Claims
- 1. A method of resolution enhancement of a print image, comprising the steps of:
- establishing a first row of pixels of a spatial light modulator array at an original dots-per-inch resolution;
- determining a desired multiple of the original dots-per-inch resolution; and horizontally offsetting the pixels of successive rows of the array in fractional increments wherein each successive row is offset a horizontal distance substantially equal to an inverse of said multiple from a just previous row.
- 2. The method as claimed in claim 1 wherein said method also includes using pixels of fractional sizes of a standard-size pixel to fill in regions of the print image where standard-sized pixels cause one of the artifacts of overfilling or underfilling a print feature of the print image.
