curl;
- a second measurement module positioned downstream of the second media curler, the second media curler measuring an output value of the output curl;
- and
- a processing device forming a correlation between the test curler setting, the output value and the input value, and the processing device calibrates the media curler based on the correlation to select a curler setting to form an output curl having a desired output value in response to a known input value.
A method of calibrating a media curler for a printing system comprising:
- applying an input curl of known value on a portion of media according to a selected input curl setting;
- applying a test curl to the media portion having the input curl to form an output curl using a media curler to be calibrated, the media curler applying the test curl based on curler setting of the media curler, the output curl resulting from an interaction between the input curl and the test curl;
- measuring the input curl;
- measuring an output value of the output curl;
- correlating the resulting output value with the curler setting and input value with a processor;
- and
- configuring the settings of the media curler responsive to the correlation to calibrate the media curler.
