Patent ID: 8447203

Claim:
A method of operating a printer to apply toner to a receiver, comprising: providing the receiver with an area to be folded and a separate area not to be folded; selecting a fold-area screening pattern having a screen period, and having a screen direction; designating a fold axis in the area to be folded, the fold axis extending in a particular direction, that makes an angle having a magnitude of less than 45° with the screen direction, so that when the receiver is folded, a fold zone will be produced having a width and disposed adjacent to, or containing, the fold axis, and after toner is fused to the receiver, either i) no areas of fused toner will intersect the fold zone; or ii) one or more areas of fused toner will intersect the fold zone and the width of each area measured perpendicular to the screen direction intersecting the fold zone will be less than the screen period; receiving image data to be applied to the receiver in the area to be folded; processing the image data in the area to be folded using the fold-area screening pattern to provide screened data; wherein the processing step further includes reducing the toner coverage of regions of image data in the area to be folded having about 100% coverage; using the printer to apply toner corresponding to the screened data to the receiver; and fusing the applied toner to the receiver.
