Abstract
An assembly and method for image data acquisition is provided for obtaining image data representative of a printed work on a moving web in a printing press. The assembly includes a light source for illuminating the web, an optical fiber taper for minifying an image from a first end to a second end of the taper, wherein the first end of the taper is in optical communication with the printed work on the web, a sensor coupled to the second end of the taper, and a processor for receiving image data representative of the printed work from the sensor.
Claims13
An image data acquistion assembly for obtaining image data representative of a printed work on a moving web in a printing press, comprising:
- a light source for illuminating the web,
- an optical fiber taper for minifying an image from a first end to a second end of the taper, wherein the first end of the taper is in optical communication with the printed work on the web,
- a sensor coupled to the second end of the taper and having a plurality of pixels, and
- a processor for receiving image data representative of the printed work from the sensor.
An image data acquisition assembly for obtaining image data representative of a printed work on a web moving in a first direction, comprising:
- a line scan sensor arranged in a second direction that is transverse to the first direction and having a plurality of pixels each having a pixel width along the second direction,
- an optical fiber element having a first side in optical communication with the printed work on the web and a second side coupled to the line scan sensor, the optical element coupling an image at a respective area of the printed work to one of the plurality of pixels, wherein the width of each respective area is greater than the pixel width, and
- a processor for receiving image data from the line scan sensor.
A method for acquiring image data representative of a portion of a printed work on a moving web, comprising the steps of:
- using an optical fiber taper comprising a bundle of fibers to minify an image of a printed work on the web from one end of the taper to a second end of the taper,
- connecting the second end of the optical fiber taper to a plurality of pixels of a line scan sensor, and
- shifting the image data out of the line scan sensor to a processor.
