Abstract
A method of printing an image with an electronically sharpened edge. The method uses an image writing medium to form an image on a substrate. The image is printed using a range of writing medium exposures greater than a standard range. The standard range is the range required to insure that macroscopic areas of the substrate exhibit the full density range of the substrate between Dmin and Dmax. Such printing provides that sharpened edges of the image will be printed with reduced clipping of sharpened edge density. An apparatus for executing the method is also provided.
Claims17
A method of printing an image with an electronically sharpened edge, by using an image writing medium to form an image on a substrate, comprising:
- printing the image using a range of writing medium exposure that is at least 15% greater than a standard range, which standard range is the range required to insure that macroscopic areas exhibit the full density range of the substrate between Dmin and Dmax, so that sharpened edges of the image will be printed with reduced clipping of sharpening edge density.
An apparatus for sharpening and printing a continuous tone image signal by using an image writing medium to form an image on a substrate, comprising:
- means for electronically sharpening edges of the image signal by using an image writing medium to form an image on a substrate, comprising:
- means for electronically sharpening edges of the image signal;
- a printer to print the sharpening image signal using a range of writing medium exposures that is at least 15% greater than the standard range required to insure that macroscopic areas exhibit the full density range of the substrate between Dmin and Dmax, to enable sharpened edges to be printed with reduced clipping of sharpened edge density.
