Abstract
Systems and methods are provided for measuring a web. One embodiment is a measurement system that includes rollers which receive a web of print media marked with a printed job, a controller which determines that a segment of the web is stationary at the measurement system, an image measurement device that inspects the printed job, and a repositioning mechanism that repositions the segment within the measurement system relative to the image measurement device while portions of the web external to the measurement system remain stationary.
Claims23
A measurement system comprising:
- rollers configured to receive a web of print media marked with a printed job by a continuous form printer external to the measurement system;
- a controller configured to determine that a segment of the web is stationary at the measurement system;
- an image measurement device configured to inspect the printed job;
- and
- a repositioning mechanism configured to reposition the segment within the measurement system relative to the image measurement device while portions of the web external to the measurement system remain stationary,
- wherein the rollers comprise locking rollers configured to brake the web to prevent motion of the web at an entrance and an exit of the measurement system, in response to instructions from the controller, and
- wherein the repositioning mechanism comprises a plurality of rollers configured to translate within the measurement system to reposition the segment relative to the image measurement device while portions of the web external to the measurement system remain stationary.
A method comprising:
- receiving a web of print media marked with a printed job at a measurement system, wherein the web is received from a continuous form printer external to the measurement system;
- determining that a segment of the web that includes the printed job is stationary at the measurement system;
- operating locking rollers to brake the web to prevent motion of the web at an entrance and an exit of the measurement system;
- and
- iteratively:
- repositioning the segment within the measurement system relative to an image measurement device while portions of the web external to the measurement system remain stationary;
- and
- operating the image measurement device to inspect the printed job,
- wherein repositioning comprises operating a plurality of rollers configured to translate within the measurement system to reposition the segment relative to the image measurement device while portions of the web external to the measurement system remain stationary.
A non-transitory computer readable medium embodying programmed instructions which, when executed by a processor, are operable for performing a method comprising:
- receiving a web of print media marked with a printed job at a measurement system, wherein the web is received from a continuous form printer external to the measurement system;
- determining that a segment of the web that includes the printed job is stationary at the measurement system;
- operating locking rollers to brake the web to prevent motion of the web at an entrance and an exit of the measurement system;
- and
- iteratively:
- repositioning the segment within the measurement system relative to an image measurement device while portions of the web external to the measurement system remain stationary;
- and
- operating the image measurement device to inspect the printed job,
- wherein repositioning comprises operating a plurality of rollers configured to translate within the measurement system to reposition the segment relative to the image measurement device while portions of the web external to the measurement system remain stationary.
