High resolution digital printing with spatial light modulator |
摘要 |
A method of modeling and enhancing the print quality of digital printing, including both electrophographic printing and photofinishing. Pixels are printed with a device such as a DMD, whose pixels provide a steep-sided intensity versus displacement curve of each light spot on the image plane. Holes placed in the pixel can be used to place a dip in the top of the curve, a feature especially useful for electrophotographic printing. The effect of this hole on the image plane can also be flattened, a feature than may be especially useful for photofinishing. The steep-sided intensity curve facilitates the ability to model and predict pixel size.
