Abstract
Various embodiments provide methods and apparatuses for removing a printed image and/or image portion(s) of a printed image from at least one side of a media by one or more optical ablations such that the media can be ready for reuse.
Claims20
A method for removing a printed image comprising:
- (a) optically scanning a media having a printed image thereon to map a plurality of image pixel locations of the printed image as a set of electronic image data;
- (b) producing a set of scan line image data from the set of electronic image data;
- and
- (c) conducting one or more optical ablations on the plurality of image pixel locations on the media according to the set of scan line image data to remove the printed image from the media.
1 more element
A print removal apparatus comprising:
- a scanning device configured to map a printed image on a pixel basis as a set of electronic image data, wherein the printed image is on at least one side of a media;
- and
- an image removal station comprising an optical controller and one or more optical sources,
- wherein the optical controller is configured to convert the set of electronic image data into a set of scan line image data and to control an optical ablation on the printed image based on the set of scan line image data, and
- wherein the one or more optical sources are configured to provide the optical ablation.

A method for removing a printed image comprising:
- (a) detecting a plurality of image pixel locations of a printed image on at least one side of a media through a scanning device to provide a set of electronic image data;
- (b) using an area editing controller to select one or more image portions from the printed image to modify the set of electronic image data provided by the scanning device, the modified set of electronic image data corresponding to a plurality of selected image pixel locations of the one or more image portions;
- (c) producing a set of scan line image data by an optical controller from the modified set of electronic image data;
- and
- (d) switching on an optical ablation on the plurality of selected image pixel locations to remove the one or more image portions of the printed image from the media according to the set of scan line image data.
