Abstract
An apparatus and process overcoats a rendered image on a substrate with a liquid material. The apparatus includes a scanning device and a marking module aligned with the scanning device. The scanning device is used to scan the substrate including the rendered image to acquire scan data. A movable transport member moves the scanned substrate including the rendered image to a location underneath the marking subsystem. A controller uses registration and image data, generated from the scan data, to overcoat the rendered image on the substrate.
Claims19
An apparatus for overcoating a substrate, the substrate having image rendered regions representing areas of the substrate having an image rendered thereon and non-image regions representing areas of the substrate having no image rendered thereon, with a liquid material, comprising:
- a movable transport member for moving the substrate;
- a scanning device for scanning the substrate and an area around the substrate to acquire scan data;
- a controller, operatively connected to said scanning device, for generating, from said scan data, image data, said image data including rendered image data corresponding to image rendered regions representing areas of the substrate having the image rendered thereon and non-rendered image data corresponding to non-image regions representing areas of the substrate having no image rendered thereon;
- said controller generating, from said scan data, registration data, said registration data corresponding to a location of a boundary between the substrate and the area around the substrate;
- and
- a marking module, operatively connected to said controller and located downstream of said scanning device, to create tactilely discernible image rendered regions;
- said marking module overcoating the image rendered regions on the substrate with the liquid material in response to registration data and the image data received from the controller to create tactilely discernible image rendered regions;
- said marking module not overcoating the non-image regions on the substrate with the liquid material in response to registration data and the image data received from the controller to create tactilely discernible image rendered regions.
A method for overcoating a substrate, the substrate having image rendered regions representing areas of the substrate having an image rendered thereon and non-image regions representing areas of the substrate having no image rendered thereon, with a liquid material, comprising:
- (a) supplying the substrate to a scanning device, wherein the scanning device is disposed upstream of a marking module;
- (b) scanning the substrate and an area around the substrate, with the scanning device, to acquire scan data;
- (c) generating registration data from the scan data, the registration data corresponding to a location of a boundary between the substrate and the area around the substrate;
- (d) generating, from the scan data, image data, the image data including rendered image data corresponding to image rendered regions representing areas of the substrate having the image rendered thereon and non-rendered image data corresponding to non-image regions representing areas of the substrate having no image rendered thereon;
- (e) communicating the registration data and the image data to the marking module;
- (f) moving the substrate from the scanning device to position the substrate under the marking module;
- (g) responsive to received registration data and image data, overcoating the image rendered regions on the substrate with liquid material from the marking module to create tactilely discernible image rendered regions;
- and
- (h) responsive to received registration data and image data, not overcoating the non-image regions on the substrate with the liquid material from the marking module to create tactilely discernible image rendered regions.
An apparatus for overcoating the substrate the substrate having image rendered regions representing areas of the substrate having an image rendered thereon and non-image regions representing areas of the substrate having no image rendered thereon, with a clear UV curable gellant ink, the clear UV curable gellant ink being dispensable in the form of ink drops, the rendered image being rendered by a xerographic marking process, and the image rendered regions including silicone oil, comprising:
- a movable transport member for moving the substrate;
- a scanning device for scanning the substrate and an area around the substrate to acquire scan data;
- a controller, operatively connected to said scanning device, for generating, from said scan data, image data, said image data including rendered image data corresponding to image rendered regions representing areas of the substrate having the image rendered thereon and non-rendered image data corresponding to non-image regions representing areas of the substrate having no image rendered thereon;
- said controller generating, from said scan data, registration data, said registration data corresponding to a location of a boundary between the substrate and the area around the substrate;
- and
- a marking module, operatively connected to said controller and located downstream of said scanning device, to create tactilely discernible image rendered regions;
- said marking module overcoating the image rendered regions on the substrate with the clear UV curable gellant ink in response to registration data and the image data received from the controller to create tactilely discernible image rendered regions;
- said marking module not overcoating the non-image regions on the substrate with the clear UV curable gellant ink in response to registration data and the image data received from the controller to create tactilely discernible image rendered regions.
The apparatus of claim 19, wherein said controller determines a background color of the substrate and determines said image data representing the image rendered regions on the substrate from the scan data based upon a comparison of the determined background color of the substrate and the scan data.
